tps_warp — 3D deform op

Data kinds: deformation × pointspoints

Call: import fullseye as fs; fs.ledger.tps_warp(model, points) (to call the implementation directly, import deform3d; deform3d.tps_warp(model, points); from the registry, ops3d.get("tps_warp"))

Usage

Deform a point set with a TPS model.

> The detailed description below is the original text — the summary and the headings are translated.

f(x) = [1,x,y,z]·a + Σ_i w_i·U(‖x − p_i‖) を評価する。

引数:

model: `tps_fit` が返した dict。

points: (M,3)(または長さ3の1次元)。変形したい点群。

返り値:

(M,3) 変形後の点群(入力が1次元なら (3,) を返す)。

例外:

ValueError: model の形式不正、または points の形状不正。
