I’ve been looking over the different picking methods in vtk.js, but I haven’t been able to figure the best way to do fast actor-level picking. I don’t need point or cell picking, but I need more accurate picking than bounding box picking.
In lieu of this kind of picking, I’ve experimented with point picking where I update a text string as I move the mouse around. It looks like the points and actors aren’t sorted, which seems like the most useful choice. Is that right?
