Definition

Sets *mat_ptr to a rotation matrix for the given angle of rotation for the given axis.


Returns

SE_DRM_STAT_CODE_SUCCESS and *mat_ptr is set appropriately, if valid parameters were passed in.
SE_DRM_STAT_CODE_NULL_REQUIRED_PARAMETER and no changes are made, if
  1. mat_ptr is NULL, or
  2. axis == SE_LSRAXIS_AXIS_REFERENCE_VECTOR and vec_ptr is NULL.
SE_DRM_STAT_CODE_FAILURE and no changes are made, if axis is not a valid, single axis (U, V, or W).

Parameters Notes

1 pointer to the matrix to be set

2 if axis == SE_LSRAXIS_AXIS_REFERENCE_VECTOR, this vector is used to specify the axis of rotation

3 identifies the axis around which we're rotating

4 the angle of rotation, in radians
