GRAF: Generative Radiance Fields for 3D-Aware Image Synthesis

Schwarz, Katja, Liao, Yiyi, Niemeyer, Michael et al.

Understand

While 2D generative adversarial networks have enabled high-resolution image synthesis, they largely lack an understanding of the 3D world and the image formation process.

  • Thus, they do not provide precise control over camera viewpoint or object pose.
  • To address this problem, several recent approaches leverage intermediate voxel-based representations in combination with differentiable rendering.
  • However, existing methods either produce low image resolution or fall short in disentangling camera and scene properties, e.g., the object identity may vary with the viewpoint.
