I have for example the idea to generate some terrain scene using libnoise and directx and I think that I at least would have to compile a dll for libnoise, would that be allowed? I hope that fx files are allowed too? If I understand the explanation right all that is allowed, I just want to be sure...
it would be great if it were possible to create an empty model in the engine which then could be filled with a mesh buffer generated by code. as far as i know this isn't possible at the moment?
using directx to draw your own geometry somehow defeats the purpose of a game engine.
