Motivation

I plan to see how the appearance of marble or Jade can be simulated using subsurface scattering. One possible method that apply subsurface scattering to plants and faces is described in [2]. But finally it still uses a BRDF function to represent the model, which cannot account for the light transport effect between different points accurately. So I will use the fast subsurface scattering method in [1]. First, use photon maps to represent the incident flux, then use the diffuse approximation to evaluate the BSSRDF by sampling all photons. Hierarchical structure is applied to accelerate the rendering procedure.

Plan

Since I have no time to build a model by myself, my model will be Stanford Bunny or Happy Buddha. Subsurface scattering is used to render the model and environment mapping is added to make the scene more realistic. If time permits, I would like to try some more fancy effects, like caustic photon maps on the model.
