设置system.ini 如下内容

Server=122.112.229.220

user=GisTest

Password=chinamtouch.com

该数据库中只提供 成都市火车南站附近的数据请注意,104.0648,30.61658

利用三方工具,如幻影粒子:

或者flash一类的工具生成如下的PNG序列:

然后下面利 用https://blog.csdn.net/xtgmd168/article/details/85264680 中所介绍的方法。将它变成一个简单的粒子显示元素:

新建一个UserControl完成序列PNG的动态显示:

AmiImage.xaml

AmiImage.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

using System.IO;

namespace Teach3DGIS

{

///

/// AmiImage.xaml 的交互逻辑

///

public partial class AmiImage : UserControl

{

public AmiImage()

{

InitializeComponent();

}

private List FileList = new List();

private System.Windows.Threading.DispatcherTimer ATimer;

private int index = 0;

public AmiImage(string Path)

{

InitializeComponent();

DirectoryInfo v1 = new DirectoryInfo(Path);

foreach(FileInfo V2 in v1.GetFiles("*.png"))

{

FileList.Add(V2.FullName);

}

ATimer = new System.Windows.Threading.DispatcherTimer();

ATimer.Tick += ATimer_Tick;

ATimer.Interval = new TimeSpan(0, 0, 0, 0,5);

ATimer.Start();

}

private void ATimer_Tick(object sender, EventArgs e)

{

this.Background = new ImageBrush(new BitmapImage(new Uri(FileList[index])));

index++;

if (index == FileList.Count - 1)

index = 0;

}

}

}

主程序中代码如下:

private void Button_Click_9(object sender, RoutedEventArgs e)

{

gis3d.GetJWEvent += Gis3d_GetJWEvent1;

gis3d.State = GisLib.WindowsMT.GisState.获取经纬度;

}

private void Gis3d_GetJWEvent1(System.Windows.Media.Media3D.Point3D value)

{

gis3d.GetJWEvent -= Gis3d_GetJWEvent;

gis3d.State = GisLib.WindowsMT.GisState.漫游;

AmiImage y1 = new AmiImage(AppDomain.CurrentDomain.BaseDirectory + "a");

NewGisBiao.M3D.UserGisUI3dObject2 JuLiSechBiao = new NewGisBiao.M3D.UserGisUI3dObject2(); //新建一个承载UI对象的东东

JuLiSechBiao.PareantEarth = (NewGisBiao.Base.GISInterfaseForBiao)IniRead.IniReadWrite.MPareant;//设置它的GIS球对象

JuLiSechBiao.Manage = IniRead.IniReadWrite.BiaoManage;//设置它的标号管理器

JuLiSechBiao.MaxZoom = 9;//最大显示层,当小于9层的时候不显示

JuLiSechBiao.MUIValue = y1;//UI对象

JuLiSechBiao.DHi = 0.01;//相对于地形的高度

JuLiSechBiao.ZScal = 0.6;//相对缩放

JuLiSechBiao.Scal.ScaleX = 1; //固定东东

JuLiSechBiao.Scal.ScaleY = 1;

JuLiSechBiao.Scal.ScaleZ = 1;

JuLiSechBiao.AutoScal = true;//是否自动缩放,不管在哪一层都是一样大

JuLiSechBiao.AutoAngle = true;//是否自动角度,使终对着摄像机

JuLiSechBiao.CenterType = JunBiao.CenteType.左下角;//中心点类型

IniRead.IniReadWrite.BiaoManage.AddJunBiao(JuLiSechBiao);//增加到军标管理对象中。也可以不加

JuLiSechBiao.MWidth = 250;//三维面片的大小

JuLiSechBiao.MHeight = 150;

JuLiSechBiao.MRX = 90;

if (IniRead.IniReadWrite.MPareant is MTGIS3D) //手动刷新一下自动角度。。。bug

{

((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxisAngleX.Angle += 0.001;

((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxisAngleX.Angle -= 0.001;

}

JuLiSechBiao.Center = new Point(value.X, value.Y);//设置中心点

JuLiSechBiao.ISShow = true;//显示

}

效果如下:

当然有一些效果是平贴在地上的,如光圈效果等:如下:

这里很明显就是用了两个对象,两个UI。其中一个UI的autoangle为false再通过调整 MRX MRY 设置一个死的角度就成上面这样了。效果还不错吧。WPF可以让我们尽情的发挥UI的优势。
