Right now we support trilinear interpolation of SPC but we don’t officially support the creation of the dual octree (trinkets), which you need to perform interpolation. Current implementation I have (https://github.com/nv-tlabs/nglod/blob/6cb8d10cc4b44f709f855dc98fa8e6e58ba7c1fd/sdf-net/app/spc/spc_utils.py#L107) is Pandas and CPU based, and runs fast but is not ideal.
Not sure what the right algorithm is, need time (or equivalently find time) to think about it.
