Opaque Raytracer

This is the webpage of my (Vlad Stamate) raytracer, called "Opaque". 

Please see the "Features" page for more information of what Opaque can do. 
Also check the "News" page for development updates. 
Pass by "Thanks" page since I came here by sitting on shoulders of giants (and friends).

Quick description:

Opaque is a raytracer that implements few global illumination algorithms such as direct raytracing, path-tracing, photon-mapping and bi-directional raytracing. It also does distributed rendering with my own client/server/slave implementation. It supports Windows, OSX and Linux. It can use the CPU or GPU for rendering.

Why

Why a ray tracer? Why not! Opaque is meant as a testbed for different physically correct (loose term here) rendering algorithms. I have already implemented classical raytracing, photon mapping, path-tracing and bi-directional path-tracing.
