* GPU Particle System
|

* @author flimshaw - Charlie Hoey - http://charliehoey.com
|
||||
*
|
||||
* A simple to use, general purpose GPU system. Particles are spawn-and-forget with
|
||||
* several options available, and do not require monitoring or cleanup after spawning.
|
||||
* Because the paths of all particles are completely deterministic once spawned, the scale
|
||||
* and direction of time is also variable.
|
||||
*
|
||||
* Currently uses a static wrapping perlin noise texture for turbulence, and a small png texture for
|
||||
* particles, but adding support for a particle texture atlas or changing to a different type of turbulence
|
||||
* would be a fairly light day's work.
|
||||
*
|
||||
* Shader and javascript packing code derrived from several Stack Overflow examples.
