Detailed Description

Affine transformation for 3D containing a transformation matrix and a translation vector.

No perspective transformation is possible, only translation, rotation, scaling and shear.

Constructor & Destructor Documentation

AffineMatrix3D()

None AffineMatrix3D	(		self,
		cvb.Matrix3D	matrix,
		cvb.Point3D	translation
	)

Member Function Documentation

identity()

cvb.AffineMatrix3D identity

(

)

An identity transformation.

Returns

cvb.AffineMatrix3D An identity transformation.

inverse()

None inverse

(

self

)
