DDGI

  • 主页，NVIDIA
  • 效果上：DDGI + sota glossy ray tracing + deferred shading 可以和 pt 媲美

Introduction

  • Probe-based global illumination
    • trade off：accuracy、flexibility、performance
    • 之前的是针对静态场景、静态光源的预烘焙【计算代价大】，漏光问题
  • Real-time GI
    • light 的表示
      • lightmap representations
      • irradiance and radiance probes
      • voxelized representations of the scene or lighting information
  • 【TODO】
