Technically there is no distinction between "post-processing shaders" and "object shaders". And even on a conceptual base this distinction can be obstructive.

Hmm, with object-shaders I mean shaders which are run for each pixel drawn of an object, like a common normalmapping shader. For this case, it could be that the same pixel gets attribution from more than one object, if the objects cover that very pixel, but have different depths. With post-processing shaders I meant shaders that work on a G-Buffer or general screen-space bitmaps (like the already rendered image) and are not driven by the actual scene geometry.

But that's the point: shaders always work with geometry ("run[s] for each pixel drawn of an object") and never directly on a bitmap buffer. How would you f.i. categorize the light accumulation pass of a light pre-pass/deferred renderer, where you render bounding geometry (probably low-poly spheres) for your lights and project your G-Buffer content on it to do the lighting calculations in screen-space?
What you call a "post-processing effect" is not more than rendering a full-screen quad and projecting some buffer content and it. But you can achieve the very same effect with arbitrary geometry f.i. bounding geometry to mask certain parts of the scene.
I don't say that it is essentially wrong to speak of "pp-effects", but as a not-so-experienced graphics programmer this distinction can easily lead to wrong assumptions about how a described multi-pass technique actually works.

Just stumbled over this

Pretty awesome technique to get rid of shadow acne!
Needs a little extra work for a deferred environment though, as you can't really use the "high quality" normalmapped normals from the gbuffer

Works out of the box in forward shading though and is a nice improvement to A8's PSSM shadows.

would be fine for A8 as its pssm shadows are so ugly in several cases, especially when camera is used freely... and in anther engine I got so smooth and fast ones together with deferred rendering...

Argh, there you are you nasty litte poster! :\
Anyway, thx for posting. Btw, I've updated my post too in the meantime.

more stuff

thanks!

update time

Thank you. This list is awesome!
