Hi,
I have
built a scene using Ventuz Professional and I want to generate an alpha mask
referring to a Z-value. The function of the mask should have the following
structure.
if
Z(x,y) > ZM THEN M=0 ELSE M=1
Ventuz Professional
also offers a Key node but I really don’t understand how to use it. Can I put
the depth value of the object of my scene in the Z-buffer and generate an alpha
mask, which changes with a selectable z-value?
Did anybody
ever try to do this?
Thank you very
much for your help in advance
bye
