In the K-Planes paper, Fridovich-Keil et al. describe 3 losses:

  • Space TV: encourages sparse gradients on spatial axes.
  • Temporal smoothness: penalizes accelerations (laplacian filter on time axes)
  • Sparse transients: encourages separation of space-only and spacetime content.

This PR adds these 3 losses, using code from https://github.com/sarafridov/K-Planes

There is one loss for the main network, and one for all proposal networks combined (cf. loss coeficients)

Additionally, it adds support for temporal rendering in the viewer.
