An elaboration on Minimal D3D11 pt2, adding shadowmapping and incorporating various improvements and alternative approaches to the rendering setup, such as manual vertex fetching, samplerless texture lookup, null shader depth map rendering and procedurally generated texture and [instance data](https://gist.github.com/d7samurai/abab8a580d0298cb2f34a44eec41d39d#file-shader
Follow-up to Minimal D3D11, adding instanced rendering. As before: An uncluttered Direct3D 11 setup & basic rendering primer / API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion. No modern C++ / OOP / obscuring cruft.
The main difference here is that the hollow cube is rendered using instancing (which saves a lot of vertices compared to the original, so geometry data is now small enough to be included in the source without being too much in the way), but also all trigonometry and matrix math is moved to the vertex shader, further simplifying the main code.
In this case, each instance is merely this piece of geometry, consisting of 4 triangles:
