1. A method for displaying a leaf object and an other object in a scene, the method comprising the steps of:

  • determining a non-normalized risk parameter;

    computing a primary hit value mean for the leaf object;

    computing a secondary hit value mean for the other object;

    computing a primary hit value variance for the first leaf object;

    computing a secondary hit value variance for the other object;

    determining an optimal fraction of available graphics resources to be allocated to the leaf object based upon the non-normalized risk parameter, the primary hit value mean, the secondary hit value mean, the primary hit value variance, and the secondary hit value variance; and

    selecting a level of detail for the leaf object based upon the optimal fraction and the available graphics resources.
