Legacy Demos of the Taichi Graphics Library (2016)
Material Point Method, Affine Particle in Cell, FLIP...
Rigid Body Simulations
Physically based Rendering
Path-traced Images (early project)
Stochastic Progressive Photon Mapping with QMC
Equal time comparison between AMCMCPPM (left) and naive SPPM (right). The light source is far away and MCMC smartly guides photons to visible areas.
Unified Path Sampling/Vertex Connection and Merging
Volumetric Kelemen-style Metropolis Light Transport
Opaque v.s. Subsurface Scattering
Multiple Importance Sampling (MIS) test scene (originally by Eric Veach). Equal-sample comparisons between importance sampling of light sources + BSDF (top), only BSDF (bottom left), only light sources (bottom right).
Microfacet with GGX NDF
