Visibility of buttons on the Tool bar can be adjusted on the Toolbar tab of the Options box.

 

 

'Project' button group

 

Save project

 

Save working project to a file.

 

 

"Camera" button group

 

New

 

Create new camera with default parameters.

 

In the dialog box appeared you can change camera number, name, type of the camera which determines the kind of icon by which it will be displayed. If necessary, you can enter additional information on the created camera (for example: purpose, a place and features of installation).

 

Later it is possible to change name, number, type of the camera and the additional information in the Camera list box.

Cameras can be numerated sequentially with the help of the Numerate cameras tool.

Cameras are displayed by different icons only if the Display camera type box in the Options box is marked.

 

On the Line type panel it is possible to choose line type by which the icon of the camera and View area projection bounds will be drawn. When displaying spatial resolution is disabled, projection will be filled (hatched) by the color of assigned line type. Later it is possible to change line type using Change line type tool.

Hatch style is determined by style of a line type, assigned to the camera (solid, dash, dot, dash dot etc.).

 

After entering all necessary data click OK, to cancel the operation click Cancel.

 

If there is already a camera with chosen number in the current project, VideoCAD will ask to specify, whether you would like to rewrite it.

After camera creation specify by clicking a place for the new camera on the layout.

Just after camera creation the moving mode will be switched on. When placing will be completed, click Select/Edit button or press ESC.

 

It is convenient to create new cameras with already set parameters by copying and pasting existing ones.

 

At the moment of placing new camera or pasting copied camera, its base height is set to the base height of the active layer.

 

Save to project

 

All the specified and calculated parameters of the Active camera and layout are saved to the current project.

 

Saving is performed automatically at many operations.

 

Camera list

 

Clicking this button opens Camera list box, in which camera list of current project is displayed. Active camera is highlighted by red frame. Any camera can be activated, removed, renamed, found on layouts, it is possible to show 3D image from any camera. It is also possible to sort cameras in the list. For carrying out any manipulations with the camera first select its name in the list by single clicking.

 

See more: Camera list

 

Table of cameras

 

Show interactive Table of parameters of all cameras in the project. The table can be exported to *.txt, *.csv, *.htm, *.rtf, *.xls formats.

 

See more: Table of cameras

 

Active camera combo box

 

Using the combo box, you can fast activate any camera in the project. To activate a camera, just choose its name in the list.

To find the active camera on the layout, right click on the combo box then choose Find camera item.

 

 

"View" button group

 

View area edges

 

Show the Active camera view area edges, calculated according to parameters in the Camera Geometry box.

 

Line type can be changed in the options box.

 

 

When View area projection bounds is disabled, but Shadows is enabled, the View area edges is shown simplified in the form of two rays if the angle of camera rotation around its axis is multiple of 90 degrees (Camera 2) or in the form of one ray if the angle of camera rotation around its axis is not multiple of 90 degrees  (Camera 3).

 

If the line type of camera coincides with default line type for camera icons, specified in the Options box, then for this camera the line type of View area edges is taken from the Options box>Lines>System line types>Bounds. This line type is assigned to new cameras by default (Camera 32 on the figure).

 

Default line type for cameras is Line 21.

 

If another line type was assigned to the camera, the View area edges of this camera is drawn by this line type assigned to the camera, as well as the View area projection bounds and camera icon.  (Camera 33...38).

 

Thus you can draw different cameras and their view areas by different colors, thickness and line style.

 

 

 

 

A button state at the moment of camera saving determines whether the view area edges of the given camera will be displayed when this camera is inactive.

 

If selected cameras exist on the current layout, except the active camera, this button changes view and operates the visibility of View area edges of all selected cameras simultaneously.

 

View area projection bounds

 

Show the bounds of the Active camera view area projections or sections of the view area on two levels calculated according to parameters in the Camera Geometry box.

 

 

Submenu of the button:

 

 

1. Projection - show View area projection bounds of the active camera.

 

Projection is calculated according to a simple rule:

 

A point on the horizontal projection is considered visible if a vertical segment, formed by this point in the range of heights from the view area lower bound height to the view area upper bound height, is visible wholly.

 

 

2. 2 levels - simultaneously show 2 sections of the view area by 2 horizontal planes, located on the height of the lower and upper bounds of the view area.

 

The upper section is shown by thick lines.

If in the submenu of the Fill projections button Filling is chosen, the section of the lower plane is displayed as filling, and the section of the upper plane as hatching (Camera 35).

 

If in the submenu of the Fill projections button Hatching is chosen, the section of the lower plane is displayed as hatching, and section of the upper plane as filling (Camera 36).

 

 

When visualizing spatial resolution with two levels, the lower section is not at the view area lower bound but at the height of measuring spatial resolution, determined in the spatial resolution pattern assigned to the camera. Spatial resolution is rendered on this level.

 

If the height of measuring spatial resolution is set to AUTO, then:

if the view area projection bounds is set to 2 Levels, the height of measuring spatial resolution is set at the view area lower bound;

 

if the view area projection bounds is set to Projection, the height of measuring spatial resolution is set at the halfway between the lower and upper bounds of the view area ( as in  VideoCAD7 and earlier versions ) .

 

Difference between the View area projection bounds and Shadows buttons is that the View area projection bounds are built without obstacles on the scene but the Shadows are built  considering obstacles. Both buttons can be used simultaneously in various combinations.

 

3. Off. - don't show.

 

When View area projection bounds is disabled, but Shadows is enabled, the View area edges is shown simplified in the form of two rays if the angle of camera rotation around its axis is multiple of 90 degrees or in the form of one ray if the angle of camera rotation around its axis is not multiple of 90 degrees.

 

If the line type of camera coincides with default line type for camera icons, specified in the Options box, then for this camera the line type of View area projection bounds is taken from the Options box>Lines>System line types>Bounds. This line type is assigned to new cameras by default.

 

If another line type was assigned to the camera, the View area projection bounds of this camera is drawn by this line type assigned to the camera, as well as the View area edges and camera icon.

A button state at the moment of camera saving determines whether the bounds of the given camera view area projections will be displayed when this camera is inactive.

 

If selected cameras exist on the current layout, except the active camera, this button changes view and operates the visibility of View area projection bounds of all selected cameras simultaneously.

 

Fill projections

 

Hatch or fill by blend color view area projections of active camera ( if these projections exist) calculated according to parameters in the Camera Geometry box.

 

If the line type of camera coincides with default line type for camera icons, specified in the Options box, then hatching (filling) projections of this camera is performed by grey color by default (Camera 30 on the figure).

 

If another line type was assigned to the camera, then hatching (filling) projections of this camera is performed by a color of this line type assigned to the camera. (Camera 41,42).

 

If the Spatial resolution is enabled, then colors of hatching (filling) projections is  determined by Spatial resolution parameters (Camera 43).

 

Drop-down menu:

 

1. Hatching - hatch projections.

 

2. Filling - fill projections by blend semitransparent color.

If the Hatching item is chosen, but in the drop-down menu of the Spatial resolution button the Gradient item is chosen, then the projections will be hatched by a bold style of hatch without gradient.

 

Transparence of filling in the Graphics window can be adjusted in the Options box.  Transparence of filling in the  3D World window can be adjusted in the 3D World.

 

If in the submenu of the View area projection bounds button, 2 levels is chosen then:

If in the submenu Filling is chosen, the section of the lower plane is displayed as filling, and the section of the upper plane as hatching (Camera 35).

 

If in the submenu Hatching is chosen, the section of the lower plane is displayed as hatching, and section of the upper plane as filling (Camera 36).

 

3. Off - don't hatch and fill view area projections.

 

If Off is chosen in the Fill projections and Shadows, then filling view area faces in the 3D World is not shown.

 

If the line type of camera coincides with default line type for camera icons, specified in the Options box, then for this camera Filling is performed by Gray color and Hatching by DiagCross style. (Camera 32)

 

Default line type for cameras is Line 21.

 

If another line type was assigned to the camera, then for this camera filling is performed by a color determined by color of the line type and hatch style is determined by style of the line type (Camera 33...38).

 

Thus you can fill and hatch projections of different cameras by different colors and hatch styles.

 

 

A button state at the moment of camera saving determines whether the filling or hatching of the view area projections of the camera will be displayed when this camera is inactive.

 

If selected cameras exist on the layout, except the active camera, this button changes view and operates the visibility of filling (hatching) projections of all selected cameras simultaneously.

 

Spatial resolution

 

Fill in different colors regions on the view area projections of the active camera, depending on the spatial resolution within these regions.

Colors of the regions and the boundary values of the spatial resolution are determined by the spatial resolution pattern assigned to the camera.

In the Spatial resolution box you can edit the patterns and assign them to cameras.

 

 

Drop-down menu:

1. Discrete colors -  fill the regions in discrete colors in accordance with a spatial resolution at the far bounds of the regions.

 

2. Gradient - fill the view area projection in gradient color according to the spatial resolution at each point on the projection.

 

In case of gradient color is chosen, the colors at the far region bounds equal to the colors of the spatial resolution pattern, but between the bounds color changes smoothly, as well as real spatial resolution.

Gradient reflects the spatial resolution more accurately and looks impressive, but discrete colors are more intuitive and easy to use..

 

If the Gradient item is chosen, but in the drop-down menu of the Fill projections button the Hatching item is chosen, then the projections will be hatched by a bold style of hatch without gradient.

 

Calculation of gradient demands a lot of resources and increases redraw time.

 

3. Off. - don't display spatial resolution

 

If in the submenu of Shadows button or View area projection bounds button (when Shadows is Off) the 2 levels is chosen, then lower section is not at the view area lower bound but at the height of measuring spatial resolution, determined in the spatial resolution pattern assigned to the camera. Spatial resolution is rendered on this level.

 

If the height of measuring spatial resolution is set to AUTO, then:

if the view area projection bounds is set to 2 Levels, the height of measuring spatial resolution is set at the view area lower bound;

 

if the view area projection bounds is set to Projection, the height of measuring spatial resolution is set at the halfway between the lower and upper bounds of the view area ( as in previous versions ) .

 

In the active camera editing mode, the regions of spatial resolution can be displayed in the vertical projection, with the height of spatial resolution measurement (horizontal red line).

 

 

In the Dome mode the Spatial resolution is calculated without taking into account pan and tilt angles of camera. It is assumed that the camera can pan and tilt freely, and spatial resolution is calculated at the center of the field of view.

 

The  Spatial resolution button controls displaying spatial resolution on 3D view area and the Coverage in the 3D World window .

 

A button state at the moment of camera saving determines whether the spatial resolution of the camera will be displayed when this camera is inactive.

 

If selected cameras exist on the layout, except the Active camera, this button changes view () and operates the visibility of spatial resolution of all selected cameras simultaneously.

 

See also: Spatial resolution box, Visualization of the camera control area projections and spatial resolution within them.

 

Shadow

 

Display horizontal projection of the view area of the active camera taking into account shading from constructions and 3D models.

Click to expand
Click to expand

 

Shadows - a powerful yet easy-to-use tool of VideoCAD. Shadows are calculated for all positions of cameras, shading objects can be located at any point of space. You should only enable calculation of shadows with the help of this button.

 

Shading takes into account the camera installation height and all 3 coordinate of constructions and 3D models (including heights).

 

Drop-down menu:

 

1. Within projection - display view area projection taking into account shadows.

Shading is calculated according to a rule:

 

A point on the horizontal projection is considered visible if a vertical segment, formed by this point in the range of heights from the view area lower bound height to the view area upper bound height, is visible wholly.

 

By the same rule the horizontal projections of view area are calculated. Changing the height of the lower and upper bounds of view area could change conditions of calculation of shading.

 

2. 2 levels -simultaneously show 2 sections of the view area by 2 horizontal planes, located on the height of   lower and upper bounds of the view area. From the sections subtract shadows from obstacles

 

Click to expand
Click to expand

 

If in the submenu of the Fill projections button Filling is chosen, the section of the lower plane is displayed as filling, and the section of the upper plane as hatching (Camera 35).

 

If in the submenu of the Fill projections button Hatching is chosen, the section of the lower plane is displayed as hatching, and section of the upper plane as filling (Camera 36).

 

If in the submenu of the Spatial resolution button Discrete colors or Gradient is chosen, then lower section is not at the view area lower bound but at the height of measuring spatial resolution, determined in the spatial resolution pattern assigned to the camera. Spatial resolution is rendered on this level.

 

If the height of measuring spatial resolution is set to AUTO, then:

if the view area projection bounds is set to 2 Levels, the height of measuring spatial resolution is set at the view area lower bound;

 

if the view area projection bounds is set to Projection, the height of measuring spatial resolution is set at the halfway between the lower and upper bounds of the view area ( as in VideoCAD7 and previous versions).

 

3. Dome - display projection of the territory controlled by the camera in 360 degrees, without view area borders, but only taking into account the shadowing.

 

When the Dome item is chosen, actually the control area of a dome (PTZ) camera is displayed.

 

The Dome mode is also useful for choosing the best installation place for fixed cameras to make required areas reachable for the cameras.

 

In the Dome mode all shaded areas from the specified camera position become visible.

 

In the Dome mode the Spatial resolution is calculated without taking into account pan and tilt angles of camera. It is assumed that the camera can pan and tilt freely, and spatial resolution is calculated at the center of the field of view

.

In the Graphics window calculation of shadows in the Dome mode is performed like in the Within projection mode, ie according to the rule:

A point on the horizontal projection is considered visible if a vertical segment, formed by this point in the range of heights from the view area lower bound height to the view area upper bound height, is visible wholly.

 

In the 3D World in the Dome mode the territory controlled by the active camera is displayed as coverage on the environment. The coverage in the 3D World is displayed for the active camera only.

 

4. Off - disable shadow calculation and displaying.

 

Difference between the Shadows and View area projection bounds buttons is that the View area projection bounds are built without obstacles on the scene but the Shadows are built  considering obstacles. Both buttons can be used simultaneously in various combinations.

The Shadow button works in conjunction with the Spatial resolution and the Fill projections buttons. Depending on the state of these buttons, shadows can be displayed in different ways: as filling, as shading, as a border lines, with mapping spatial resolution or not.

 

The calculation of shading - resource-intensive operation. During the shadow calculation on the Shadow button red frame flashes .

Automatic shadow calculation is performed only for the active camera. To recalculate shading for a particular camera - activate this camera. To recalculate shading for all selected cameras, click Main Menu>View>Recalculate shadows.

To temporarily disable the automatic calculation of shading (keeping already calculated shadows visible) clear the item Main menu>View>Calculate shadows for active camera.

 

The calculation of shading from 3D models is disabled by default to save resources. To enable the calculation of shading from the 3D models, check the Options box> Miscellaneous> Shadow>Calculate shadows for 3D models.

Additionally, for each 3D model, which must be taken into account when calculating the shading:

double click on the model to switch it to editing state;
on the appeared Current construction parameter panel check Shadow checkbox.

 

To force to calculate shadows from a type of 3D model you can mark Shadows checkbox on the 3D Models window while editing the type of the 3D model.

 

Whether or not a specific construction takes into account in the calculation of shading determines by the Shadow checkbox of the line type used for the construction.

.

You can ignore constructions of specified layers while calculating shadows, using the Shadows row in the table of layers.

 

A button state at the moment of camera saving determines whether the shadows of the camera will be displayed when this camera is inactive.

 

If selected cameras exist on the layout, except the Active camera, this button changes view ( and operates the visibility of shadows of all selected cameras simultaneously.

 

When calculating 3D view areas and coverage of the active camera in the 3D World window, shadows are calculated independently from shadows in the Graphics window. Calculation of shadows in the 3D World is rougher, but much faster.

 

Accounting 3D models as obstacles in the 3D World window does not depend on the state of the Calculate shadows from 3D models checkbox in the Options box.

 

 

 

 

 

 

 

 

If Off is chosen in the Fill projections and Shadows, then filling view area faces in the 3D World is not shown.

Model of active camera

 

Using this combo box, you can choose a model for the Active camera.

The list consists of two parts:

 

Under =Used models =  header  there are camera models listed which are already used in the project . All parameters of these models can be seen on Used models tab in the Table of camera models.

 

Under =All models = header there are all camera models listed which are available in the database of models. Parameters of these models can be seen and edited on All models tab in the Table of camera models.

 

To assign a model, just choose its name in the list.

 

As a result of model assignment to the active camera, model parameter values will be assigned to parameters of the active camera. After that changing some parameters will be locked.

 

There is =Unassigned = string in the bottom of the list. Choose this string if it is necessary to remove model assignment from the active camera. As a result of removing model assignment all parameters of the active camera will be unlocked and can be changed.

 

You can change model of all selected cameras simultaneously. For this purpose:

Select necessary cameras on the layout
Right click on this combo box, then click on the Assign to selected cameras pop up item.

Lens focal length combo box

 

The box duplicates a corresponding box in the Camera Geometry box to enhance the convenience when using the graphics window.

 

When moving the cursor to the box with a lens focal length the information on the lens view angles appears.

 

If a model is assigned to the camera, and the model has fixed focal length lens, then you can not change the focal length.

 

If a model is assigned to the camera, and the model has a lens with limited variable focal length, then you can change focal length within the limits only. When approach to the limit values, the box will become crimson.

 

You can change focal length in wide range of 0.5-1000mm of cameras, which have not assigned model or the assigned model have not specified limits of the lens focal length.

 

If the active camera is panoramic then the lens focal length box is colored by aqua-green.

 

Changing the lens focal length, and therefore the calculated values ​​of view angles of a camera with enabled modeling lens distortion will lead to detuning parameters of distortion and warping view area form. To correct the mismatch you should set new values ​​of the actual view angles, taking into account the changed values ​​of calculated view angles.

 

You can change lens focal length of all selected cameras simultaneously. For this purpose:

Select necessary cameras on the layout
Right click on this combo box, then click on the Assign to selected cameras pop up item.

 

See more: Lens focal length

Sensitivity parameters take part in modeling only if 3D Video is opened and illumination modeling is switched on.

 

See more: Sensitivity and Resolution

 

Spatial resolution

 

Show or hide the Spatial resolution box. In this box it is possible to create and edit patterns of spatial resolution and field of view size visualization. In the box there are prepared spatial resolution patterns according to the following criteria: Home Office Scientific Development Branch, Home Office Guidelines for identification, P 78.36.008-99, Australian Standard AS4806: Closed Circuit Television, European Standard EN 50132-7, ISO/IEC 19794 Biometric data interchange formats. Also in the box there are examples of images are automatically displayed for each region of spatial resolution.

 

See more. Spatial resolution box, Spatial resolution button.

 

Depth of field

 

Show or hide the Depth of field calculation box.

 

When the depth of field box is visible, next to all cameras in the horizontal projection the following lines are displayed:

These lines are calculated according to the depth of field parameters of each camera at the height of depth of field measurement.

 

If the focus plane or the plane at the hyperfocal distance not intersect the horizontal plane at the height of depth of field measurement within the view area projection, then the focus plane or the plane at the hyperfocal distance are not displayed.

 

If the near or the far bound of the sharpness area not intersect the horizontal plane at the height of depth of field measurement within the view area projection, then this bound is not displayed.

 

The absence of near and far bounds of the sharpness area indicates that the sharpness area completely covers projection of view area, thus the depth of field does not reduce the resolution of the camera.

This tool doesn't take into account camera rotation around its main optical axis, shadows and lens distortion.

 

See more: Depth of field calculation box, Control of Depth of Field in the horizontal projection.

 

3D Video

 

Show or hide the 3D Video window. The 3D Video displays the image from the Active camera. During the image generation in the 3D Video window on the 3D Video button red frame flashes .

"Edit" button group

 

Buttons of this group are used for the editing constructions, 3D objects, cables, texts and cameras. In this case the status bar in the bottom of the Graphics window displays hints.

When editing an object the projections should be taken into account. Different projections are different views, though connected ones. Moving objects correctly between projections has no sense and is impossible to perform.

To start the editing select the desired objects.

Choosing the items from the pop-up menu that appears when clicking the graphics area by the right mouse button performs the commands of this group as well.

 

 

Stop operation

 

Stop the current operation. Use also Esc.

 

Erase

 

Erase the selected objects. To select objects use the button Select/Edit.

If there are no selected objects this button is disabled.

Use also Del.

 

You can not erase the Active camera.

 

Select/Edit

 

With this button chosen the first corner of selection window appears when clicking any empty place of graphics area once. Clicking it again completes the designation of selection window.

All the objects, which hit in the selection window and reside on the projection coinciding with one being clicked for the first time, will be selected. However, the earlier selected objects not hitting in the selection window will revert to normal state.

 

If Ctrl is pressed at clicking, the objects within the selection window are inverted, on the contrary, state of those not hitting in the selection window remains the same.

 

It is possible to select objects by one by clicking their image once, thus enabling the earlier selected objects to revert to normal state.

If Ctrl is pressed at clicking, the objects are inverted, and the state of the rest remains the same.

You can make a 3D model insensitive to mouse click by Lock checkbox in the 3D Models window.

 

During construction 3D scenes it is often necessary to place some constructions one over another at a different height, made by means of different line types.

To select one or more construction, located one over another, made by means of different line types:

make the line type panel visible, for example by double clicking any construction;
choose on the panel the line type of construction you want to select;

select the construction by clicking.

 

Just repeat clicking at the same place without moving the cursor. Thus objects under the cursor will be selected sequentially.

 

Layers are very useful for multi-level constructions.

 

An object can be inaccessible for selection if it belongs to a not enabled layer

 

To move objects on the foreground or background use menu items: Bring to front, Send to back.

       Editing state of objects

 

To translate an object into editing state double-click its image. After that pink grips appear on the object base points.

When moving the cursor over this point its image changes.

 

To edit an object click beside a base point with a grip and move the cursor. After clicking for the second time, the changed object is set up.

If on one side of a construction a circle is displayed, the construction can be rotated around its axis by gripping the circle by mouse.

 

To switch the circle into the editing state you need to double-click on its center or on the point on its radius that appears during the process of construction.

To switch  the arc into the editing state you need to double-click on its center or on either of its two ends.

 

When editing a rectangle or a mask, then several points will move at a time, the rectangle or the mask remaining square.

If Ctrl is pressed when editing a rectangle or a mask, then one point will move only.

 

When editing a Double line or Wall, the whole Double line or Wall will be moved.

"Constructions" button group

 

Buttons of this group are used to perform measurements and constructions. The status bar in the bottom of the Graphics window and the Current construction parameter panel display the results of measurements. The constructions can be used for 3D modeling the video surveillance object, for specifying the required view areas, objects, obstacles, etc.

Each construction is attached to the projection containing its initial point. The constructions can be moved, deleted, rotated, edited, copied, mirrored , scaled, changed draw order, hidden using the buttons of Edit group.

 

Constructions made in the horizontal projection are also displayed in the 3D Video  and 3D World . At this, the line corresponds to a vertical rectangle, the point - to a vertical segment, the rectangle - to a parallelepiped, circle - to a cylinder, etc.

Constructions are stretched throughout the height and become 3D objects.

 

Minimal and maximal height of each object is determined by parameters of line type, by which the construction is made.  The heights can be set separately for each object, during constructing and editing by means of current construction parameters panel. Heights of constructions are calculated relative to base height of a layer to which the construction belongs.

Color of constructions is determined only by line type, which is used at constructing.

 

Constructions can be distributed by Layers. By changing parameters of a layer you can change some parameters of all constructions belong to the layer. At the moment of drawing, construction is placed on the active layer.

 

To enhance speed and convenience of drawing, VideoCAD uses global and local snaps.

 

The construction coordinates are displayed relatively to the chosen origin of coordinates. The coordinates of constructions belonging to one camera only (focal plane, optical axis, field-of-view size, test object,change view area upper bound) are always displayed relatively to the Active camera.

 

When choosing a button of this group a line type panelor a font type panel appear, allowing to change the line or font types.

Filling is similar to a mask, but can be of any color, and also in the form of different hatch type. Color of filling is defined by the color of line type, by which the filling is made, and type of hatching or its absence - by style of this line type.

 

Fillings, as well as other objects, could be edited by moving separate vertexes, and thus could be stretched on various objects.

 

In the 3D Video and 3D World fillings are not shown.

 

See also: "Constructions" button group

 

3D model

 

The button opens submenu, in which there are 3D models which are present in the program library.

 

When any item in the submenu is chosen, clicking in the graphics area specifies the place for a 3D model.

 

3D models placement is possible in the horizontal and vertical projections, however only 3D models placed in the horizontal projection will be visible in the 3D Video and 3D World.

 

 

In the horizontal projection the 3D models are displayed in the top view, in the vertical projection - in the side view, and in the 3D Video and 3D World models are as 3D objects.

 

Horizontal and vertical projections for displaying in the Graphics window can be created in the 3D Models window.  

 

3D models can be moved, rotated, copied, changed draw order as other VideoCAD objects.

 

The default height of the 3D models above the ground is determined by the maximal height of the line type which was chosen when the 3D model was being placed. The height can be set separately for each 3D model using the current construction parameters panel.

 

To change 3D model height above the ground, select the 3D model, then change line type or switch the 3D model to editing state by double clicking on it and change value in the 3D H box on the Current construction parameters panel.

 

By default the 3D models are on the ground and constructed by the line type with the number, specified on the Lines tab of the Options box. This line type has the maximum height equal to 0.

Heights can also take on negative values, in this case 3D model plunges under ground.

For example, to place a 3D model on a surface: construct the surface by the rectangle tool using line type with the required maximum height, place the 3D model on it, and then change 3D model line type to the line type of the surface.

 

In multilevel 3D projects heights are calculated relative to the base height of a layer the which the 3D model belongs. By changing the base height a layer you can move up or down all 3D models and constructions on the layer

 

In the Editing state using the Current construction parameters panel you can resize 3D models separately on axes.

To do this, enter new values into X, Y, Z boxes during 3D model editing. If the box is marked, change of any size leads to proportional change of other sizes, thus model proportions are not broken. 3D model height above the ground is displayed and can be changed in 3D H box.

 

In the editing state, 3D models are displayed with square grips and pink circle.

You can rotate the 3D model by the mouse using the circle, scale 3D model on X and Y axis using the square grips. You can move the 3D model by pressing the left mouse button on the 3D model, as well as in the selected state.

 

 

 

       Moving 3D models

 

3D models can have velocity vectors. Model with specified nonzero speed will move with this speed along a specified direction when modeling exposure time, Rolling Shutter, interlace distortions and creation of animated images.

To set speed to 3D model you should enter a nonzero value in the Speed box in the Current construction parameter panel during the placement or editing 3D models.

 

If a 3D  model has non zero speed, then the velocity vector is displayed.

 

If 3D model is selected then length of the velocity vector equals to the distance in meters (feet) which the 3D model pass per second (crimson arrow).

If 3D model is in the normal state, the length of the velocity vector equals to the distance which the 3D model passes for the period between successive frames of the Active camera (black arrow).

 

* the length of the velocity vector of a 3D model in the normal state is inversely proportional to the frame rate of the active camera. Thus we can see how many times the moving 3D model gets into the frame of the active camera.

You can edit the velocity vector of 3D model in editing state by moving its terminus.

 

\

You can hide the velocity vectors of all 3D models using the Velocity vectors menu item.

 

 

       License plate of cars

Let's consider 3D models - cars with license plates. License plate type, the same for all car models, is determined by the file number.bmp  file in the directory \Models\, and the plate size - by the corresponding settings in the Options box on the 3D modeling tab. This opportunity allows using the same models in different countries with different license plates.

 

To make cars appear in the 3D Video with the license plate of your country:    

create a *.bmp  file with the image of you license plate;

!! The size of file sides, in pixels, must be equal to powers of two: 16,32,64,128,256,512,1024,2048 ....

replace the file number.bmp by your file;
specify the sizes of your license plate in the Options box.

 

 

       3D models of terrain

 

You can use 3D model of terrain of video surveillance, for example: buildings, territory etc. Cameras, constructions, other 3D models can be placed inside the 3D model-territory. VideoCAD offers special tools for working with 3D models-territories

 

See more: 3D Models window, 3D World window, Work with 3D model-territory.

 

 

       Adding new 3D models, manage 3D models

 

You can add new 3D models to the library using Add 3D Model menu item.

 

You can add, delete, duplicate 3D models, distribute 3D models by directories in menu, get projections of 3D models for the Graphics window  using the 3D Models window.

 

Files of 3D models in *.vcm format can be exported from SketchUP and 3ds max using plugins. Custom 3D models for VideoCAD can be created in SketchUP and 3ds max.

3D image

 

This tool is similar to Inclined rectangle. As well as the inclined rectangle it allows to place a rectangle in three-dimensional space at any angle.

 

But this rectangle can be "covered" by any raster image in *.bmp , *.jpg, *.gif, *.tiff, *.png formats. The image can be a photo or a figure.

In  *.bmp and *.jpg files, pixels of the image can be transparent if they have a color coincided with the color of the left bottom pixel. Thus the image border can take any form.

 

In *.png  files transparent pixels will be displayed transparent.

 

In many cases raster images can replace 3D models which are difficult to make. They can be used for modeling many objects from banknotes and plates up to a complex background.

 

After choosing this button the Loading 3D image dialog box appears. After choosing a file in *.bmp,*.jpg,*.jpeg,*.png,*.gif,*.tif  or *.tiff format place 3D image in the same way as Inclined rectangle.

On the Current construction parameter panel the minimal height corresponds to the bottom bound of this rectangle and the maximal height - to the top bound.

 

In the Graphics window the top of 3D images is displayed by thick line.
