mat3.rotate_axis_angle [method]

mat3.rotate_axis_angle( real x, real y, real z, real a[, bool reset ])

generate a rotation matrix (rotation around specified axis) and multiply or set it to this matrix

• if reset is true, the generated matrix is directly set to this matrix
  • otherwise, generated matrix is right-multiplied to this matrix
  • if current matrix is an identity matrix, reset has no effect
