here is a quick fraps capture showing some integrated physics (bullet flash*) and some post processes
post processes are pretty easy to implement but I am still looking to make them chainable so they can be used together.
have got some simple ones like invert, sepia… and some more complex ones like convolutions and depth of field as well as DOF with depth based bleed reduction which works quite well.
materials work by stacking various techniques together such as texture, fog, rim, reflection, refraction, diffuse..etc. which makes building the materials really quick! also supports a few blend modes for blending these techniques.
