How would I go about drawing simple 3D shapes in 11.0? [Solved!]

11.0 adds a bunch of new features to be used from shaders for supporting depth buffers, but I don't have any clue how I'd actually use them. Are there any examples out there or something to get me started?

I've been working on trying to get it to work, and I've been making progress. I've been trying to adapt the love3d demos' code to work in my environment.
Doing the calculations outside of the shader code seems to suggest that it
should be drawing something, but it's not.

(The drawn lines are drawn outside of the shader. Note the Z coordinates of the vertices, which seem to be much larger/smaller than they should be.)

After fiddling with my matrix function, I got it to work! I'm not sure what the issue was, but now I've got a 3D triangle.
Also, turns out my calculations seem to have their Y coordinate flipped.

If you want to see how it works, you can visit the GitHub repo:

(Also, sorry for the triple post. I forgot the edit feature was a thing until after I'd already posted....)

Yeah, I did run into that. The makeProper function reorders the matrix.
