The first bezier spline is drawn from the first point to the fourth point in the pointarray.
第一个贝塞尔样条是从点数组中的第一个点到第四个点绘制成的。

The quadrilateral grid graph of closed surfaces was obtained through surface slicing, offset point picking up, ordering of pointarray, 1d interpolation, and data merging.
经过曲面切片、型值点提取、点列排序、一维插值、数据融合,得到闭曲面四边形网格图。

However, when it came to creating non standard shapes (in particular curved surfaces) I find myself using graph paper to sketch, and then manually putting a large number of point into a pointarray.
