Mesh Simplification for Virtual Objects Disassembly (j-FIG 2018, Poitiers, France)

Résumé

Progressive mesh simplification by successive edge collapses is a standard tool in geometry processing with most previous works focusing on local shape preservation. However, CAD models describing complex systems often require significant decimation for visualization on low end terminals, and preserving the objects arrangement is crucial to maintain the system readability and thus enable virtual disassembly for training purposes for instance. In this work, we focus on preserving proximity relations between meshes during the decimation process. We present a novel approach for the joint decimation of multiple meshes by combining a local edge error using Quadric Error Metric with a proximity-aware penalty function to increase the error of edges close to other meshes and thus delay their collapse. We also propose a generic method to define proximity for a scene and demonstrate the performances of our approach on several CAD scenes.
