Title: More OpenGL questions. Best ways to handle drawing.
Post by: Pixel_Outlaw on October 01, 2007

Question 1
I was wondering about the use of drawing lists.

First what would be the fasest way to draw hundreds of quads with a single texture in various sizes.
-Dynamically
-Gl Lists
-Gl Arrays

Also when drawing these quads dynamically is it better to use scaling to resize the borders or is it just faster to use dynamic variables?

vertex arrays are very fast (and made for that purpose actually).

display lists are an old mechanism.

also if you use a single texture, just bind the texture once, then simply draw multiple quads. Geometry is very fast, texture binding slows it down. So minimize texture binding as much as you can
