Hello.
I am computing the veritces of a quad in such a way that the quad will always face the camera.
Would it be possible to use a vertex program for this?
As you probably assume I know nothing about vertex programs, so if it is possible, a detailed description would be very appreciated!
Thanks for your time.
hmmmmm.
Do you suppose it will be faster?
I don’t want to be a pest, but my idea was that if I knew that the vertex program-approach would not really increase my fps, than I would focus on different parts of the program rather than learning Cg now without any real use for me (yet).
Thanks for the reply
CG is prety easy for beginning & results are whole lot better. Only minus is that you need T&L card. Not sure about performace yet, although, a lot of work is moved to GPU instead of CPU, so - parallel performance.
Works on my GF2GTS, I even can run NV30 demos with emu. And current non-beta compiler should support fr programs too.
Yes there is serious problems with server, unfortunately as often
Just downloaded CG final. There are some pure OGL demos. CG is easier & have optimizing compiler to make all the stuff faster (I hope so, havn’t checked out).
