Subject: [vtkusers] Problems with vtkPropPicker + OpenGL2

Hello,

I am experiencing problems with vtkPropPicker when using OpenGL2 backend
(Java bindings). I have attached a screenshot of an example setup with two
surfaces. vtkPropPicker very often returns a wrong prop - red dots on the
surfaces mark approximate places, where the reading returned the other
surface, not the expeced one. As you see, this happens all over the place,
both on the top and bottom surface.

Those problems do not occur when using vtkPropPicker with the old OpenGL
backend. There is also no such issues when using vtkCellPicker and OpenGL2.

Do you know of any problems with Picking + OpenGL2 that could be the reason
for such behavior? If not, I would be happy to provide more information to
find the cause of this problem

Regards,

Marcin
