TransformDecomposeAffine Method (Vector3d, Transform)

Decomposes an affine transformation. A transformation is affine if it is valid and its last row is [0, 0, 0, 1]. An affine transformation can be broken into a linear transformation and a translation. Note, a perspective transformation is not affine.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 6.12
public bool DecomposeAffine(
	out Vector3d translation,
	out Transform linear


Type: Rhino.GeometryVector3d
Translation vector.
Type: Rhino.GeometryTransform
Linear transformation.

Return Value

Type: Boolean
True if successful decomposition.
If X.DecomposeAffine(T, L) is true then X == Translation(T)*L. DecomposeAffine(T,L) succeeds for all affine transformations and is a simple copying of values.
