So, it sounds like you're not populating a vtkSelection with your results, so you may want to try calling Initialize() on your picker, which clears out its list of actors and prop3ds. Otherwise, vtkAbstractPicker has an InitializePickList(), which clears out its vtkPropCollection...</div><div><br></div><div>Talk to you later,</div><div>-Eric</div><div><br></div><div><br><div><div>On Aug 23, 2011, at 1:42 PM, Steven Chall wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Hi fellow VTK enthusiasts,<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">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></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">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?
