Greetings people

I'm looking for a free or relatively cheap radiosity renderer that I can use for the lighting in my openGL models. I'm using MAVERIK, a sort of VR toolkit implemented in C.Basically it's something like Mesa but with built-in navigation and functions that make manipulation of objects(geometry & surface parametres)easier.

As you can understand I'm not looking for a stand alone application with a GUI and stuff but something which can be incorporated with OpenGL ie in real time navigation of the models.

If anyone can help please let me know

Thanks

Something like that ?

Thanks for the link, this looks promising, I'm testing it right now

If anyone knows other software similar to this one please drop a line :)

Unfortunately I can't run the thing-get an exception on the viewer program. I'll try to work round it but if I remember correctly it only performs calculations on triangle meshes and not primitives such as spheres etc. I think I'll need something that works with such higher lever primitives.

In most implementations of true radiosity, renderers only support triangles/quadrilaterals. What I mean by this is that high-level primitves like spheres would be tesselated. Raytacing based methods that use irradience caching for in-direct lighting is probably better suited for the primitves you need. Try searching for API's with photon mapping implementation. For simple models you might get interactive speeds.
