| Description | Reconstruction of a simplified mesh Local dynamic reconstruction refinement Figure 1. Our reconstruction framework, illustrated on the TRIPLE HECATE model. Starting from a dense input point set, we reconstruct a simplified mesh (center). Benefiting from the connectivity of this initial reconstruction, we can make it to evolve dynamically so as to refine the approximation locally. This refinement can be achieved either in an automatic fashion, for example in order to improve the quality of the elements of the mesh, or interactively, in order to add or remove sample points. Here, the draped dress has been locally enhanced (right). In this paper, we introduce a flexible framework for the reconstruction of a surface from an unorganized point set, extending the geometric convection approach introduced by Chaine [9]. Given a dense input point cloud, we first extract a triangulated surface that interpolates a subset of the initial data. We compute this surface in an output sensitive manner by decimating the input point set on-the-fly during the reconstruction process. Our simplification procedure relies on a simple criterion that locally detects and reduces oversampling. If needed, we then operate in a dynamic fashion for local refinement or further simplification of the reconstructed surface. Our method allows to locally update the reconstructed surface by inserting or removing sample points without restarting the convection process from scratch. This iterative correction process can be controlled interactively by the user or automatized given some specific local sampling constraints. |
