A few projects I worked on back in college (2013-2014)
Spatial acceleration structures on the GPU
A library of GPU-accelerated spatial data structures, including a uniform grid for accelerating nearest neighbor searches and a k-d tree for accelerating ray tracing.
CUDA-parallelized Monte Carlo path tracer
Full global illumination, realistic diffuse surfaces, color bleeding, caustics, area lights, soft shadows. Also supports Fresnel refractions for glass materials and texture mapping for spheres and cubes.
Projective dynamics for fast simulation
First public implementation of the 2014 SIGGRAPH paper Projective Dynamics: Fusing Constraint Projections for Fast Simulation by Kavan, et al.
A CUDA-based rasterized graphics pipeline with vertex shading, primitive assembly, perspective transformation, rasterization, and fragment shading. An exercise to learn how a rasterization pipeline can generate graphics without raycasting or OpenGL.
Automatic face detection and replacement
Automatic face detection and replacement algorithm using MATLAB’s CascadeObjectDetector feature detector class, projective warp homographies, and Poisson blending.
