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

Hi Roman,
During traversal the cull traversal mask is AND'd with the node mask
and if it returns a non zero value then the node and its subgraph are
traversed, so as you've set it 0x2 & 0x2 will pass. Set the traversal
mask to ~0x2 and you should get the result you want.

Hi guys!
Node masking don't work at all for me
I setup node like this:
osg::Group* heli=(osg::Group*) osgDB::readNodeFile("ah64d.flt");
heli->setDataVariance(osg::Object::DYNAMIC);
heli->setNodeMask(0x2);
osg::PositionAttitudeTransform* patTarget = new
osg::PositionAttitudeTransform();
patTarget->addChild(heli);
targetDataType* targetData = new targetDataType(patTarget);
patTarget->setUserData( targetData );
root->addChild(patTarget);
patTarget->setUpdateCallback(new updateTargetCB(tIDevState));
and viewer like this:
int inheritanceMask =
(osg::CullSettings::VariablesMask::ALL_VARIABLES &
~osg::CullSettings::VariablesMask::CULL_MASK);
viewer.getCamera()->setInheritanceMask(inheritanceMask);
viewer.getCamera()->setCullMask(0x2);
but I still see my node. How can I disable this node?
Could you please tell me what I'm doing wrong?
Thanx in advance
Bye
