I thought I read that Quake used GL_EXT_point_parameters for particle effect explosions etc, and GL_ARB_point_parameters should be almost identical to that.
there is an example on using the EXT_point_parameters extension, which is pretty much the same as the ARB version except the functions and tokens are renamed.
I should have known that, but forgot while I was searching.
New question: I got the extension to work as far as making the size of a point shrink based on distance from the camera. But the extension documentation (see link above) seems to suggest you can make points fade colorwise rather than merely shrinking in size.
Anybody know how to do that? I can’t make my points fade no matter what I try.
the fade threshold only works if you also have the multisampling extension, which is basically an SGI-only extension that nobody in the PC world has access to
