<p class="MsoNormal">Hi fellow VTK enthusiasts,<o:p></o:p></p>
<p class="MsoNormal">I have what is in essence a 3D graph of vtkCubeSource objects from which I select one at a time, sometimes using the standard vtkPicker approach, sometimes using other mechanisms I’ve coded myself. Whichever mechanism I use to do the picking,
I’ve also coded how I visually highlight/indicate what’s been selected; thus, the red wireframe box that the vtkPicker approach leaves around the picked object is at best irrelevant. However, if I follow a vtkPicker-based pick A with a non-vtkPicker-based
pick B, that red wireframe box remains around picked object A, even though by the internal logic of my application it’s no longer picked.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">That the vtkPicker object thinks it’s still picked doesn’t matter to me – I track picking independently of that – but I can’t figure out how to remove that red wireframe box that is a consequence of the vtkPicker’s “picked” state. I’d
imagine it’s just a wireframe vtkCubeSource or the like and that it would have something to do with the vtkPicker’s vtkActor’s vtkProperty’s bounds (as in picker->GetActor()->GetProperty->GetBounds(bounds), where bounds is an array of 6 floats and picker is
a vtkPicker *), but snooping around in the source code hasn’t gotten me to find where that red bounding box is drawn. Any suggestions on how I can turn it off and just generally access it? Thanks.<o:p></o:p></p>
