We are playing around with our CUDA ray tracing software. The design philosophy is to create a real-time ray tracing experience that allows the user to play with the visual parameters and get an instant feedback. This is not something revolutionary but ray tracing is such a flexible rendering technique, so the basic software can be used in a lot areas. In this demo the user can change and update the material properties at runtime.
We finally found a decent model

Refraction and diffuse materials, rendering time 45 sec.
But we still like some good old programmers art. The above image is a rendering that uses ambient occlusion together with classic ray tracing.
No ray tracing post without Sponza!
