【C#】基于OpenGL的STL模型机加工路径生成器
程序主界面
实验视频
该软件基于C#开发，用到了Tao.OpenGL库，OpenTk库。 可以加载STL格式的模型，在OpenGL场景中显示模型，平移和旋转模型。通过聚类算法对模型的三角网格进行分组和简化，通过选择网格组生成路径点，也可以通过选择边上的点创建路径点。生成的路径点可以通过调整旋转角度，来调节机加工刀具的方向，路径起始位置增加进刀路径和结束位置增加退刀路径。 生成的路径可转化并导出为设备指令用于机器人或者机床进行机加工或者焊接等操作。

break;
}
if (hit == false)
return;
//-----------设置组合颜色 set group and color
if (SelectedGroup.Where(p => p.ID == ID).Count() == 2) { // 选择了两个网格面
// 双选时更改组和颜色 change group and color when double select
SelectedGroup.RemoveAt(SelectedGroup.Count() - 1); //移除重复的项 remove repeat item
//切换分组：组A 组B 切换

}
else {

}
MakeSortedList();//更新 创建已分组列表。
}
else {//第一次选择网格，设置分组A
// set group and color on selected item

MakeSortedList();
}
//-----------groupS 和 group B 之间的相交边 intersect edge betewwn groupA and groupB
myLines.Clear();//网格相交线条集合清空
var points = new HashSet(); //交点集合
foreach (var gA in SelectedGroup.Where(p => p.groupA == true))//遍历组A中网格gA

if (intersect.Count() == 2) {//a b 两个三角网格有两个交点
myLines.Add(new MyLine(intersect[0], intersect[1]) { Norm = b.norm });//交线添加到线条集合
foreach (var c in intersect)//遍历交点

}
}
//-----------绘制边 draw edge

}
Gl.glBegin(Gl.GL_LINES);//绘制线条
Gl.glLineWidth(2);//线宽2
Gl.glColor3ub(255, 0, 0);//红色
foreach (var p in myLines) {//遍历所有相交线集合
//线条：相交线的起点 ----->起点沿法线方向移动15
Gl.glVertex3f(p.Start.X, p.Start.Y, p.Start.Z);
Gl.glVertex3f(p.Start.X + p.Norm.X * 15, p.Start.Y + p.Norm.Y * 15, p.Start.Z + p.Norm.Z * 15);

} 八、保存机器人路径序列化文件并压缩
public class TMpath {
private List robotPath;//机器人路径 位姿列表

//构造函数
public TMpath (List RobotPath) {

}
//选择和创建： 目录名，速度

fbd.ShowDialog();
var path = fbd.SelectedPath;//获取选择的目录
if (path != null) {
path = Path.Combine(path, FileName);//文件夹+目录名FileName
Directory.CreateDirectory(path);//创建目录
RootPath = path;//根目录
path += $@"\path1.PATH";//机器人路径 path1.PATH
CreatePathFile(path, speed);//创建路径文件
RunZip(RootPath);//压缩根目录
}
}
//创建配置文件
private void CreateConfig (string path) {
using (StreamWriter sw = new StreamWriter(path + @"/ConfigData.XML")) {
sw.WriteLine(@" Point { get; set; } = new List();//路径点列表，包含速度
