Why would editing the position of points in space ever be slow? Moving a single vertex is going to be cheap.

So yeah, not open source.

And the Enterprise plan isn't the non-profit/education one.

I was recently trying to render a math visualization for a very large search space and fell into the map tiling rabbit hole. The idea was to randomly sample the viewport then pan/zoom to guide the search. OpenSeadragon was the only solution I got working, but it wanted the zoom pyramid prerendered and aggressively cached, so nothing updated. I don’t need the vector editor, so I’m tempted to port lightning to OpenSeadragon.
