Towards declarative 3D in web architecture

The recent WebGL integration in major web browser has open the way to many 3D applications as well as high-level libraries targeting 3D content developers. While most of these libraries provide solid grounds for interoperable 3D on web browsers, one might wonder if their use could not be simplified both in terms of processing overhead and 3D description syntax; looking beyond these issues, if there is room for a declarative 3D language for web architecture, its features should be well defined to ensure its success. In this paper, we review some use cases, some existing technologies and some drawback of existing tools in order to derive some requirement for the upcoming declarative 3D language for the HTML ecosystem.
