Playing with Normal Mapping

I just played around a bit with normal map support, and quickly integrated it into CopperCube, as test. irrEdit, the irrlicht editor CopperCube is based on never supported normal maps, although irrlicht did, a thing which always annoyed me.


I was thinking about what types of normal maps to support, and considered only to support Object Space Normal maps, because they are easy to implement on all the targets, are a bit faster to compute on slow devices, and even need less memory. Unfortunately, they are a pain in the ass to create, so I'm now going with tangent space normal maps.
There is a lot of work to be done before it is finally functional, but I'm happy that it sort of works already in the editor now. It's a step into the right direction.
