Matrix33

value class Matrix33

Matrix holds a 3x3 matrix for transforming coordinates. This allows mapping Point and vectors with translation, scaling, skewing, rotation, and perspective.

Matrix includes a hidden variable that classifies the type of matrix to improve performance. Matrix is not thread safe unless getType() is called first.

Parameters

mat

9-element array of floats representing the matrix in row-major order

`
| scaleX   skewX  transX |
|  skewY  scaleY  transY |
| persp0  persp1  persp2 |
