Can you explain what you mean by this? How did you go about it?

He draws it multiple times with transparency?. Walla, multipass. I really hate that buzz word.

What do you mean by this?

it means you can simulate post processing manipulating pixels of some render target. You 'save' your screen shot to a texture, manipulate it and then put it on the screen(screen quad). Aint i right?
getPixel and setPixel...
I havent test it, but i think this also can work directly on screen without render targets.

I'm aware of that, and you'd do it in a shader with tex2D (in HLSL anyways). My inquiry was as to what sio2 meant by a multi-pass material besides the render target route.
