I just started working in MonoGame with 3D code. I've used OpenGL before in the past, and I've also built engines with 2D Sprites/SpriteBatch's in MonoGame.
However, I'm getting extremely stumped with going from GL to XNA, likely due to the fact that I believe XNA is no longer a "state" machine like GL is.
I've looked thru the tutorials by RB Whitaker and Riemers -- but most of the stuff they have written covers models, etc. I've already migrated some of my code to build procedural meshes into a VertexBuffer. I'd like to test it now, but I'm getting very confused as to how to setup the World, View, Projection matrices, etc.
Are there any good tutorials that either show how to move from GL to XNA -- or optionally -- any good tutorials that assume you're not using Models, etc? I'm looking to write something fairly low-level when it comes to primitives.
