[vtkusers] the sphere not be dsiplayed with the vvtkboxwidget

[Eric E. Monson]

Hey Ali,

Hmm... I don't know anything about the .NET setup, but it seems strange that it would have a vtkBoxWidget2 and not a vtkBoxRepresentation... Maybe with your .NET you are limited to a much older version of VTK?

Anyway, if that really doesn't exist, then you may have to use the older vtkBoxWidget instead. There are a few examples which are all pretty similar to each other. Check out the vtkBoxWidget doxygen page:

http://www.vtk.org/doc/nightly/html/classvtkBoxWidget.html

and look under Examples and Tests at the end of the Detailed Description. In the VTK source there is /Examples/Tutorial/Step6/Cxx/BoxWidget.cxx which displays both a cone and a box widget simultaneously. 

Talk to you later,
-Eric
