Materials
- Seems I had misunderstood diffuse relfection: http://en.wikipedia.org/wiki/Diffuse_reflection The BRDF function is correct, dot(normal, lightDir) But the importance sampling whould prioritize the normal of the surface, and drop to 0 at the tangent, just like the BRDF.
- Fresnel term
- Texturing
  - Procedural
  - Bitmapped
- Refraction
  - Dispersion
- "Directionality" of emitted light
Recursive geometry - fractals
Better camera model
- Depth Of Field
- Lens flare / bloom
- Tone mapping
