Hi Dženan,
Actually I have the same intention as you. My approach was like that:
osg::Vec3 achse;
if (orientation == Qt::Horizontal) {
achse = osg::Vec3(0.0, 0.0, 1.0);
} else {
achse = osg::Vec3(1.0, 0.0, 0.0);
}
osg::Matrixd myRotationMatrix;
myRotationMatrix.makeRotate(osg::DegreesToRadians((float)newValue),
achse);
view->getCameraManipulator()->setByMatrix(trackballMatrix *
myRotationMatrix);
Unfortunately this just rotates the model arround its origin. And I don't know
how to change it the way I need.
I guess I have to do some "translate * rotate * translate" sequence.
Maybe there is someone out there who can help.
