Until recently, a major drawback of declarative-3D approaches for the Web was the encoding of scene-graph-related structured data along with a text-based description of unstructured vertex data. Loading times were long, and 3D Web content wasn't available until the full page had completely loaded. To overcome this limitation requires external mesh data containers that are referenced in the scene description. In particular, sequential image geometry containers and explicit binary containers align well with GPU buffer structures, thus enabling fast decoding and GPU uploads. Furthermore, progressive binary geometry enables simple, yet highly progressive transmission of arbitrary mesh data on the Web.
