General Configurations:
# Development Platform: Visual C++ 2008, Debug+Release build
# Used OpenFrameworks library
# Graphics Hardware: ATI Mobility Radeon HD 3470 (OpenGL 2.1)
Basic Particles Results:
Animating view aligned particles
More Particles:
***Update Point Sprites working in the Linux build
Discussion:
Dynamics: Each particles generates with a random direction from a source position and shoots out with some
gravitational pull, as the gravitational pull increases in time, they are pull back towards the source. Each particle
also has a random lifetime of [0,10] seconds, after which they regenerate from source.
The texture for the particles is a square image, but only a circle has been drawn from the center, other
parts were made transparent, and a blend function was used make the parts outside of the circle transparent.
I finally got point sprites working after building my project on linux, the same code fails (to send texture
coordinates to the fragment program) in Windows, which I have strong reasons to believe to be a ATI driver issue.
