Rendering the Illusion

epubli, 2026

In the early 1990s, home computers lacked the processing power to render true, three-dimensional worlds. Yet, games like Wolfenstein 3D and Doom managed to create incredibly fast, immersive 3D environments that ran flawlessly on basic hardware. The secret was not a hardware revolution, but a brilliant mathematical optical illusion programmed by John Carmack: Raycasting. This technical history book breaks down the elegant algorithms behind the Doom engine. It explains how raycasting works by projecting invisible lines from the player's viewpoint across a 2D grid, calculating distances, and drawing vertical slices of textures to fake depth and perspective. The narrative celebrates the era of extreme software optimization, where developers had to use profound mathematical shortcuts to bypass hardware limitations. Step into the brilliant code that defined a generation of gaming. Discover how a single mathematical trick tricked our brains into seeing 3D, birthed the first-person shooter genre, and laid the algorithmic foundation for the entire modern video game industry.
