Vtk is fine as long as you’re trying to build a visualization that looks like the ones Vtk anticipates you wanting. It becomes a pain when you want to draw things Vtk doesn’t expect. I do not recommend trying to embed it with complex Qt widgets, for instance, and it’s much better for surfaces and volumes than it is for abstract data.
