I finally brought my postFX plugin to a (hopefully) stable state!
I first wanted to integrate this functionality into the Maratis main engine but decided to make a modular and customizable plugin instead.

You can find it here: http://scary-squid.de/en/show-product.p … processing

You can operate the plugin completely with LUA code so no C++ needed to use it (well, you still have to compile the plugin).
There is a small glsl shader shipped with it which showcases some features. It is more or less a fast hack though.

Keybinding for the demo:

Up & Down arrow: More bloom & less bloom
Left & Right arrow: Bigger radial blur sample distance & smaller radial blur sample distance

Numpad 1: Bloom shader
Numpad 2: Radial blur shader

Have fun!
