Implementation of the Progressive Meshes for Distributed Virtual Museum

This article presents a specific part of the idea of distributed virtual museum. The intention of the authors is to fulfill one of the scenarios for Future Internet and to give a set of requirements for future properties of the global network. A progressive mesh is a lossless approximation of the original mesh model at any, smoothly adjusted, level of detail. The main part of this work is devoted to the extension of progressive meshes for hierarchical representation associated the position of observation. This allows the selective adjustment of the level of detail, measured in the number of triangles that appear in any fragment of the model, independently from the rest. Sample solution was presented, as well as the method of construction and the main criteria for the refinement.
