Transform

k3d.transform.transform(bounds: List[float] | None = None, translation: List[float] | None = None, rotation: List[float] | None = None, scaling: List[float] | None = None, custom_matrix: ndarray | None = None, parent: Transform | None = None) → Transform

Return a Transform object.

Parameters:

• bounds (array_like, optional) – Dimensions bounds taking precedence over separate bound arguments, by default None. [xmin, xmax, ymin, ymax, zmin, zmax] or [xmin, xmax, ymin, ymax].

• translation (array_like, optional) – [tx, ty, tz] translation vector, by default None.

• rotation (array_like, optional) – [gamme, rx, ry, rz] rotation vector (radians), by default None.

• scaling (array_like, optional) – [sx, sy, sz] scaling coefficients, by default None.

• custom_matrix (_type_, optional) – Matrix of numbers, by default None. Must have four columns.

• parent (Transform, optional) – Optional parent transform, by default None.

Returns:

Transform object.

Return type:

Transform
