在综合多种算法优点的基础上，首先提出了对三角面片的顶点按其切片方向进行从小到大排序，以快速滤除冗余顶点；
Firstly, sorting the apex of the triangular facets according to ascending order in their slice direction was proposed to filter out redundant vertex quickly;
你可以创建在高度方向的图像切片，让它像对脑部扫描的医疗图片一样，一幅一幅连起来运行变成成电影。
You can create an image slice-by-slice in height, and run it as a movie just like a medical image through a brain scan.
首先求出能够表示模型垂直方向轮廓变化情况的参考曲线，然后在切片时根据参考曲线上各点处切线确定在该处的切片厚度。
The algorithm firstly determines reference curves that can express vertical outline change of the model, and then select slicing thickness according to tangent of poi.
