object identification in compressed view-dependent multiresolution meshes
We present a method that allows to identify individual objects in a view-dependent multiresolution triangle mesh. Unlike previous methods, where the input mesh was considered a uniform "triangle soup", our method enables passing of object semantics through the process of encoding, transmission, and decoding. This information can be used on the client side to query additional data to a specific part of the mesh. Moreover, it allows a part of the mesh to be transformed (e. g., moved to a different location for better inspection) within the multiresolution framework of adaptive refinement. Finally we show that the overhead introduced by our method is negligible.The algorithm has been tested with artifically and manually created data and with models acquired within the digital archaeology project "3D MURALE".
