Fully functional early version of my radiosity engine.

640x480x32 screenshot of my 'Cornell box' showing radiosity pass from area light. 3 passes were used to render this image.
All other light types use a ray-tracing first pass before radiosity distribution.
The patches cover an area of 8x8 pixels each and no post-processing has been applied. Interpolation will eventually be applied to smooth the colours and raise the patch resolution to 4x4 pixels
The boxes are 8 units above the floor - hence the shadow area under the box edges.
This is not a static rendered image. This is a 'world' that can be moved about in.
This radiosity engine will form the basis of lighting worlds in future 3D game releases, such as 3D PacMan and Dragontorc.


Here are a couple more screenshots from an updated version of my renderer. The screenshots show the results of the ray-tracing first pass. No radiosity has been performed, so there is no reflected light.
The light is a bright blue-white area light. The first screenshot is texture-mapped. The second shows the light maps only.
