The engine could be using .obj files in addition to code for creating models/scenes.

[marc-q]

When adding support for .obj files, the engine could also be used for multiple scenes without having a lot of code and to recompile it for each change in the scene. It also would make it possible to share scenes/models.

But i still want to use planes (4 vectors) as surfaces. This means that instead of 3 there will be 4 vectors for each face inside the .obj file.
