: In this paper, the suitability and usability of VRML for urban modelling is discussed based on the experience gained by the creation of urban models of varying sizes, level of detail and use. Areas where the current VRML specification is failing to satisfy the needs of large-scale urban modelling are highlighted. Properties of a successful alternative or VRML3.0 specification are suggested and briefly discussed. Keywords: VRML, virtual word design, digital urban models. 1. Background During the past six years a series of three-dimensional urban computer models have been developed in the Centre for Advanced Studies in Architecture (CASA) at the University of Bath. Computer models were constructed in order to assist in making the planning and development control process more flexible by providing a means by which planning proposals could be visualised and alternative schemes for a site compared; allowing nonexperts to comprehend the implications of proposed changes. Developments in the...
