JB, John thanks for your responses.
yep, that's what I'm trying to do. I fiddled about with a modified
/Examples/VisualizationAlgorithms/Tcl/TransformTextureCoords.tcl
to experiment with a vtkCubeSource, but it appears I'll have to implement
vtkTextureMapToCube. I'm trying to develop a corner orientation marker to
make vtkPVAxesWidget more general: e.g.,
currently there is
vtkPVAxesActor axesActor
vtkPVAxesWidget widget
widget SetAxesActor axesActor
but what I envision is
vtkCubeOrientationActor cubeOrienter
vtkOrientationMarkerWidget widget
widget SetOrientationMarker cubeOrienter
or,
vtkAxesOrientationActor axesOrienter
widget SetOrientationMarker axesOrienter
I'll keep tinkering...(unless someone on VolView
wants to give me a hint :)
