GITechDemo changes:
*Some RSM optimizations in the form of a quarter-resolution indirect light accumulation buffer, which gets additively color blended over the full-res light accumulation buffer using edge-aware bilateral upscaling *Added a new PCF filter type with a 4x4 Poisson Disk kernel rotated 0, 90, 180 and 270 degrees around its center (although more bandwidth intensive, it further improved the shadow's jagged edges) *Created a script for automating the build process LibRenderer changes: *Small bug fixes
