摘要
结合三角形和四边形混合网格的特点,提出了一种混合网格上数据后处理的方法。该方法通过顺序地寻找单元边上的数据插值点从而形成多边形,然后赋予不同颜色来映射不同数据值。该方法对三角形和四边形采用相同的计算方法,从而适合混合网格上的数据显示。以OpenGL图形库为开发工具对方法进行了验证,并给出实验结果。该方法也可应用于三维网格的数据后处理。
Considering the characteristics of the triangular-quadrilateral mixed-mesh, one data post-processing method was proposed for the mixed-mesh. In this method, the polygon was created to represent the given range of data value by sequentially finding the interpolation points on the edges, the various colors are assigned to the polygon as showing the different data range. The proposed method can deal with the triangular element and quadrilateral element by the same procedure. Based the OpenGL, the visualization method was demonstrated and the results were illustrated. This method was suitable to be applied to 3D mixed-meshes.
