3D panel



Default license plate - The default license plate is used by default with 3D models with license plates, as well as in the 3D Test, 3D Test at the view area bounds and on test images of the Pixel density box.

To change the default license plate just click on its image.


In addition to the default license plate, you can assign different license plates for different 3D models with numbers using the Assign license plate button on the Current construction parameters panel. In addition, in the 3D Models window, you can add  license plates to any 3D models (even if they do not have plates), set the places and angles of rotation of license plates.


Plate height

- vertical size of the license plate in the 3D Video and 3D World.


Plate width

- horizontal size of the license plate in the 3D Video and 3D World.


Specify in these boxes the sizes of license plate by default.


You can assign license plates other than the default license plate. As license plates any raster images can be used. See Materials and license plates.


Ground color

- ground color in the 3D Video. In the 3D World the ground color is specified separately.  


Licence plate and test chart antialiasing

If these boxes are checked- the license plates and test chart are displayed more realistic in the 3D Video, but at that it takes more time for repainting the 3D Video and there can be errors on some outdated graphic card.


Space limits


At the  use of some outdated graphic card the occurrence of distortions on the image in the 3D Video is possible. For reduction of the distortions it is recommended to reduce Model space.


The increase of the near space limit has the much greater influence on distortions, than reduction of the far space limit.

The objects which are closer to the camera, than near space limit or farther than far space limit will not be displayed, but the distortions of the objects which are between space limits will be reduced or removed completely.


To simulate long-range cameras with a large focal length, it is required to expand the Space limits and the Maximum distance of drawing view area. The maximum simulation distance may be limited by the graphics card, at long distance artefacts may occur especially on 3D models.


Background res.


In this box you can set resolution of vector background in the 3D Video and 3D World.


Redrawing 3D Video


On this panel you can optimize the speed of redrawing 3D Video according to computer's performance, current design features and designer's habits.


Draw 3D Video in separate thread


Use separate program thread for redrawing image in the 3D Video. When the checkbox is checked, redrawing the 3D Video doesn't  retard work of other windows but is carrying out with delay.


This checkbox is checked by default.  If errors occur while redrawing the 3D Video, try to clear this checkbox.


With the help of the Priority combo box, you can control the priority of redrawing 3D Video in separate thread. The higher the priority is, the faster the image  in the 3D Video is redrawn, but the more hinders operation in the Graphics window.


In the the Mode combo box you can switch the method of redrawing image in the 3D Video.

Normal - drawing image in the usual way, in one stage;
2 stage - drawing in 2 stages. on the first stage "raw" image is rapidly shown, and then a resource-intensive image processing is carried out;
2 stage+2 priority - like a 2 stage, but the first stage is faster with higher priority.


Redraw 3D image only by clicking


Modeling complex 3D scenes, especially taking into account illumination, require high computer performance.

If the image in the 3D Video is redrawn too slowly and that hinder operation in the Graphics window, mark this box. After that the image in the 3D Video will be redrawn automatically only at activation of cameras. To force redrawing click on the image.


The box is duplicated in the Main menu of the 3D Video.


Disable image processing


If this box is marked then the image processing will not be modeled.

Modeling gamma, noise, brightness, contrast, resolution, sharpness, compression will be disabled.


Redraw speed will increase, errors with outdated video cards may be removed.


The box is duplicated in the Main menu of the 3D Video.



Modeling Depth of Field and Shutter


Using Speed <> Accuracy slider you can choose a compromise solution between realism and performance of modeling depth of field, exposure time and rolling shutter.

Rotakin speed (rpm)


In the box you can specify number of revolutions of the Rotakin object in revolutions per minute.


Loading 3D models


In the combobox, you can select the order of loading 3D models at program start.


Headers -  load headers of all 3D models, and the 3D models used in the project load as a whole;

Wholly - download all 3D models from the library as a whole at the start of the program.


Speed unit for 3D models


In the box, you can select the unit for measuring the speed of 3D models: meters per second or kilometers per hour.


PIP mode by default


In the box, you can select the PIP mode that will be applied by default for new cameras. Select OFF to disable PIP for new cameras.


View area border accuracy


The accuracy of vectorization of view area boundaries in the 3D World window.
