[IGSTK-Users] How to represent a GroupObject ?

[Patrick Cheng]

Hi Sophie,

1. Is m_Point an EllipsoidSpatialObject?

2. Right now EllipsoidRepresentation class assume it takes only one 
single SptialObject, not a group of objects. What you can do is to make 
a GroupEllipsoidRepresentation class. Then, around line 112 in 
igstkEllipsoidRepresentation.cxx class, loop through the GroupObject 
tree to generate the VTK actor for every single object.

Let me know if this works for you.
