getMatrix3
Gets the upper left 3x3 matrix of the provided matrix.
// returns a Matrix3 instance from a Matrix4 instance
// m = [10.0, 14.0, 18.0, 22.0]
// [11.0, 15.0, 19.0, 23.0]
// [12.0, 16.0, 20.0, 24.0]
// [13.0, 17.0, 21.0, 25.0]
const b = new Matrix3();
Matrix4.getMatrix3(m,b);
// b = [10.0, 14.0, 18.0]
// [11.0, 15.0, 19.0]
// [12.0, 16.0, 20.0]Content copied to clipboard
