I am working on a STL file driven 3D engine for use on the Arduboy.
No idea if this is of any use to anyone, but its there if interested. I have an academic goal in mind of creating a cloud debugging utility that runs on the AVR IoT WG(Atmega4808). I am using this project to vet that work. There is a lot of code related to the matrix multiply operation. This will be optimized, however I need a working unoptimized version for comparison. I want to research the improvements in the debbuger.
