yes, I would like it to bulge up in the middle... I've never worked with
Bezier patches, but judging from the documentation it might be possible, if
I could figure out how to make the edges curved in such a way that they

for now and get to that when I have somewhat more time to figure out all the
necessary calculations...
thnx for the info
