View Full Version : Texture that always faces to the viewer?

I´m talking about these 2D textures, that spin with, if you move arround them, so that you allways see the front of it.
Many games use it and I want to use it for a particle system ... but I dunno how this technique is called and how I can code this in OpenGL?

That method is called billboarding. Search the forum for billboards and you should find what you are looking for.

Your "Up" vector (mat,mat,mat)
Your "Right" vector (mat,mat,mat)
Use those to compase a quad and you're done. http://www.opengl.org/discussion_boards/ubb/smile.gif
Look also on NAte Miller's web site for some implementation sample.
