基于特征保持的三角形折叠网格简化算法
Mesh Simplification Algorithm of Triangle Collapse Based on Feature Preserving
摘要
Abstract
When the 3D models are simplified by existing algorithm,the features of the simplification models can not be preserved very well and the generated triangles are distributed evenly. Based on feature preserving ,present an improved triangular mesh simplification algorithm based on triangle collapse. Classify triangles of the original model before the simplification. The simplification process is measured with quadric error metrics and under the control of three factors: the long and narrow degree of triangle, the local region area and the local region sharpness. Different triangle uses different simplified strategy. The algorithm is implemented with OpenGL programming language in the developing environment of Visual C++ 6.0. Experimental results demonstrate that the algorithm runs fast and can keep the features of the original model effectively by delaying the simplification of the featured regions and the well-shape triangles.关键词
