ProtoTracer: 3D Rendering and Animation Engine

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

Demonstration:

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:

Recommended platform requirements:

• 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).

Usage:

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

• Creating a controller
• Using an existing controller
• Creating an animation
  • Adding (.OBJ) objects with UV maps
  • Adding (.FBX) objects with blend shapes
  • Adding image materials
  • Adding gif materials
  • Creating a shader material
  • Modifying 3D objects
  • Keyframing animations
