Detailed Description

The SoTrackballManip wraps an SoTrackballDragger for convenience.

trackball.png

The manipulator class takes care of wrapping up the SoTrackballDragger in a simple and convenient API for the application programmer, making it automatically surround the geometry it influences and taking care of the book-keeping routines for it's interaction with the relevant fields of an SoTransformation node.

Here's a dead simple, stand-alone example on how to set up an SoTrackballManip in a scenegraph:

  #include <Inventor/Qt/SoQt.h>
  #include <Inventor/Qt/viewers/SoQtExaminerViewer.h>
  #include <Inventor/nodes/SoCone.h>
  #include <Inventor/nodes/SoSeparator.h>
  #include <Inventor/manips/SoTrackballManip.h>
      
  int
  main(int argc, char* argv[])
  {
    QWidget * mainwin = SoQt::init(argv[0]);
  
    SoSeparator * root = new SoSeparator;
    root->ref();
  
    SoTrackballManip * manip = new SoTrackballManip;
    root->addChild(manip);
  
    root->addChild(new SoCone);
      
    SoQtExaminerViewer * viewer = new SoQtExaminerViewer(mainwin);
    viewer->setSceneGraph(root);
      
    SoQt::show(mainwin);
    SoQt::mainLoop();
  
    root->unref();
      
    return 0;
  }

Compile and hit 'ESC' to go into scenegraph interaction mode in the examinerviewer, then change the rotation of the cone by interacting with the dragger bands.

SoTrackballManip::~SoTrackballManip ( ) [protected]

Destructor.
