Hey srinu,

My card does support the aforementioned extension, but I get no fountain...occasionally I can see some VERY tiny particles where a fountain might be (center of the plane), but nothing more than that. Sorry!

Hope that helps,
Aviosity

NOTE: Just a friendly tip, but something like this probably belongs in "Your Announcements". Normally you'll want to be asking a question or help with a problem in the OpenGL forum :).

All I can see is a purple floor and a few pixel sized particles.

Edit: I'm using a 6600gt. Is that an ATI specific extension?

hello everyone,
srinu here........... i use a ATI FireGL V 3100 graphics card. i got similar responses from my friends also. most of them can only see small particles but actually particles are of heart shaped.

will the problem be solved if i use QUADS instead of GL_ARB_POINT_PARAMETERS.

plz help me out in fixing this bug. i am ready to share the source code.

Thanks & Regards,

Srinu

A FireGL probably has far more attention paid to the point sprites implementation than on the regular consumer cards. So yeah, you might want to consider quads instead.

I just tested it out on my laptop with a mobility FireGL V3200. As expected, everyhting is functioning perfectly. From the data in this thread, it appears that this extension is only supported on ATi cards or workstation cards. Textured quads would probably be the best choice.
