[vtkusers] Question about center,position and origin ?

[Ashika Umanga Umagiliya]

Greetings all,

I am little confused with the coordinates in VTK.

As for my understanding, "GetCenter()" gives the object coordinate  as
shown in following picture :

Whats the relationship between coordinates from "GetCenter()" and
coordinates from "GetPosition()" ?
What is the relationship between above two and "GetOrigin()". Does
"GetOrigin()" returns coordinates in actors local-coordinate system ?


thanks in advance
