<div dir="ltr">Hello<div><br></div><div>I have rendered a vtkVolume with a vtkInteractorStyleTrackballActor Interactor.</div><div><br></div><div>I have also implemented a slider to allow the user to alter the opacity of the displayed volume. </div>
<div><br></div><div>Unfortunately if the opacity is changed to be too low, the interactor seems to stop working ( ir you can no longer rotate, pan, etc). If you raise the opacity it starts working again.</div><div><br></div>
<div>any ideas whats going on here?</div><div><br></div><div>cheers</div><div>Perryn<br clear="all"><div><br></div></div></div>
