Module gpu_voxel 

GPU voxel grid operations (CPU mock implementation).

Provides a binary occupancy grid and a Signed Distance Field (SDF) built from it, plus morphological dilation/erosion and a marching-cubes triangle count estimate. All routines are CPU references for the GPU backend.

Structs

GpuVoxelGrid

A 3-D voxel grid storing binary occupancy and an SDF.

Functions

gpu_march_cubes_count

Count the estimated number of triangles that would be produced by marching cubes on the current occupancy field.

gpu_sdf_from_voxels

Compute an approximate SDF from the binary occupancy grid using BFS.

gpu_voxel_dilate

Morphological dilation: mark a voxel as occupied if any 6-connected neighbour is occupied.

gpu_voxel_erode

Morphological erosion: clear a voxel if any 6-connected neighbour is empty.

gpu_voxelize_mesh

Rasterize a triangle soup into the voxel grid.
