Hello,

when i create a camera:

osg::ref_ptr< osg::Camera> cam = new osg::Camera();

and I want to get the frustum parameters:

cam->getProjectionMatrixAsFrustum(left,right,bottom,top,znear,zfar);

I dont't get the parameters. It seems that the camera hasn't a projection matrix. Where is the projection matrix define in this situation? When I set my own projection matrix with setProjectionMatrix( ... ) it works fine.

Cheers,

Martin
