[vtkusers] vtkPropPicker not picking

[Jorrit Schaap]

Hi Edi, Will,

I experience hardware picking problems as well. I use an SGI 320 running WinNT, videodriver version 4.1.4, vtk version 3.1.2, vtk source $Revision: 1.539 $, $Date: 2000/06/11

Is there any way to turn off hardware picking until it is fixed?
Or what seems to be the problem? Can I conribute in the debugging?

Greetings, Jorrit
