Similar Images I'd like to reproduce:

Motivation:

See how to simulate the appearance of marble or Jade using subsurface scattering. Possible methods are Hanrahan and Krueger's Siggraph '93 paper that applying subsurface scattering to plants and faces. But in the end the model it uses a BRDF to represent model, which cannot account for the light transport effect between different points. Here, I am trying to use photon maps to represent the incident flux, then use the diffuse approximation to evaluate the BSSRDF by sampling all photons. The method is proposed in Henrik W. Jensen, Juan Buhler, Proc. of SIGGRAPH 2002.

Plan:

Since I have not time to build a model by myself, I will use Stanford Bunny or Happy Buddha. The scene is rendered using subsurface scattering, also, add environment mapping to make it more realistic. If time permits, I'd like to add some more fancy effects, like caustics on the model ( put it into the water).
