CAD Rendering: Virtual Photography with ART VPS

Step Three – Apply Lighting

There are two approaches to lighting: standard and high-dynamic-range imaging (HDRI). Standard lighting techniques use computer graphics lights to replicate real-life light sources. RenderPipe complements the full range of light types found in most 3D packages.

ART VPS also provides the option of adding an HDRI image to be used for lighting, reflections, shading and other effects. HDRI has revolutionized the external lighting process. In conjunction with ART VPS rendering hardware, it has made Virtual Photography a reality.

HDRI images contain high resolution contrast data, recorded photographically on location, which is used by ART VPS’s ray-tracing renderer to light the scene. The image also appears as the background environment. This means you are able to drop a computer model into a scene and it will be fully integrated into an apparent real-world environment.

Step Four – Apply Cameras and Render

RP cameras work just like the standard 3ds max, Maya, VIZ or CATIA cameras. In 3ds max, Maya and VIZ they have additional controls for motion blur, depth of field, and lens effects.

The ART VPS RenderPipe renderer is integrated with the application. A user selects RenderPipe as the active renderer giving access to a selection of RenderPipe options, including chalk preview, image quality, ray depth, and a preview that shows the entire rendering in progress, rather than just the partial fill shown by many software renderers.

Step Five – The End Results

This scene was rendered in 12 minutes and 34 seconds at a resolution of 1828×1332 pixels.

Because of the way the system works, should it be necessary to make changes to the rendering, it only takes about 15 minutes to modify and re-render the image to incorporate, for example, silver paint work and chrome alloys.

This image illustrates the potential of the Virtual Photography system, allowing the CAD derived object to take on the light, shade and reflection properties of its surroundings.
