I think this has something to do with "fustrum". I use this
code:
double fovy=45.;
double aspectRatio=1.32773;
double zNear=0.2;
double zFar=50000.;
osg::Matrixd CameraPerspective;
CameraPerspective.makePerspective( fovy, aspectRatio,
zNear, zFar);
viewer.getCamera() -> setProjectionMatrix(
CameraPerspective );
viewer.getCamera() -> setComputeNearFarMode(
osgUtil::CullVisitor::DO_NOT_COMPUTE_NEAR_FAR );
bye
