A 3D Renderer on an ESP32 With No GPU and No Excuses
Eric (@0015) has released a3d, a software 3D renderer for ESP32 that works as both an ESP-IDF component and an Arduino library. A display is five function pointers. Threading is one interface. There is no PBR, no shadows, no alpha blending — and the benchmark numbers came from device logs rather than estimates.
