Abstract:
A method for determining a z-buffer granularity in a scene represented by a binary tree having leaf objects, the method comprising the steps of:(a) determining a non-normalized risk parameter; (b) computing a primary hit value mean for a first object; (c) computing a secondary hit value mean for a second object; (d) computing a primary hit value variance for the first object; (e) computing a secondary hit value variance for the second object; (f) determining an optimal fraction of available graphics resources to be allocated to the first 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 (i) computing a z-buffer average depth based upon allocated graphics resources for each leaf object and a distance of each object from an observation point.
