Parameterization Method for Multi-scale Regular-grid Model Repairing Cracks

  

  • Received:2012-08-16 Revised:2013-05-05 Published:2013-06-20

Abstract: When using level-of-detail (LOD) technology, Multi-scale regular grid visualization always introduces discontinuous mesh on the boundary with different resolutions. Researching GPU-based LOD framework for cracks repairing, in this paper, we propose parameterization method to avoid cracks. We employ function curve fitting to change the mesh layout and eliminate T-junctions caused by various LODs transiting. Moreover, the parameterization cracks-repairing method supports multi-span LOD using curve function family excellently. Function curve fitting method is utilized to existing regular-grid-based LOD model. The experiments show that, our method improves cracks-repairing performance simultaneously while guaranteeing mesh continuity.

Key words: computer application, cracks repairing, function curve, level of detail, regular grid
