Hi Greg,
hi Peter,
hi Schorsch,
hi Radiance-Fans,
many thanks for your responses. Like you mentioned in your Emails, i will
now use a photon mapping to simulate the behavior of my specific HOE's. I
have written Roland Schregle to get support (I hope he will answer).
Meanwhile, for a first try, i will use prism1/2 or dielectric materials. I
am curious about the results.
Best regards
-Frank
