VideoCAD Lite full changelog

The following parameters have been separated:
Image sensor size and size of active area of the image sensor;
Aspect ratio of image sensor and aspect ratio of output image of the camera.

image sensor size and size of active area of the image sensor;
aspect ratio of image sensor and aspect ratio of output image of the camera.

· New project file format *.vc7. There are possibilities of export and import of the previous project format *.vmp, supported by versions from 4 to 6.
· Unlimited quantity of cameras in one project. In the previous versions each project could contain no more than 100 cameras.
· Unlimited quantity of constructions on each layout. In the previous versions each layout could contain no more than 5000 constructions.
· Quantity of line types is increased to 2000.

· Resource-intensive operations are allocated in separate threads. This allows working in the graphics window without delays and also get considerable gain in efficiency on modern multicore processors.
· 3D image generation is allocated in a separate thread. This allows working in the graphics window with opened 3D window without delays for redrawing 3D images. The priority of the 3D window thread can be switched. During image generation in the 3D window on the 3D window button blinking red frame appears.

· Camera parameters modeling (spectral response; number of pixels; resolution; minimum scene illumination at known signal-to-noise ratio, IRE and aperture; maximum signal-to-noise ratio; electronic shutter; AGC; Back Light Compensation; gamma correction).
· Lens parameters modeling (focal length; aperture; Auto Iris DC and Video Drive). Calculating and modeling Depth of field based on calculated aperture.
· Modeling cameras, switching into black and white mode in case of low illuminance: day/night with removable IR filter and easy day/night with permanent IR filter.
· Enhanced modeling of DVR parameters (vertical and horizontal digitization, brightness, contrast, compression, vertical and horizontal sharpness).
· Modeling specific distortions which are arisen as a result of mismatching output image size and number of pixels on camera's video sensor.
· Modeling images based on scene, lens, camera and DVR models. Calculating and modeling signal-to-noise ratio and contrast.
