ABSTRACT:
A method for determining a depth ordering between two planes in a 3D workspace of an application is provided. The method includes projecting vectors from a reference position through points of interest on the planes, determining corresponding points on the other plane, determining a number of points of interest on a first plane having a depth lower than its corresponding point and a number of points of interest on a second plane having a depth lower than its corresponding point, and setting the depth ordering based on these numbers. A method for displaying interconnects between nodes of a tree displayed in an application is provided. A node represents a multimedia item or a function and an interconnect represents data passed between two nodes. The method includes displaying an interconnect in the tree having an appearance indicating at least one characteristic of the data being passed between two nodes.
