[IGSTK-Users] two trackers and RequestSetTransformAndParent

[Ray Tayek]

hi, i think i have two trackers working in the hello world sample and 
i want to see if i am doing this in a reasonable way.

helloworld does a m_GUI->View->RequestSetTransformAndParent( 
identityTransform, tracker );. but the view has only one of these 
delegate things. so looking at the two views sample, he does a:
  tracker->RequestSetTransformAndParent( identityTransform, mesh ); 
and a: m_GUI->m_View3D->RequestSetTransformAndParent( displayTransform, mesh );

it's not clear what doing a RequestSetTransformAndParent does to a 
tracker, but it seems to work (one would think that the transforms in 
the tools would do the right thing).

i ended  up making an axes, placing the cylinder relative to the axes 
and doing a: 
axes->RequestSetTransformAndParent(identityTransform,m_GUI->View); 
and a: tracker->RequestSetTransformAndParent( identityTransform, axes 
); for *both* of my trackers.

this seems to work.

i am on the right track or i am i digging a hole?

thanks
