- W2372520622 abstract "In the field of computer visualization, three-dimensional object is usually rendered by triangle meshes,but too many triangle meshes can affect the result of real-time operation, such as shifting, rotation and zooming, most of users can't bear the slowness. So how to simplify the triangle meshes is regarded more and more important. To simplify triangles effectively while not influence the vision effect, based on the traditional method of edge contraction, a new method is presented, which named Two Times of Local Mapping. First, it maps the three-dimensional triangle meshes from three-dimensional space to two-dimensional plane by using Gaussian sphere which can determine the direction of projection. Then on two-dimensional plane, using the traditional edge contraction method, a new contracted point is found in the kernel of a polygon. With the new point, the number of triangles is reduced greatly. After simplification, when mapping the simplified triangles back to three-dimensional space, the error is checked. Two kinds of error are defined to ensure the minimum error. It is proved that the given method is little-error, efficient and without self-intersected, and also it is stable and applicable." @default.
