points_to_voxel — 3D transform op

• Data kinds: points → voxel

• Call: import match3d; match3d.points_to_voxel(points, size, bounds=None, device='cpu', smooth=0.0) (or ops3d.get("points_to_voxel"))

• GPU: this op has a GPU path (device="cuda")

Usage

Point set (N,3) → a density voxel volume (size³). Splatted with scatter_add, optionally Gaussian-smoothed.

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.
