四边形网格生成代码
我正在寻找一些四边形网格生成的示例代码(任何语言)。然而,这似乎是一项相当艰巨的任务!
我不挑剔,我想至少对有孔的多边形进行网格划分,没什么花哨的!所以,我们在这里讨论的是二维平面形状。
有什么提示吗?
附言。当然,如果它甚至可以处理曲面,我会更高兴!
I am looking for some sample code (any language) of quadrilateral mesh generation. However, is seems quite a difficult task!
I am not picky, I'd like to mesh at least polygons with holes, nothing fancy! So, we're talking about 2D planar shapes here.
Any hint?
PS. Of course, if it could even handle curved surfaces, I'd be even happier!

四边形网格划分绝非易事,尤其是当单元或多或少形状良好时。没有算法可以处理任何任意形状而不恶化元素形状。对于很多问题类别,应用数学和计算科学书籍和论文中都有算法。
Quadrilateral meshing is by no means easy, especially if the elements should be more or less well-formed. There are no algorithms that can deal with any arbitrary shape without deteriorating element shapes. For a whole lot of problem classes, there are algorithms in applied mathematics and computational science books and papers.
