Re: [osg-users] current View Point
i have two viewers and put the scene in groups one for the whole scene and one
for the pointer i want to move:
osg::Group* root = new osg::Group; // groupp have all other objects
osg::Group* Mainroot = new osg::Group; // the whole scene
Mainroot->addChild(root);
osgViewer::Viewer viewer;
osgViewer::Viewer viewer1;
//set left camera for left view
osg::ref_ptr cameraL = new osg::Camera;
...
// add the matrix transformation
osg::MatrixTransform* mt = new osg::MatrixTransform;
mt->setMatrix( cameraL->getViewMatrix() );
mt->addChild( loadedMode35 );
Mainroot->addChild(mt);
viewer.setCameraManipulator( keyswitchManipulatorL.get() );
//set right camera for the right view
osg::ref_ptr cameraR = new osg::Camera;
viewer1.setCameraManipulator( keyswitchManipulatorR.get() );
//load data for each viewer
viewer.setSceneData( root);
viewer1.setSceneData( Mainroot);
//run the viewer
while( !viewer.done() )
{
// fire off the cull and draw traversals of the scene.
viewer.frame();
viewer1.frame();
}
now the object i used did not move what is the problem ??

Re: [osg-users] current View Point
sorry for much truble but i looked and found two ways can not understand how
they work
the first way is to use call back :
so i added to the code :
class UpdateCallback : public osg::NodeCallback
{
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
std::cout<<"update callback - pre traverse"<setUpdateCallback(new UpdateCallback());
but it made no changes.
the second way :
i added to the code :
// Given a Camera, create a wireframe representation of its
// view frustum. Create a default representation if camera==NULL.
osg::Node*
makeFrustumFromCamera( osg::Camera* camera )
{
osg::Node* loadedMode35 ;
loadedMode35 = osgDB::readNodeFile("red.3DS");
// Projection and ModelView matrices
osg::Matrixd proj;
osg::Matrixd mv;
if (camera)
{
proj = camera->getProjectionMatrix();
mv = camera->getViewMatrix();
}
else
{
// Create some kind of reasonable default Projection matrix.
proj.makePerspective( 30., 1., 1., 10. );
// leave mv as identity
}
// Get near and far from the Projection matrix.
const double near = proj(3,2) / (proj(2,2)-1.0);
const double far = proj(3,2) / (1.0+proj(2,2));
// Get the sides of the near plane.
const double nLeft = near * (proj(2,0)-1.0) / proj(0,0);
const double nRight = near * (1.0+proj(2,0)) / proj(0,0);
const double nTop = near * (1.0+proj(2,1)) / proj(1,1);
const double nBottom = near * (proj(2,1)-1.0) / proj(1,1);
// Get the sides of the far plane.
const double fLeft = far * (proj(2,0)-1.0) / proj(0,0);
const double fRight = far * (1.0+proj(2,0)) / proj(0,0);
const double fTop = far * (1.0+proj(2,1)) / proj(1,1);
const double fBottom = far * (proj(2,1)-1.0) / proj(1,1);
// Create parent MatrixTransform to transform the view volume by
// the inverse ModelView matrix.
osg::MatrixTransform* mt = new osg::MatrixTransform;
mt->setMatrix( osg::Matrixd::inverse( mv ) );
mt->addChild( loadedMode35 );
return mt;
}
and i was suppose to change the loop to :
while (!viewer.done())
{
// Update the wireframe frustum
root->removeChild( 0, 1 );
root->insertChild( 0, makeFrustumFromCamera(
viewer.getView( 0 )->getCamera() ) );
viewer.frame();
}
but i was not sure what is this suppose to do ??
also i did not find "viewer.getView" function or equivelant to it
is there some way to help me fix or understand one of the two previous ways or
is there a way to directly update the node positon from the camira position in
the loop like using :
osg::NodeCallback* nc = new osg::AnimationPathCallback(
),osg::Vec3(0.0f,0.0f,1.0f),osg::inDegrees());
transform->setUpdateCallback(nc);
or transform(x,y,z)
rotate (h,p,r);
and get it directly from the current camera position matrix ?
please help

Re: [osg-users] my current position
thanks again for your help :
but i have another problem :
while( !viewer.done() || !viewer1.done() )
{
viewer.getCamera()->getViewMatrixAsLookAt(eye, center, up);
cout << "eye2 " << eye.x() << " " << eye.y() << " " << eye.z()
<< endl;
cout << "center " << center.x() << " " << center.y() << " " <<
center.z() << endl;
cout << "up " << up.x() << " " << up.y() << " " << up.z() <<
endl;
osg::Matrixd m(viewer.getCamera()->getViewMatrix());
mt->setMatrix(osg::Matrix::translate(eye.x(),eye.y(),eye.z())*
osg::Matrix::rotate(m.getRotate().inverse()));
i tried m.getRotate().inverse() and m.getRotate()
they rotate the object but i the wrong way they flip it
does any one have recomendations ??

[osg-users] synchronize two view windows
hello :
i need to synchronize two view windows .
i created two views and one key switch Manipulator
i want as i walk in one window my view synchronized in the other window with
solaly differ view.
this is my try but it is drive in the first view but no moves happened in the
second view :
while( !viewer.done() || !viewer1.done() )
{
viewer.getCamera()->getViewMatrixAsLookAt(eye, center, up);
viewer1.getCamera()->setViewMatrixAsLookAt(eye, center, up);
viewer.frame();
viewer1.frame();
}
what iam doing wrong ?

By default the OSG will use anaglyphic stereo when you enable stereo, but it also supports a range of other stereo options. For shutter glasses you'll probably just need to request quad buffer stereo via: osgviewer cow.osg --stereo QUAD_BUFFER For more command line details run osgviewer --help And via env vars: osgviewer --help-env Programatically you can enable stereo via osg::DisplaySettings (the above command line options and env vars just set it.) See the osgstreoimage example for an example of programmatically enabling stereo. There is a big but... and that's does you graphics card/OpenGL driver support quad buffer stereo. I can't answer this as you've provide no info w.r.t hardware/drivers you are using. For NVidia it's just their Quadro line that supports quad buffer stereo.

This is pretty poor considering that you've got the NVidia 3D glasses. Perhaps the NVidia drivers only provide a hack for 3d support in 3rd party apps, as they do for games. I would be worth contacting NVidia about it as frankly selling hardware but not supporting quad buffer stereo in the drivers is just plain incompetent/fraudulent. Robert.

i used exactly the line : osgviewerd cow.osg --stereo QUAD_BUFFER but it give me the previous worning and when the window opend the shutter did not sence it at all should i change the shutter or what ? --- On Tue, 5/12/09, Robert Osfield wrote: From: Robert Osfield Subject: Re: [osg-users] Stereo Problem To: olfat_ibra...@yahoo.com, "OpenSceneGraph Users" Date: Tuesday, May 12, 2009, 9:23 AM HI Olfat, On Tue, May 12, 2009 at 1:49 PM, olfat ibrahim wrote: > > Hello > > i got into Nvidia website and downloaded the last driver version for my > glasses. the glassess still not filling my application but it is now give > only the following error. > > Warning: Could not find plugin to read objects from file > "QUAD_BUFFER". > > u saing that it is not working with openGL so any one have any > recommendations for me. Exactly what command line are you using now? It sounds like you might have an error on the command line. Please have a look back over my earlier email.

I've tried to reproduce this error at my end with lots of different combinations but can't, the command line parser always works correctly. Others do use quad buffer stereo with the OSG successfully, but probably only with drivers that officially support it. As a sanity test, does osgviewer cow.osg work fine? Also try setting the stereo mode via the env var: set OSG_STEREO_MODE=QUAD_BUFFER osgviewer cow.osg --stereo Beyond the above there isn't anything I do to help any further. I don't have the hardware or OS to test against. If the above doesn't work go complain to Nvidia.
