Hello, I´m building a particle system and I would like to know what is better today to use fi Point Sprites or Billboards. Billboards in much less efficient than Point Sprites (you need to send 4 verts to the card for every particle),and Point Sprites are not supported by all cards but it is the thing to use. Any suggestion? Thanks in Advance. HexDump.

Well, it partly depends on what kind of particle effects you want to use. If you want to be able to streak particles (like sparks), it might be better if you use billboards. If you are only going to do effects that require rounder particles, then use pointsprites. Also, there is one limitation of pointsprites that isn''t mentioned often - if there is no hardware acceleration, the pointsprites will reach a maximum size of 50 pixels on the screen (at least they do on my Rage Fury Pro card).
