Detailed Description
The SoTrackballManip wraps an SoTrackballDragger for convenience.
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.
