I was wondering how various effect's were done in games, partticularly directx. In the game EvE Online for example, how would they do the thruster effects and wormhole effects?:

For wormhole, looks like a post-process manipulation like distortion.

And for the other one, it looks like a glare-wind generation. It's quite simple: The output of the bright-pass section must contain these flames of spaceship. If you perform a blur operation along a down vector, then blend it with the original frame, you can get a result like it. Masaki Kawase shows how to deal with generating glare winds.
