[vtkusers] GetPosition of an actor that belongs to an assembly

[Paul]

Hi Nikos,

The actors position is relative to it's parent in the assembly, which is why
it is always the default
start position.

I get the 'global' position by iterating over the assembly path (don't
forget a stop condition in case
the actor in question has any children) and concatenating the transforms
along the way.

  Hi All

  I want to retrieve the position of an intermediate actor that belong's to
an assembly.

  I am using the GetPosition  method however when I rotate or move the
assembly the GetPosition always return the
  default start position of the intermediate actor. Is there any function
that I can use to get the update position of an intermediate
  actor in an assembly when the assemply position changes or the assembly
rotates.



  Regards


  Nikos
