Data kinds: positionpoints

Call: import reprconv; reprconv.position_to_points(position) (or opsreprconv.get("position_to_points"))

Usage

A position `(z, y, x) → a one-point set (1, 3). The exit from position` (invertible).

`positionvolregion.vol_rle_centroid` などが返す 3-tuple で、

順序は (z, y, x)(`vol_rle_centroid` の docstring が明示している)。

点群も voxel 由来なら同じ順なので、そのまま 1 行の点群にできる。

Args:

position: 長さ 3 の列 (z, y, x)。

Returns:

(1, 3) float64。

Raises:

ValueError: 長さが 3 でない / 非有限。
