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
