Hello,
I hope this qualifies as advanced.
To calculate a CGH (computergenerated hologram) I need to create a
pattern which consists of the sum of several translated onion patterns
squared. How can I accomplish this? Layered textures obviously won't do
the trick.
Using an Isosurface function as the pattern would be perfect. Does that
work, and if so how?
Cheers,
Daniel
