Baking Neural Radiance Fields for Real-time View Synthesis

goal: run nerf on a macbook

• train a nerf -> store grid values at a sparse grid
  • opacity, diffuse color, feature vector for view dependent affects
  • feature vector is integrated, and then transformed by an mlp -> rendered per ray
    • this mlp can be trained after storing -> fine tuning
• Cauthy loss for density: sparse prior
  • on coarse samples only
