BLAS: Support for bitgrid & DDA marcher #148

Open orperel opened 1 year ago

orperel commented 1 year ago

In addition to the current SPC raymarcher, the following NGP features would be useful to integrate:

  1. Bottom level acceleration structure: occupancy bitgrid
  2. DDA ray marcher, backed by a CUDA kernel using the above blas (train time)
  3. Wavefront raymarcher kernel (inference time)
