The editor shown in Figure 7 allows one to edit and monitor sound nodes [Bell et al. 96] in a virtual reality runtime environment. The user invokes the editor via mouse click on a sound node in the spatialization resource visualizer.
A source radiation pattern is defined by a core range and audible range, represented by the sound node fields minBack, minFront, maxBack, and maxFront. The resource allocation algorithm uses the priority value to rank the sources. The fields direction and location change orientation and position of the sound node in its local coordinate space. Changes are immediately manifested in the spatialization resource visualizer. If the field values are modified during runtime by the application, the fields in the attached editor are updated. This allows textual sound behavior monitoring of a scene.
