I do not come in peace; I am here on a mission. I wish to vanquish the angles and trig which run amok
To my knowledge, this seems to stem from the thought:
The user provides and requests angles, therefore my formulas should input and output angles
At the very least, this is untrue in that the user provides degrees and we compute with radians
But more pervasively, I argue that the formulas are first and foremost Geometric and not Trigonometric

Ultra-compact sprite rendering code with example frame animation logic. This release contains tech bits from the upcoming SuperNeo™ 2D game engine and includes anchor/pivot point, rotation, color filtering, alpha blending and built-in antialiased point sampling. As usual: complete, runnable single-function app. ~150 LOC. No modern C++, OOP or (other) obscuring cruft.
Sprites are rendered back-to-front (AKA "painter's algorithm") in the order they are submitted, as one draw call. The provided setup employs a single texture atlas containing all the sprite graphics.
The renderer is "im

Minimal WASAPI reference implementation. Runnable console application contained in a single function and laid out in a linear, step-by-step fashion. No modern C++ / OOP / obscuring cruft. Produces a steady sine wave sound.
(This is a re-post of the same gist I posted a few years earlier, simply due to me wanting the Minimal D3D11 series to be listed contiguously and it's not possible to hide or rearrange gists).
