deformation_to_points — REPRCONV `algebra` op

• Data kinds: deformation → points

• Call: import reprconv; reprconv.deformation_to_points(deformation) (or opsreprconv.get("deformation_to_points"))

Usage

A TPS `deformation → its control points (N,3). The exit from deformation`.

`tps_fit が返す dict の ctrl` を取り出す。「この歪みはどこに

固定されているか」を点群語彙で見るためのもので、一方向

(制御点だけからは重み `w とアフィン項 a` は復元できない)。

Args:

deformation: `ctrl を持つ dict(tps_fit` の返り)。

Returns:

(N, 3) float64。

Raises:

ValueError: dict でない / `ctrl` が無い / 形状不正 / 非有限。
