整理3D中的数据点
我有一组应该定义光滑表面的数据点。 X / Z以间隔指定，Y取决于Y / Z。
将点的位置四舍五入到固定公差范围内。
如果通过X或Z切片绘制一条曲线（例如样条曲线），则四舍五入会使曲线呈锯齿形或创建台阶。
例如，一组形成直线的线性值，当四舍五入为整数时，形成一个台阶：
1 1 2 2 3 instead of 1 1.5 2 2.5 3
要做的是公平地处理数据，将舍入后的值转换为能产生平滑曲线的实值，该平滑曲线将定义平滑表面而不会产生振荡。
有一些工具可以在2D上执行此操作。他们寻找2d导数的振荡。在我的案例中，这产生的问题是，沿X / Y曲线的光顺可能沿相交的Y / X曲线的光顺。我需要创建一些可以同时沿X / Y和Y / Z对齐的东西。
我想知道是否有人知道这样做的算法。
