The demo is having problems on certain hardware. i have used GL_ARB_point sprites feature of OpenGL.i think this might be compatability issue. actually the particle is heart shaped. could anyone there help me out in fixing this bug.
I recently discovered Sprite Point's too, but I found them very useless, after discovering that the point size is interprated in screen coordinates. This means the spites are the same size no mater how far or near they are. This is ok for some aplications, but most of the time it isn't.
Billboarded quads work better (althoug they are somewhat harder to implement) and are supported on all hardware.
PS: Unfortunatelly I could not run you demo, wine just crushed.

The reason i used point sprites is
1. they will always face the camera.
2. much calculations r involved in displaying the quads.
can anyone plz send the screenshot of the demo so that i can know how it is running, which can help me in fixing the bug.
