Matrix33

class Matrix33(mat: Float)

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.

Functions

fun asMatrix44(): Matrix44

When converting from Matrix33 to Matrix44, the third row and column remain as identity:

open operator override fun equals(other: Any?): Boolean

open override fun hashCode(): Int

fun makeConcat(other: Matrix33): Matrix33

Creates Matrix33 by multiplying this by other. This can be thought of mapping by other before applying Matrix.

fun makePreScale(sx: Float, sy: Float): Matrix33

open override fun toString(): String
