Hi, I’m playing with a kind of particle system thingy… and have a few questions:
What is the fastest way of drawing thousands of small triangles (about pixel size or a little bigger). Display lists ? Or just straight glBegin(GL_TRIANGLES) stuff ?
Display list are faster then using a bunch of glbegin/glend’s, but if the triangle is the size of a pixel, you are not going to be able to tell it is a triangle.
Then make a display list of points instead.
Yes you can do billboarding in opengl. Billboarding is not a function, but a style of drawing objects to reduce polygon count.

Is there “billboarding” in OpenGL ??
Thanks in advance,
