extract_surface_points — 3D tsdf_fusion op

Data kinds: sdfpoints

Call: import tsdf_fusion; tsdf_fusion.extract_surface_points(tsdf: 'np.ndarray', weight: 'np.ndarray', bounds: 'Bounds', res: 'int') -> 'np.ndarray' (or ops3d.get("extract_surface_points"))

Usage

Extract surface points (M,3) from the TSDF zero crossing (no marching cubes needed; linear interpolation).
