transform1

A transform.

transfrom2

A transform.

Description

The postmultiply-transforms function postmultiplies the partial 3 x 3 matrix represented by transform1 by the partial 3 x 3 matrix represented by transform2 , storing the result in transform1 . In the result, the translation, scaling and rotation operations contained in transform2 are effectively performed after those in transform1 .

transform1 = transform1 . transform2
