About

Simple C++/DX12 framework for my bachelor thesis "Dynamic real-time global illumination algorithms on modern GPU hardware and software" (paper).

Features

  • Deferred Rendering
  • Shadow Mapping
  • GI w/ Reflective Shadow Mapping (indirect diffuse)
  • GI w/ Light Propagation Volume (indirect diffuse)
  • GI w/ Voxel Cone Tracing (indirect diffuse + specular + AO)
  • SSAO
  • Asynchronous compute
  • DXR: Reflections + Blur, Ambient Occlusion + Blur

Optimizations

Reflective Shadow Mapping:

  • main pass in compute (+async)
  • efficient upsample & blur of main pass' output in compute (+async)

picture

Light Propagation Volumes:

  • flux downsample in compute
  • DX12 bundle for propagation passes

picture

Voxel Cone Tracing:

  • main pass in compute (+async)
  • anisotropic mipmapping passes in compute (+async)
  • efficient upsample & blur of main pass' output in compute (+async)

picture

SSAO:

  • TODO: downscaled version
  • TODO: move to compute with LDS optimizations
  • TODO: move to async

RTAO:

  • TODO: replace blur with proper filtering

Comparison

No GI -> RSM -> LPV -> VCT -> offline path-tracer
