画3D图重构，由二维切片画三维图，讲述和实现画3D图重构，由二维切片画三维图-画3D图重构

画等高线（带色彩蒙板），只要你由点的三维坐标，就可以利用这个程序帮你画出立体的模拟图-Draw contour lines (with color mask), as long as you point by the three-dimensional coordinates, you can use this program to help you draw three-dimensional simulation of Fig.

如何读取数据textread，例如通过textread( x_inlet.txt )我们可以把文件x_inlet.txt中的数据存储到数组x中，且x的维数和大小会自动与文件x_inlet.txt的相匹配。 如何画三维曲面图surf，例如 surf(x,y,z)，其中xy分别为n,m个元素的一维数组时，z必须为n*m的二维数组。-How to read the data textread, for example, through x textread ( x_inlet.txt ) we
