We consider the problem of transmitting huge triangle meshes in the context of a Web-like client-server architecture. Approximations of the original mesh are transmitted by applying selective reenement. A multiresolution geometric model is maintained by the server. A client may query the server for a mesh at an arbitrary, continuously variable, level of(More)
This paper describes preliminary research work aimed at obtaining a multi-level iconic representation of 3D objects from geometric meshes. A single-level iconic model describes an object through parts of different dimensions connected to form a hypergraph. The multi-level iconic model, called Non-manifold Multi-Tessellation, incorporates decompositions of(More)
In our previous work [2], we have shown that a non-manifold, mixed-dimensional object described by simplicial complexes can be decomposed in a unique way into regular components, all belonging to a well-understood class. Based on such decomposition, we define here a two-level topological data structure for representing non-manifold objects in any dimension:(More)
Abstract simplicial complexes are used in many application contexts to represent multi-dimensional, possibly non-manifold and nonuniformly dimensional, geometric objects. In this paper we introduce a new general yet compact data structure for representing simplicial complexes, which is based on a decomposition approach that we have presented in our previous(More)
In this paper we address the problem of building valid representations for non-manifold d-dimensional objects. To this aim, we have developed a combinatorial approach based on decomposing a non-manifold d-dimensional object into an assembly of more regular components, that we call initial quasi-manifolds. We present a decomposition algorithm, whose(More)
