Abstract:
Autonomous cars already exist, why should anybody these days spend manual time on mesh preparation? This is a task for the machine and no the human being. In this session, we will show the one-click way to prepare the mesh for multi bodies or topological complex objects for 3D printing. The underlying software is already in use for paint shop applications to prepare a body in white starting from CAD fully automatic with 5-8 hours computational time of a desktop machine, while the labour work is kept less than 15 minutes. For input, tessellated data can be imported from several sources (there are automatic interfaces to extract the data of multi bodies from CAD). Often these data is defective and not manifold. In addition, the describing surface is not represented in an exact way. The only exact information one can rely at this stage is the position of the vertices of the mesh. They are located directly on the surface. The edges and areas of the triangles may have a deviation of the original surface. The overall goal is to rely on vertices and if needed dismiss the rest of enhance the rest. The underlying software uses several techniques to repair, connect and maintain the surface geometry by not only keeping the boundary representations exact - the software even enhances the quality. In this presentation we will reveal techniques, how it is possible to obtain the above described functionalities.
