Hello author.Although hash-grid performs well in novel view synthesis, it does not maintain continuity across voxels. The hash grid is spatially discontinuous. How to calculate the gradient of SDF in space and calculate Eikonal Loss? Using analytical gradients from PyTorch may cause surface holes.How did you solve the problem?
