适用范围：This part of ISO/IEC 14496 describes a model for connecting 3D graphics compression tools defined inISO/IEC 14496 to graphics primitives defined in any other standard, specification or recommendation.The goal of this part of ISO/IEC 14496 is to specify an architectural model able to accommodate• third-party XML based descriptions of scene graph and graphics primitives with• (potential) binarization tools and with• MPEG-4 3D graphics compression tools specified in ISO/IEC 14496-2, ISO/IEC 14496-11 andISO/IEC 14496-16.The advantages of such an approach are on the one side the use of powerful compression tools for graphicsand on the other side the generality of graphics primitives representation. Hence, compression toolsdeveloped in ISO/IEC 14496-2, ISO/IEC 14496-11 and ISO/IEC 14496-16 would be applied not only to thescene graph defined by ISO/IEC 14496-11 but to any scene graph definition. The bitstreams obtained whenusing the model are MP4 formatted and contain XML (or binarized XML) for the scene graph and binaryelementary streams for graphics compression (geometry, texture and animation).
