Theory, analysis and applications of 2D global illumination
2012
ACM Transactions on Graphics
We investigate global illumination in 2D and show how this simplified problem domain leads to practical insights for 3D rendering. We first derive a full theory of 2D light transport by introducing 2D analogues to radiometric quantities such as flux and radiance, and deriving a 2D rendering equation. We use our theory to show how to implement algorithms such as Monte Carlo ray tracing, path tracing, irradiance caching, and photon mapping in 2D, and demonstrate that these algorithms can be
