getting things to always face camera

Recommended Posts

i'm not looking for code. i'm writing a desktop enviroment for linux, but i'm working on a particle engine for it at the moment, so far it works great, slowly adding features to it. now i am looking for a direction to search for to get each particle facing the camera at all times.

well i saw that, and the books that i have on opengl says billboarding will make the size be the same no matter how far an object is away. maybe that's just an ability of it. i guess i will have to look into it further unless someone else posts something. thanks for the input though.

Billboarding has nothing to do with size, it's only purpose is to keep a polygon oriented towards the camera. Billboarding is exactly what you are looking for.

See this article for more information.
