A 3D Rasterizer For Embedded Devices

Jet is a compact, dependency-free 3D rasterizer written in C++17, designed for memory-limited microcontrollers like the ESP32 and STM32. It runs entirely in software using integer-only arithmetic and 16-bit RGB565 color, making it well suited for SPI displays such as the ST7796 and ILI9488. On an ESP32-S3 it can render around 650 on-screen triangles at 60 FPS or 1300 triangles at 30 FPS on a 480x320 display, with performance roughly between the Sega 32X and Saturn. A Wipeout-style demo video demonstrates its capabilities.
