Transform.DecomposeRigid

Public Class

Decomposes a rigid transformation. The transformation must be affine.

Namespace: Rhino.Geometry

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**6.12

Syntax

public TransformRigidType DecomposeRigid(
  out Vector3d translation,
  out Transform rotation,
  double tolerance
)

Parameters

translation

Type: Rhino.Geometry.Vector3d.
Translation vector.

rotation

Type: Rhino.Geometry.Transform.
Proper rotation transformation, where R*Transpose(R)=I and det(R)=1.

tolerance

Type:System.Double
The evaluation tolerance.

Return Value

Type: TransformRigidType
The rigid type.

Remarks

If X.DecomposeRigid(T, R) is 1, then X ~ Translation(T)*R. If X.DecomposeRigid(T, R) is -1, then X ~ Transform(-1) * Translation(T)*R. DecomposeRigid will find the closest rotation to the linear part of this transformation.
