I'll emphasize that I am very new to graphics programming. I've been using XNA up until now and I've been looking for a way to build simple 2D functionality with textured quads. I'm sort of starting to get how the whole process works, but the idea of positioning things from 0 to 1 doesn't seem quite right for what I'm doing. Is this the only way to do it? I've learned that I'm supposed to be rendering quads to an orthogonal projection, but I guess my problem is exactly how to implement that the correct way.
I totally acknowledge that my problems are a result of not understanding the technology, but all of the tutorials I can find tend to gloss over a lot of the details. Is there a simple way to set up an orthogonal projection in d3d11, and is there a simple way to convert the coordinates so I can specify it in pixels (like the XNA spritebatch)? I'm hoping that seeing the answer to this will help me get a more solid grasp on a lot of the areas where I'm confused in general with graphics programming.
