用Balder根据两个三维点创建Cylinder

本文主要是介绍用Balder根据两个三维点创建Cylinder，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Balder中自动创建的Cylinder默认是处于垂直状态的，如果想要根据两个三维坐标创建一个圆柱，那么就需要对刚创建的Cylinder进行旋转操作。

private Cylinder CreatePipeCylinderFromGraphic(double x1,double y1,double z1,double x2,double y2,double z2,double Radius,Color color){Cylinder cylinder = new Cylinder();                     double x0 = (x1 + x2) / 2;double y0 = (y1 + y2) / 2;double z0 = (z1 + z2) / 2;double length = Math.Sqrt((x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2) + (z1 - z2) * (z1 - z2));cylinder.Size = length;double VirtualX = x1 - x0;double VirtualY = y1 - y0;double VirtualZ = z1 - z0;double A = VirtualX / (length / 2);double B = VirtualY / (length / 2);double C = VirtualZ / (length / 2);double AngleX = Math.Asin(C) * 180 / Math.PI;double AngleZ = Math.Atan(-A / B) * 180 / Math.PI;if (y1 < y2) AngleZ += 180;cylinder.Rotation = new Coordinate(AngleX, 0, AngleZ);cylinder.Position = new Coordinate(x0, y0, z0);cylinder.TopRadius = cylinder.BottomRadius = Radius;            cylinder.Color = color;cylinder.Segments = 20; //圆滑程度return cylinder;}
