给出了数据分块系统性方案，即从仅含有三维坐标的散乱的点云中自动提取几何曲面特性。
A systematic scheme is proposed to automatically extract geometric surface features from a point cloud composed of a set of unorganized three-dimensional coordinate points by data segmentation.
通过调整这两个系杆结束，转向节杆结束，确保有一个中立的转向几何曲面，和甚至脚趾端。
By adjusting both tie rod-ends and steering knuckle rod-ends, insure steering geometry has a neutral camber, and even toe-end.
就是做F·dS或是F·ndS的二重积分，为了能建立积分，需要用到曲面的几何性质，这与该曲面的类型有关。
Double integral of F.dS or F.ndS if you want, and to set this up, of course, I need to use the geometry of the surface depending on what the surface is.
