Not so tiny path tracer
- Linux gcc-7 /clang-7 / gcc-10 / clang-10
- Windows MSVC 2019
Note: This program is being modified to meet the requirements of the CSE168 course by Prof Ravi Ramamoorthi.

Cornel Box (1200 x 1200 x 1024spp,about 35mins)
Matte, dielectric, glass and Cook-Torrance material
-
Debugger
-
QuadLight(640 x 480, 128spp, cosine weight sampling)
-
QuadLight(640 x 480, 128spp, Blinn-Phong importance sampling) This one looks much better.
-
Ajax(768 x 768, normal integrator) Not difficult but amazing.
