Algorismes paral·lels SIMD d'extracció de models de fronteres a partir d'arbres octals no exactes
A new SIMD parallel algorithm to extract a Boundary representation from Classical Octrees is presented. The algorithm makes use of a Geometrically Deformed Model (GDM) to smooth an initial naive polygonization. The GDM used is profited as well to compute a Face Octree from the raw data. The smoothed...

| Sumario: | A new SIMD parallel algorithm to extract a Boundary representation from Classical Octrees is presented. The algorithm makes use of a Geometrically Deformed Model (GDM) to smooth an initial naive polygonization. The GDM used is profited as well to compute a Face Octree from the raw data. The smoothed verbose polygonization and the Face Octree are combined to obtain a more concise boundary representation within tolerance requirements. |
