Engine/Game
Why it's bad


storing world space positions in gbuffer
STALKER, F.E.A.R.
Depth buffer can be used to derive position saving a lot of memory bandwidth


uploaded texture upside down
Various engines, mostly Quake derived.
Difficult to debug with tools like apitrace, nsight, pix, renderdoc, etc

    Grammar of Kitten

This is an annotated EBNF grammar of the latest rewrite of Kitten. Items marked with a dagger (†) are explained in the surrounding prose, not in EBNF.
