tps_fit — 3D deform op

• Data kinds: points × points → deformation

• Call: import deform3d; deform3d.tps_fit(src_ctrl, dst_ctrl, lam=0.0) (or ops3d.get("tps_fit"))

Usage

Fit a 3-D thin-plate spline from control-point correspondences.

• 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)

• nonrigid_deform — py -3.11 examples_3d/nonrigid_deform.py

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