This node defines an application region and an associated aural attribute component object that controls reverberation and atmospheric properties that affect sound source rendering. Multiple Soundscape nodes can be included in a single scene graph. <P> The Soundscape application region, different from a Sound node's scheduling region, is used to select which Soundscape (and thus which aural attribute object) is to be applied to the sounds being rendered. This selection is based on the position of the ViewPlatform (i.e., the listener), not the position of the sound. <P> It will be common that multiple Soundscape regions are contained within a scene graph. For example, two Soundscape regions within a single space the listener can move about: a region with a large open area on the right, and a smaller more constricted, less reverberant area on the left. The rever- beration attributes for these two regions could be set to approximate their physical differences so that active sounds are rendered differently depending on which region the listener is in.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0"
