Hi&Hello.
I was playing with COONS function to achieve patch that has invisible boundary edges.
Masking parameter that controls visibility looks like this:
mask = 4*j3 + 8*j4 + 16*j5 + 32*j6 + 64*j7
where jn = 1 or0
When turning off each edge (j) it works fine but suprisingly when all "j" = 0 patch is still showing all 4 boundary edges (see attached fig.)
Have Anyone idea why?
Thanks
