opengl es - CollisionEffect iPhone game dev question -


I am interested in information about joining the game collision effect for the iPhone from the perspective of developers, it's the OpenGL ES game It looks like, in which there is a very advanced particle system. The distortion of particles after the surrounding area is not something that I can not understand. What is a good keyword for finding this flow effect for the implementation of OpenGL?

For example:

I think this is not anything difficult If your talk is blasted, the particles are left behind in the form of traces of the "rounded" journey, but when the blast wave hits them, they are away from the center of the explosion with large attenuation , So they slow down very fast though the cool effect :)

edit

Number warping part seen :) it's also easy physics, particles collide with the "field" and after the collision some velocity in the direction of their momentum drag is really high so their movement is too fast.
