TransformDecomposeAffine Method (Transform, Vector3d)

Decomposes an affine transformation. 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)
Syntax
public bool DecomposeAffine(
	out Transform linear,
	out Vector3d translation
)

Parameters

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

Return Value

Type: Boolean
True if successful decomposition.
Remarks
If X.DecomposeAffine(L, T) is true then X == L* Translation(T). DecomposeAffine(L, T) may fail for affine transformations if L is not invertible, and is more computationally expensive then X.DecomposeAffine(T, L).
