Abstract : We propose an original hybrid modeling process that represents threedimensional (3D) models as a combination of meshes and 3D-primitives. Meshes describe details such as ornaments or statues, whereas 3D-objects code for regular shapes such as walls or columns. Starting from a mesh obtained by multi-view stereo techniques, these primitives are substituted to the mesh where they are detected. This strategy allows the introduction of semantic knowledge, the simplification of the modeling, and even corrections of errors generated by the acquisition process.
