Thanks, I removed the separate call to load three.js and the error is gone.

`Entity.setObject3D` was called with an object that was not an instance of THREE.Object3D.

Thanks for your quick reply. That was my conjecture too and I tried it in another sandbox at https://codesandbox.io/s/quirky-sun-y1no3?file=/src/Graph.js - but the problem remains.

Getting wrong type of multivector

Attached is a version that does _not_ produce excess terms by avoiding any use of math. From my other experiments it seems that excess terms are produced as soon as...
