Well, I'm the kind of person who likes to make things from scratch so I was thinking maybe information about how it all works, but if using a library to start with is better, then I could go with that. If that's the case though, then which one would be the best?

Well, it depends on what platform and hardware you want to use. Making a hardware accelerated API that runs on PCs with modern graphics cards would be *very* hard, but a software rendering library is quite doable.

Well, if I did anything 3D by myself, it'd be in C# for now, and therefore .NET based. I guess I could use XNA, but that would just help me learn 3D in XNA, not how a renderer works (or would it?).

So I guess I'm asking if there's any good documentation on 3D rendering in general or, if it'd be easier, for XNA.

Well, you want to read some DirectX tutorials (or OpenGL if you want to use that, but I don't know if XNA supports it). Basically, you will be calling functions which send the individual polygons to the video card for rendering.

Could you point me in the right direction? I haven't had much luck by myself.
