[IGSTK-Users] Display my first object with QT

[Özgür Güler]

Hi Steve,

you have to build also the scene graph, which describes the spatial
relationship between the objects in your scene. In your case it contains
just a cube and the view.

//identity transform
igstk::Transform transform;
transform.SetToIdentity( igstk::TimeStamp::GetLongestPossibleTime() );

// scene graph
// view3D->cube
cube->RequestSetTransformAndParent( transform, view3D );

Best,
Ozgur
