Yellow glass teapot, specular transmissive sphere and reflective wall

Glass material is implemented using weighted-material combined with specular transmission and specular reflection.

Specular transmission teapot

Teapot is perfectly tramsmissive, the caustic effect can be well captured using photon mapping.

Transmissive teapot and reflective back wall

Prism with 80% reflection and 20% transmission material

Both caustic and reflective effects can be captured in this test scene.

Final gathering for indirect lighting

Test for kd-tree and photon shooting tasks
