// Converts an ArrayBuffer directly to base64, without any intermediate 'convert to string then
// use window.btoa' step. According to my tests, this appears to be a faster approach:

Minimal D3D11 elaborations I

A spin-off from the mainline Minimal D3D11 series, adding two-lane 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 itself 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, simplifying the main code (and not needing math.h).

In this case, each instance is mere

Minimal D3D11 sprite renderer

Minimal D3D11 sprite renderer: basic back-to-front sprite rendering reference code with example sprite sheet animation logic. As usual: Complete, runnable single-function app. No modern C++ / OOP / obscuring cruft.

Swap out the sprite sheet with a font atlas for a lightweight GUI / text renderer. Clip individual sprites and glyphs by offsetting screenPos and atlasPos to top left corner of visible area and adjusting size accordingly (all values in pixels):

sprite.screenPos.x += 17;
sprite.screenPos.y += 10;
