Methods

createMatrix

createMatrix(scaleX, scaleY, posX, posY): MatrixObject
Generate a 2D transformation matrix with the given scale factor and translation.
Parameters
- scaleX: number
  
  The horizontal scale factor.
- scaleY: number
  
  The vertical scale factor.
- posX: number
  
  The horizontal translation.
- posY: number
  
  The vertical translation.
Returns MatrixObject
A 2D transformation matrix.

createMatrixIdentity

createMatrixIdentity(): MatrixObject
Generate the identity matrix which will map to itself.

Returns MatrixObject
A 2D identity matrix.

matrixIsFinite

matrixIsFinite(matrix): boolean
Checks if all members of the matrix are finite aka a valid number.
Parameters
- matrix: MatrixObject
  
  The matrix to check.
Returns boolean
True if all members of the matrix are finite.

matrixMultiply

matrixMultiply(matrix1, matrix2): MatrixObject
Perform a matrix multiplication.
Parameters
- matrix1: MatrixObject
  
  The first matrix to multiply.
- matrix2: MatrixObject
  
  The second matrix to multiply.
Returns MatrixObject
The result of the matrix multiplication.
