Where I give less of a technical explanation and more of a slight rant on slowly moving away from big tech/proprietary solutions and modern software. There are some notes on the technical “how”, which are to be taken more as an inspiration than as a tutorial.
Where I briefly explain an old school trick to approximate the exponential function, by abusing the way floating points are represented in memory. The method is known since at least 1999, where it appears in a paper by Nicol Schraudolph.
Where I ramble on about the PlayStation texture affine interpolation and a few bits on how to render a triangle in software. Some hacky code cobbled together for illustration purposes.
Where I document how I started learning about emulation and wrote my first toy model. Codeberg link to the project.
