[vtkusers] HELP with vtkVolumePicker error

[Dora Szasz]

Hello,

I have tried the VolumePicker.tcl and VolumePickerCrop.tcl example provided in the Examples part, but a strange error appeared: "invalid command name "vtkVolumePicker" while executing "vtkVolumePicker picker" -line 154. Actually is the line where the picker object is declared.

Any other example works, so I have made the wrapping Tcl part, but I don't know what is the problem with this class.

Can you please help me?

Thank you!
