Skyline创建三维管线两种方式（C#）

先简单说一说skyline软件的系统，skyline软件主要有TerraBuilder，TerraExplorer以及TerraGate。TerraBuilder主要是采用图像，dem等生成地形，制作成三维地球或三维平面；TerraExplorer的功能是编辑和浏览（关键部分）；TerraGate主要是网络功能。换句话说，Terrabuilder是数据制作源，TerraExplorer是数据可视化窗口。想了解更多http://help.skylineglobe.cn/forum.php?mod=forumdisplay&fid=36

（一）二次开发准备

打开vs2010，在工具栏处右键，添加选项卡，建立skyline控件组，在建好的组内，右键选择项



添加skyline有关的com组件



添加完成后，将会得到如下控件：



TE3DWindow是三维浏览窗口，TEInformationWindow是树信息目录窗口，TENavigationMap是鹰眼窗口。

（二）管线生成

//接口的使用

TECoClass = new TerraExplorerClass();

mTerraExplorer = (ITerraExplorer5)TECoClass;

mPlane = (IPlane5)TECoClass;

mNavigation = (ITENavigationMap5)TECoClass;

mRender = (IRender5)TECoClass;

mMenue = (IMenu)TECoClass;

mObjectManager = (IObjectManager5)TECoClass;

mInformationTee = (IInformationTree5)TECoClass;

//加载三维球

mTerraExplorer.LoadEx(@"C:\globe.fly", "", "", 0);//或者mpt文件，可以使用Terrabuilder生成。

管线绘制的代码生成主要有两种方式：

1.单管段

int iGround = mInformationTee.CreateGroup("管线",
0);

double x1 = 0, y1 = 0, z1 = 0, x2, y2, z2;

double pipeLength;

double fillOpacity = 0.7;

double pipeRadius = 2;

object oYaw, oPitch;

double finYaw;

while (sdr.Read())

{

x1 = Convert.ToDouble(sdr["x1"].ToString());

y1 = Convert.ToDouble(sdr["y1"].ToString());

z1 = Convert.ToDouble(sdr["z1"].ToString());

x2 = Convert.ToDouble(sdr["x2"].ToString());

y2 = Convert.ToDouble(sdr["y2"].ToString());

z2 = Convert.ToDouble(sdr["z2"].ToString());

pipeLength = mCoordSys.GetDistanceEx(x1, y1, z1, x2, y2, z2);

mCoordSys.GetAimingAngles(x1, y1, z1, x2, y2, z2, out oYaw, out oPitch);

if ((double)oYaw < 180)

{

finYaw = (double)oYaw + 180;

}

else

{

finYaw = (double)oYaw - 180;

}

//这里是创建3Dobject的代码，创建圆柱体，可以进行贴图，输入一端的坐标，管径，管长度，圆柱形状逼近多边形的边数等

mTerra3DRegbase = mObjectManager.CreateCylinder(x1, y1, z1, pipeRadius, pipeLength, segmentNum, lineColor, fillOpacity, fillColor, HeightStyleCode.HSC_TERRAIN_ABSOLUTE,
iGround, "");

mTerra3DRegbase.SetPosition(x1, y1, z1, finYaw, 90 - (double)oPitch, 0.0, 7);

}



2.以图层方式添加，优势在于成组进行图层管理，图层的显示类型有很多种类，比如每个点位显示球形，圆柱形，3D模型等等，图层的属性中可以进行一定的更改。



//创建图层组

int iGround = mInformationTee.CreateGroup("管线layer",
0); ;

double x1 = 0, y1 = 0, z1 = 0;

double x2 = 0, y2 = 0, z2 = 0;

double pipeLength;

double pipeRadius = 2;

List Aname = new List();

IPosition6 currCoord, nextCoord;

SGWorld sgworld = new SGWorld();

//创建featurelayer

ILayer6 CylindresLayer = sgworld.Creator.CreateNewFeatureLayer("第一管线段",
LayerGeometryType.LGT_POINT, "FileName=pipes" + DateTime.Now.Day + ".shp;TEPlugName=OGR;", iGround);

//sdsdsd.Streaming = false;

//编辑layer属性，类似于在shp文件中设置字段属性，每一个点可以取得不同的值，再将其赋值给图层的属性中

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Yaw", AttributeTypeCode.AT_DOUBLE, 0);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Pitch", AttributeTypeCode.AT_DOUBLE, 0);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Roll", AttributeTypeCode.AT_DOUBLE, 0);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Texture", AttributeTypeCode.AT_TEXT, 1024);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Rotate", AttributeTypeCode.AT_DOUBLE, 100);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("RadiusX", AttributeTypeCode.AT_DOUBLE, 0);

CylindresLayer.DataSourceInfo.Attributes.CreateAttribute("Height", AttributeTypeCode.AT_DOUBLE, 0);

CylindresLayer.Visibility.MaxVisibilityDistance = 5000;

//编辑属性对应，如上图

CylindresLayer.FeatureGroups.Point.DisplayAs = ObjectTypeCode.OT_CYLINDER;

CylindresLayer.FeatureGroups.Point.SetProperty("Number of sides", 16);

CylindresLayer.FeatureGroups.Point.SetProperty("Line Opacity", 0);

CylindresLayer.FeatureGroups.Point.SetProperty("Fill Opacity", 100);

CylindresLayer.FeatureGroups.Point.SetProperty("Yaw", "[Yaw]");

CylindresLayer.FeatureGroups.Point.SetProperty("Roll", "[Roll]");

CylindresLayer.FeatureGroups.Point.SetProperty("Pitch", "[Pitch]");

CylindresLayer.FeatureGroups.Point.SetProperty("Texture File", "[Texture]");

CylindresLayer.FeatureGroups.Point.SetProperty("Rotate", "[Rotate]");

CylindresLayer.FeatureGroups.Point.SetProperty("Radius X", "[RadiusX]");

CylindresLayer.FeatureGroups.Point.SetProperty("Height", "[Height]");

//创建管段端外围

ILayer6 SpheresLayer = sgworld.Creator.CreateNewFeatureLayer("管段连接",
LayerGeometryType.LGT_POINT, "FileName=connectors" + DateTime.Now.Day + ".shp;TEPlugName=OGR;", iGround);

//SpheresLayer.Streaming = false;

SpheresLayer.Refresh();

SpheresLayer.DataSourceInfo.Attributes.CreateAttribute("Yaw", AttributeTypeCode.AT_DOUBLE, 0);

SpheresLayer.DataSourceInfo.Attributes.CreateAttribute("Pitch", AttributeTypeCode.AT_DOUBLE, 0);

SpheresLayer.DataSourceInfo.Attributes.CreateAttribute("Roll", AttributeTypeCode.AT_DOUBLE, 0);

SpheresLayer.FeatureGroups.Point.DisplayAs = ObjectTypeCode.OT_SPHERE;

SpheresLayer.FeatureGroups.Point.SetProperty("Yaw", "[Yaw]");

SpheresLayer.FeatureGroups.Point.SetProperty("Roll", "[Roll]");

SpheresLayer.FeatureGroups.Point.SetProperty("Pitch", "[Pitch]");

SpheresLayer.FeatureGroups.Point.SetProperty("Segment density", 16);

SpheresLayer.FeatureGroups.Point.SetProperty("Line Opacity", 0);

SpheresLayer.FeatureGroups.Point.SetProperty("Fill Opacity", 100);

SpheresLayer.FeatureGroups.Point.SetProperty("Radius", pipeRadius);

SpheresLayer.FeatureGroups.Point.SetProperty("Texture File", Application.StartupPath+@"\pipeTextureCyan2.bmp");

SpheresLayer.Visibility.MaxVisibilityDistance = 5000;

while (sdr.Read())

{

x1 = Convert.ToDouble(sdr["x1"].ToString());

y1 = Convert.ToDouble(sdr["y1"].ToString());

z1 = Convert.ToDouble(sdr["z1"].ToString());

x2 = Convert.ToDouble(sdr["x2"].ToString());

y2 = Convert.ToDouble(sdr["y2"].ToString());

z2 = Convert.ToDouble(sdr["z2"].ToString());

//创建点位

currCoord = sgworld.Creator.CreatePosition(x1, y1, z1);

nextCoord = sgworld.Creator.CreatePosition(x2, y2, z2);

currCoord = currCoord.AimTo(nextCoord);

currCoord.ChangeAltitudeType(AltitudeTypeCode.ATC_TERRAIN_RELATIVE); // Relative to terrain

pipeLength = currCoord.DistanceTo(nextCoord);

//管段绘制

var pitch = -90 + currCoord.Pitch;

CylindresLayer.FeatureGroups.Point.CreateFeature(new double[] { currCoord.X, currCoord.Y, currCoord.Altitude }, currCoord.Yaw + ";" + pitch + ";" + currCoord.Roll
+ ";" + texture + ";" + FixTextureAngle(pitch, 16) + ";" + pipeRadius + ";" + pipeLength);

//管端外围

var radius1 = pipeRadius * 1.1;

CylindresLayer.FeatureGroups.Point.CreateFeature(new double[] { currCoord.X, currCoord.Y, currCoord.Altitude }, currCoord.Yaw + ";" + pitch + ";" + currCoord.Roll
+ ";" + Application.StartupPath+@"\pipeTextureCyan.bmp" + ";" + FixTextureAngle(pitch, 16) + ";" + radius1 + ";" + radius1);

CylindresLayer.FeatureGroups.Point.CreateFeature(new double[] { nextCoord.X, nextCoord.Y, nextCoord.Altitude }, (180 + currCoord.Yaw) + ";" + pitch + ";"
+ currCoord.Roll + ";" + Application.StartupPath+@"\pipeTextureCyan.bmp" + ";" + FixTextureAngle(pitch, 16) + ";" + radius1 + ";" + radius1);

//绘制连接弯管（球代替），判断有连接则放置

string a1 = sdr["A1"].ToString();

string a2 = sdr["A2"].ToString();

if (Aname.Contains(a1))

{

currCoord.Altitude -= pipeRadius;

SpheresLayer.FeatureGroups.Point.CreateFeature(new double[] { currCoord.X, currCoord.Y, currCoord.Altitude }, currCoord.Yaw + ";"
+ currCoord.Pitch + ";" + currCoord.Roll);

Aname.Remove(a1);

else

{

Aname.Add(a1);

}

if (Aname.Contains(a2))

{

nextCoord.Altitude -= pipeRadius;

SpheresLayer.FeatureGroups.Point.CreateFeature(new double[] { nextCoord.X, nextCoord.Y, nextCoord.Altitude }, nextCoord.Yaw + ";"

Aname.Remove(a2);

}

else

{

Aname.Add(a2);

}

}

CylindresLayer.Save();

SpheresLayer.Save();



类似的，加载三维模型：



需要注意的是，在加载mpt之后，以图层方式加载管线显示不出来，只有在fly文件基础上才能看到。完整的程序可以在本人的CSDN中下载：http://download.csdn.net/detail/a1002308667/9487840
