ProtoTracer: 3D Rendering and Animation Engine

This project is a live 3D rendering and animation engine designed for use on microcontrollers.


As a quick way to showcase the capabilities of this software, here is a demo showing a live rendering of a rotating and textured .OBJ file:


  • 32-bit FPU
  • 200MHz+ processor
  • At least 80KB dynamic memory

This codebase has been tested on an Arduino Mega (smaller .OBJ file with a 89 pixel matrix) and on a Teensy 4.0 (2000 triangle scene with a 2,804 pixel matrix).


The following links give a detailed description on how to import files, set up controllers, manipulate objects, and render to displays:
