[vtkusers] How to interact a scene with a compass

[Paulo José Correia Bernardes]

Hi,

I’m trying to visualize archaeological data using VTK. So far, I’m importing
each object of the excavations plans to a polydata and render them on a
renderwindow. Of course, one important aspect for the archaeologists is to
have the information about the North of the scene. Therefore I have to
represent a compass and I’ using vtkCompassRepresentation and
vtkCompassWidget to represent and interact with a compass. But, what do I
have to do to constantly update the compass position when I rotate the
scene?

Many thanks!

 

Paulo
