This paper treats a 3D graphics software development system called IntelligentBox known as a 3D meme media system and its web version (WebIB). IntelligentBox provides various 3D software components called boxes each of which has a unique functionality and a 3D visible shape. IntelligentBox also provides a dynamic data linkage mechanism that allows users to develop interactive 3D graphics applications only by combining already existing boxes through direct manipulations on a computer screen. Recently, the author extended IntelligentBox system to make it possible to develop interactive web 3D contents. This is called the web version of IntelligentBox (WebIB). This extended mechanism is also regarded to be available for the integration of IntelligentBox with Webble World, an open web-based meme media environment. This paper explains essential mechanisms of IntelligentBox and WebIB, introduces some interactive web 3D contents realized using WebIB, and also discusses about the possibility of the integration of IntelligentBox with Webble World.
