Background
I needed code with no dependencies to model the legs of a walking robot. "Spot" style creatures like from Boston Dynamics are very popular these days.
I prototype in perl, but my robot is likely to use C (on Arduino) or maybe circuit-python - undecided as yet - but that's the reason for the "no dependencies" requirement of course. Either way, there was plenty of *math* everywhere showing how to do what I need, but no actual *code* I could find (besides one confused stackexchange student question in Javascript).
Hopefully this can help everyone who needs to rotate things around in 3D...
