[osg-users] odd scene resize

[Robert Osfield]

Hi Gianni,

The osgViewer automatically adjusts the field of view on the camera
according to the aspect ratio adjustment setting, you can change this,
from the osg::Camera header:

       enum ProjectionResizePolicy
        {
            FIXED, /**< Keep the projection matrix fixed, despite
window resizes.*/
            HORIZONTAL, /**< Adjust the HORIZONTAL field of view on
window resizes.*/
            VERTICAL /**< Adjust the VERTICAL field of view on window resizes.*/

        };

        /** Set the policy used to determine if and how the projection
matrix should be adjusted on window resizes. */
        inline void setProjectionResizePolicy(ProjectionResizePolicy
policy) { _projectionResizePolicy = policy; }

        /** Get the policy used to determine if and how the projection
matrix should be adjusted on window resizes. */
        inline ProjectionResizePolicy getProjectionResizePolicy()
const { return _projectionResizePolicy; }
