Small path tracer experiment based on smallpt and pbrt
Most of the formulas used are probably physically wrong, but the algorithm produces interesting images nevertheless.
Potentially interesting features include:
- Support for HDR environment maps
- Diffuse, purely specular & glass BRDFs
- Depth of field (kind of)
- Area & point lights (w/ explicit light sampling)
- Triangle meshes (slow, without acceleration structures)
- Progressive rendering
- Supersampling
Requires SFML2
