    • rotateLocal

      public Matrix2f rotateLocal(float angle)
      Pre-multiply a rotation to this matrix by rotating the given amount of radians about the origin.

      The produced rotation will rotate a vector counter-clockwise around the origin.

      If M is this matrix and R the rotation matrix, then the new matrix will be R * M. So when transforming a vector v with the new matrix by using R * M * v, the rotation will be applied last!

      In order to set the matrix to a rotation matrix without pre-multiplying the rotation transformation, use rotation().

      Parameters:
      angle - the angle in radians to rotate about the X axis
      Returns:
      this
