Just a baby render last night on my netbook with the latest additions to the raytracer, which would include global illumination.  Still an issue to sort out with fog.  It should be based on the distance from the last ray and not always from the camera.  The result is the far away objects are getting blown out.

If your asking if it's a path tracer, the answer is no, on a few technicalities.  A path tracer makes no distinction between an object in a scene and a light source.  We do have a light source with traditional lambert lighting.  For one reason, we're not doing a high dynamic range image based lighting scheme.

We're more like global illumination by radiosity.

When in the world did I start talking this way?
