particles

Specifically I'm talking about particles as seen (for example) in the UE4 dev video here. They're not just points and seem to have a nice shape to them that seems to follow their movement.

Is it possible to create these kinds of particles (efficiently) completely on the GPU (perhaps through something like motion? Or is the only (or most efficient) way to just create a small particle texture and render small quads for each particle?

I'm trying out modifications to the following particle system. http://create.msdn.com/en-US/education/catalog/sample/particle_3d I have a function such that when I press Space, all the particles have their positions and velocities set to 0. for (int i = 0; i < particles.GetLength(0); i++) {… >>> More
How to render 2D particles as fluid?

Suppose you have a nice way to move your 2D particles in order to simulate a fluid (like water). Any ideas on how to render it? This is for a 2D game, where the perspective is from the side, like this. The water will be contained in boxes that can be broken in order to let it fall down and interact… >>> More
Drawing particles as a smooth blob

as seen on Game Development - Search for 'Game Development'
I'm new to game/graphics development and I'm playing around with particles (in 2D). I want to draw particles close to each other as a blob, just as liquid/water. I do not want to draw big circles overlapping as the blob won't be smooth (and too big). I don't really know physics but I assume what I… >>> More

I'm not talking about the background grid here, I'm talking about the swirly particles going around the Gravity Wells! I've always liked the effect and decided it'd be a fun experiment to replicate it, I know GW uses Hooke's law all over the place, but I don't think the Particle-to-Well effect is… >>> More
Fastest Strategy for Drawing Flash Particles

as seen on Stack Overflow - Search for 'Stack Overflow'
I am wondering what the fastest approach might be for using Flash/AS3 to render a 2D point plot (sonar lofargram) ; basically screens full of tiny 2D dots using Flash as fast as possible. Any suggestions on where to start? Is Flash capable of displaying 10's of thousands of 2D points (or more) with… >>> More
