Abstract	This paper proposes a novel, yet extremely compact model representation method. Its main feature is that 3D shapes are represented in terms of functions instead of geometric primitives. Given a set of – typically only a few – specific parameters, the evaluation of such a function results in a model that is one instance of a general shape. Particularly important for the web context with client systems of widely varying rendering performance is the support of a semantic level-of-detail superior to any low-level polygon reduction scheme. The shape description language has the power of a full programming language, but it has an extremely simple syntax. It can be regarded as some form of a ’mesh creation/manipulation language’. It is designed to facilitate the composition of more complex modeling operations out of simpler ones. Thus, it allows to create highlevel operators which evaluate to arbitrarily complex, parameterized shapes. The underlying shape representation is a boundary representation mesh in combination with Catmull/Clark subdivision surfaces.
