So far I managed to create three different effects:
- star tunnel: just round position generator + position update
- attractors: four attractors that affect acceleration of each particle
- fountain: simple collision detection with a floor
Let us see some of the results...

Plans
- Create more effects! This will make my system more reusable. I often see particle tutorials that are very simple and cannot be easily extended. My idea is to have decent amount of flexibility.
- Optimize!
- I have rough numbers about the system: 250k particles (in the attractor effect) take around 13ms to calculate (on CPU). Fps drops to 30fps.
- It would be nice to create a million particle system and run it at 30fps at least. I target CPU, not GPU currently
- Test several methods of drawing and updating GPU buffers.
I do not want to set any deadlines by now. Hopefully there will be some more interesting posts about this experiments in near future :)
