Rendering Pipeline

「渲染管道」

• General (rasterization) Rendering Pipeline (RP)「一般（光栅化）的渲染管道（RP）」
• Ray Tracing (RT) 「光线追踪（RT）」
• Rasterization「光栅化」 vs. Ray Tracing (RT)

Rasterization vs. RT

• Rasterization RP is well optimized (i.e., it is very FAST)
  • Model rasterization RP supports more realistic lighting
    • 光照贴图
    • 光探头「Light Probes」
    • Real-time global illumination「照明」
• RT simulates real physics of light (i.e., it is very costly)「RT模拟了真实的光的物理特性（也就是说，它的成本很高）。」
  • NVIDIA 深度学习超级采样 (DLSS)
  • RT denoising「去噪」 is again very costly
