Hi,

What is Post-processing?
please help.

So Thanks.

"Post-Processing" is screen-shader.
i mean like a Bloom effect or a Depht of Field Effect.

post processing means;

you know you get a image on the screen when engine renders objects, this image is actually a 2d image. Bacuse that you process this image AFTER engine renders everything and creates the image, it's called post-processing.

you take this image, and run some sort of shader algorithms on it and you get a processed with your shader.

anybody know any good source about it?(sites,blogs,....)

This might help you...
