I’m working with complex 3D models which I color with a vtkLookupTable, using their point data. This is working just fine, but now I need a way to highlight individual vtkCells by clicking them on the vtkRenderer.
Our current solution is creating a hightlight vtkActor on top of the selected vtkCells, but there’s gotta be a more efficient solution. What I had in mind was being able to change individual vtkCells color to white, yet can’t find the way to do that.
Any idea on how to accomplish this?
Thanks a bunch!
