Hello, thanks for your fast reply!
In fact I am an optics enthusiast. With more faces I could simulate variations on consecrated designs as LITTROW, PELLIN-BROCA, BREWSTER, BAUERNFEIND, DOVE, Pentagon, Rhomboid prisms. I have been constructing some devices like telescopes and rearprojection.
Therefor the angles should be individually settable. Intensity is not a must, but would be nice (if possible). ;)
Please let me know if you need further information.
