Detailed Description

Affine transformation matrix for 3D.

This is a compact version of ␈ CVC3DMatrixH with the last row being { 0, 0, 0, 1 }. So no perspective transformation is possible, but translation, rotationand scaling is.)

Defines a transformation.

Parameters

matrix : Optional[cvb.Matrix2D] The matrix part.

translation : Optional[cvb.Point3D] The translation part.

Member Function Documentation

identity()

cvb.AffineMatrix3D identity

(

)

An identity transformation.

Returns

cvb.AffineMatrix3D An identity transformation.

invert()

None invert

(

self

)

Inverts this transformation if possible.

Might cause division by zero.
