||One of the most interesting areas in the forefront of non-immersive virtual reality (VRML) applications to architecture is the one that concerns the design, construction and exploration of on-line multi-access worlds using the Internet-WWW. However, and despite the great proliferation of earlier single-access models built on VRML, attempts to collect, classify and provide accesibility that type of models has proved almost nil. On the other side, one of the architectural typologies that promises the greatest transformation potential in the virtual architecture area in cyberspace is the one that concerns virtual museums and galleries. This paper seeks to provide a bridge between the two aforementioned approaches by formulating a conceptual basis for the creation of a virtual, on-line, multi-access museum intended to house collections of VRML building models. Such models, initially shown at a conventional model scale, would be accessed by visitors through an interface intended to transport those visitors into the models’ environments, where changes in scale could provide navigation access to interior and exterior view of the building . Accordingly, the museum would act as a sort of "spaceport” toward different routes of exploration. This modelistic cascading seems to offer interesting possibilities as regards future virtual architecture applications.
