This is an excellent example of how complex images with the look of "radiosity" can be rendered quickly and efficiently with the NuGraf Rendering System.

The scene was created by Mr. Jim Mattison (Verity Grafix) in AutoCAD r12 using AME solids then exported to the NuGraf Rendering System via DXF for rendering. The scene consists of 307,700 polygons. To simulate the soft shadows and diffuse interreflections typical of a radiosity rendering Mr. Mattison added 18 light sources to the scene (16 point lights and 2 spot lights) of which 12 of the point lights and the 2 spot lights casted shadows. NuGraf's "shadow map" shadow casting algorithm was used to create the nice soft shadows quickly and in a conservative amount of memory (all shadow maps were computed at a resolution of 512x512 pixels).

A scene of this complexity and large number of lights would normally bring most rendering programs to their knees. However, NuGraf was able to efficiently render it on a simple P75 Pentium computer with only 32Mb of memory (running Windows NT). This is achieved through NuGraf's efficient memory allocator which allocates and deallocates memory on a per-object, per-polygon and per-vertex basis.
