Hey , Basically I want to create some sort of wave effect on my screen to signal lets say a huge explosion. Mind you I am not talking of a camera shake effect. More like as if there were ripples moving across the screen. I have seen such effects in games before but I don't have any references now. Could any one give me any pointers? Anything at all would be much appreciated. Sorry for being so vague.

Hey there,

Do you want to do in 3d or 2d? I came across this thread:

http://www.gamedev.net/community/forums/topic.asp?topic_id=557515

and they discuss some heat wave in 2D. Now, for ripple, I would image it bases on the same principle, just different math function. Uhm, or, you could look up a water ripple demo, and somehow use that effect for a post processing algo that center on your explosion. Anyway, if you can find some reference that would be great.

Thanks for the reply.

I am looking to do that effect in 3d. I got a video of what I would like to do.

Hope this makes my question more coherent.

That actually looks like a 2d effect on a picture of a 3d scene, not a 3d effect.
You could do that by rendering to a texture, and then rendering that texture with a shader (which performs this effect) to the screen.

Oh right. I was just saying that the game itself is 3d.

Anyway could anyone give me any reference to such a shader?
