[IGSTK-Users] ObjectRepresentation lost when displaying it

[Vincent Gratsac]

Hi igstk-users !

I noticed in many IGSTK Examples that for adding an object 
representation to display, there is one method per object type.
I mean that we can find methods called AddCylinder() and AddEllipsoid() 
in OneViewAndTracking example for instance.

This is due to the fact that we have to Copy the representation before 
adding it to display. Why this copy is required ?

In my application, if I do not copy object representations, then only 
the last one will be shown.

Must I write as many methods as objects types used, in order to copy 
them before adding?
Could someone help me to understand ?

Thank you and have a nice day,
