Hi Robert
You are definitly right!
When I set camera's matrix in main frame loop all works fine.
But is there a way to use callbacks in my situation?
Maybe osgViewer::SimpleViewer attach camera to root node and
osgViewer::Viewer don't?

I don't know what's up, perhaps the nod masks you are using are
affecting the update traversal. It could be that the Camera's update
callback isn't being called because its part of the viewer rather than
the scene graph.
You try just setting the Camera's view matrix in the main frame loop
rather than as an update callback.

Thanx Robert!
All works now but I found that I used SimpleViewer instead Viewer
so cullmask works perfectly but Now my camera callback don't want to work
(I've got camera with trackball manipulator but I don't setup trackball
manipulator to my view.
so I use this to setup callback
viewer.getCamera()->setUpdateCallback(new RotateCB);
and here my callback
class RotateCB : public osg::NodeCallback
{
public :
RotateCB() : _angle(0.){}
virtual void operator () ( osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* camera= dynamic_cast<osg::Camera *>(node);
float azAngle(1.56f),elAngle(4.74f),twAngle(-1.57f);
camera->setCullMask(~0x01);
azAngle = ( az * PI ) / 180;
elAngle = ( el * PI ) / 180;
std::cout<<"rotateCB"<<std::endl;
osg::Matrixd myCameraMatrix;
osg::Matrixd cameraRotation;
osg::Matrixd cameraTrans;
cameraRotation.makeRotate(
osg::DegreesToRadians(0.0), osg::Vec3(0,1,0), // roll
osg::DegreesToRadians(el), osg::Vec3(1,0,0) , // pitch
osg::DegreesToRadians( az), osg::Vec3(0,0,1) ); // heading
cameraTrans.makeTranslate( 1,5,1 );
myCameraMatrix = cameraRotation * cameraTrans;
osg::Matrixd i = myCameraMatrix.inverse(myCameraMatrix);
camera->setViewMatrix(i*osg::Matrix::rotate(-(osg::PI_2),1,0,0));
traverse(node,nv);
}
protected:
double _angle;
};
Could you please tell me what I'm doing wrong?
Thanx in advance
Roman
