    I am not sure I understand -- what do you mean by picking
    transparent prop? Can you elaborate a bit more? Post some code to
    illustrate the issue?<br>
    <br>
    If you are picking an opaque actor and then making it transparent
    after the pick, there should be no issues with that.<br>
    Picking something that is not being rendered -- I have never done
    that but I would think you'd have to use a ray casting picker (such
    as cell picker).<br>
    <br>
    vtkPropPicker is faster than cell picker (hw accelerated), but
    doesn't give you tolerance and the prop you are picking must be
    visible. If you can live with that, definitely go with
    vtkPropPicker. <br>
