query_distance — 3D occupancy op

• Data kinds: sdf × points → signal

• Call: import occupancy; occupancy.query_distance(esdf_grid, bounds, res, query_points, mode='trilinear') (or ops3d.get("query_distance"))

Usage

The ESDF values (M,) at arbitrary world coordinates (M,3) (`mode` = 'trilinear' interpolation or 'nearest').

References (sample data, literature)

• 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.

Runnable examples (verified samples that actually call this op)

• occupancy_esdf — py -3.11 examples_3d/occupancy_esdf.py

Ops the type connects to (they accept signal as input)
