Would it be a pain to implement cell selection in HardwareSelector? Maybe you could suggest some key points and locations. I was looking to the current source code for a while but still could not get to the root.
I have polyData with cells. Cells are grouped via additional field data (let’s call it faceId). Usually, there are up to 100 faces for an object. If a user clicks on an image, I need to determine faceId of the clicked cell. I have done it with vtkCellPicker, but it is painfully slow.
Or, would it be feasible to create a separate actor for every face and use HardwareSelector on them instead?
