From the Viewer header file...
/** Execute a main frame loop.
* Equivalent to while (!viewer.done()) viewer.frame();
* Also calls realize() if the viewer is not already realized,
* and installs trackball manipulator if one is not already assigned.
*/
virtual int run();
If you don't want a TrackballManipulator, you'll need to *not* use
Viewer::run().

Hi,
I want to set the modelview matrix with
viewer.getCamera()->setViewMatrix(modelViewMatrix) like in the
following code:
int main(int argc, char **argv)
{
osgViewer::Viewer viewer;
osg::Node* rootNode = createRootNode();
viewer.setSceneData(rootNode);
return viewer.run();
}
Later, in an osg::NodeCallback, I perform:
viewer.getCamera()->setViewMatrix(modelViewMatrix);
But the modelview matrix isn't modified at all.
On the other hand,
viewer.getCamera()->setProjectionMatrix(projectionMatrix) seems to
work.
What should I do to the viewer in order for setViewMatrix() to work?
Thank you!
Cheers,
Juan
