Hello guys,
Anybody give me some suggestion to improve the performance of my drawing? Or give me some reference
thanks,
Wenhui
Have you tried a wider pencil?
Seriously, if you want any sensible replies you will have to give a lot more detailed information on how you’re currently drawing things.
First have a read here for basics :
http://www.opengl.org/wiki/Performance
Then for more precise help, as said Lord crc, you will indeed have to give details about your hardware gpu/vram/cpu/ram/OS, how you draw things, what you draw, what rendering speed you expect, etc.
Rule of thumb: Keep the GPU always busy 
Minimize redundant state changes.
Batch geometry that share the same textures and shaders or rendering states
Use triangle strips whenever possible.
Use indexing
Use only VBOs
Triangle strips are not that good. Try simple indexed triangles with vertices in “hilbert curve” order instead, takes advantage of any size of vertex cache.
Thanks, guys
And another powerful tool: use display list as possible as you can.
