initial values for OccupancyGrid #93

Closed ghost closed 2 years ago

ghost commented 2 years ago

I have a quick question out of curiosity regarding the initial values for OccupancyGrid.

Do the initial values from some prior geometries for OccupancyGrid accelerate the process? did you try it? Thanks in advance!

You may actually want to the initialize the radiance field network instead of the occupancy grid, as the occupancy grid is designed to synchronize with the radiance field network.

OK. Thanks!

Hi,

I want to force render some parts present in the occupancy grid, I'm looking for something like here.

But I'm working on v3.5 (1x occ_grid) any ideas how to proceed ?

need something during eval, similar to occ_eval_fn to update the states of the grid points in training

Thanks!
