Re: [osg-users] Disable the Mouse default event in osg
Hi,
... Thanks for reply..
If i comment the manipulator then data is not displaying. I m using code...
...
...
lasGeometry-setVertexArray( lasVertices);
lasGeometry-setColorArray(colors);
lasGeometry-setColorBinding(osg::Geometry::BIND_PER_VERTEX);
lasGeometry-addPrimitiveSet(lasPrimitive);
root-getOrCreateStateSet()-setMode(GL_LIGHTING, osg::StateAttribute::OFF);
//viewer.setCameraManipulator(new osgGA::TrackballManipulator());
viewer.setSceneData( root );
viewer.addEventHandler(new osgViewer::StatsHandler);
viewer.addEventHandler(new osgViewer::WindowSizeHandler);
viewer.realize();
while( !viewer.done() )
{
viewer.frame();
}
...
.
And is there any osg functions that i can directly for rotate pan and zoom
buttons.
Thank you!
Cheers,
Lalit

That's because your camera isn't positioned properly which means it's not actually looking at the object. You have to setup the camera view matrix accordingly to your requirements. /ulrich ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Lalit, If i comment the manipulator then data is not displaying. When you don't use a camera manipulator, you should take care of the the view matrix of the viewer. You can use something like viewer.getCamera()-setViewMatrixAsLookAt(eye, center, up); For more information about this function, google gluLookAt.

[osg-users] Disable the Mouse default event in osg
Hi, ... I am new in OpenSceneGraph. I want to disable the mouse event and use these event (Rotate, Zoom, Pan ) in separate buttons. Thank you!

What do you mean 'disable the mouse event'? If you don't attach a manipulator then no events will be processed. You can then control the camera view matrix externally via GUI buttons.
