Global illumination is about, gathering photon distribution. photon distribution is largely a result of geometry and participating media, resulting in different amount of photons in volume and surface.
Is it possible to transform global illumination to a different space, which is easy to compute photon distribution, then transform the result to the 3D domain?
Is there a math model to capture the characteristics of global illumination, which is efficient to compute? 🙂
Or, what’s the characteristics of global illumination? It’s the result of light transport in participating media and surfaces.
TODO:
- Understand light transport, from a different perspective than space-time – rather, from the perspective of universe!
- Simplify light transport to capture essential characteristics of light transport
- Understand geometry
- Simplify geometry representation: is it possible to represent it in a different domain?
- Understand participating media
- Simplify participating media: is it possible to represent it in a different domain?
Ideas:
- Grind down geometry representation to see how it looks in a different space
Light transport is observed in scientific efforts of capturing the statistics of light transport. For example, light transports in straight line is a conclusion of statistics of photon transportation. Is it possible to abstract the light transport mechanism?
