Struct AffineMat3#
The generic AffineMat3f class provides support for affine 3x3 matrices.
An affine 3x3 matrix is a 3x3 matrix whose right hand column is always 0,0,1.
Affine 3x3 matrices are often used for 2d transformations such as scaling, rotation and translation.
Unless otherwise noted, methods and operators always return a new vec3 containing the result, without modifying any parameters or 'self'.
This allows you to chain operators together easily just like 'real' expressions.
