This is driving me crazy… the seems to be nothng on google, redbook, msdn, etc anywhere, just hints at to whats possible in realtime rendering…
I have a strip that I want to…bend halfway through the ordering. I read in real time rendering that if you list the vertex twice the face ordering will swap, sort of allowing you to turn corners with the strip.
I’m attempting to do something like this:
A simple grid:
My strip is formed like this:
However in my application after I use each ‘swap’ vertex the facing seems to swap backwards as well.
Anyone know the proper way of doing this?
