rotatedZ method

Matrix4 rotatedZ(double radians)

Returns this multiplied by a rotation of radians around the z axis. Note the order.

Implementation

Matrix4 rotatedZ(double radians) {
  final c = math.cos(radians);
  final s = math.sin(radians);

  return .new(
    // dart format off
    (this[0] * c) + (this[4] * s),
    (this[1] * c) + (this[5] * s),
    (this[2] * c) + (this[6] * s),
    (this[3] * c) + (this[7] * s),
    (this[0] * -s) + (this[4] * c),
    (this[1] * -s) + (this[5] * c),
    (this[2] * -s) + (this[6] * c),
    (this[3] * -s) + (this[7] * c),
    this[8],  this[9],  this[10], this[11],
    this[12], this[13], this[14], this[15],
    // dart format on
  );
