[osg-users] how to disable the frustum culling?

[Julio Jerez]

I am get a lot of frustration trying to disable frustum culling with OSG
camera.

I am setting the perspective matrix to  a near plane of 0.1 and a far plane
of 1000.0

here is my code.

I explicitly disable frustum culling, however no matter how many time I do
it,  each time 

viewer.frame() is called, the camera rest the near plane to 0.112 and the
far plane to 228.56

 

can someone tells me how to prevent OSG from doing that?

here is my setup code that initialize the camera after the viewer is
instantiated.  

 

               SetCameraProjectionMatrix (viewer, 90.0f, dFloat (width) /
height, 0.1, 1000.0f);

 

               int cullingMode = cam->getCullingMode();

               cullingMode &= ~osg::CullSettings::VIEW_FRUSTUM_CULLING;

               cam->setCullingMode(cullingMode);

}

 

void SetCameraProjectionMatrix (osgViewer::Viewer& viewer, dFloat
viewAngleInDegress, dFloat aspectRatio, dFloat nearPlane, dFloat farPlane)

{

               osg::Camera* const camera = viewer.getCamera();

               camera->setProjectionMatrixAsPerspective (viewAngleInDegress,
aspectRatio, nearPlane, farPlane);

 

//            camera->setViewMatrixAsLookAt (osg::Vec3 (3.0f, -5.0f, 2.0f),
osg::Vec3 (0.0f, 0.0f, 0.0f), osg::Vec3 (0.0f, 0.0f, 1.0f));

               camera->setViewMatrixAsLookAt (osg::Vec3 (-3.0f, -5.0f,
2.0f), osg::Vec3 (0.0f, 0.0f, 2.0f), osg::Vec3 (0.0f, 0.0f, 1.0f));

}
