Projection Information

The keywords PROJ_VEC_U1 to PROJ_VEC_U6, contain the vector along the u-axis for each projection plane. The keywords PROJ_VEC_W1 to PROJ_VEC_W6, contain the vector perpendicular to each projection plane.
Note: When giving the projection vectors, the u-vector is primary and the given w-vector adapts to this. If you expect the w-vector to be primary, make sure the v-vector is in the view plane defined by w-vector!
