先下载SDK：https://pan.baidu.com/s/1M9kBS6ouUwLfrt0zV0bPew 密码：1te1

地图数据包（sqlserver2008R2版本，也可以不下载）：??https://pan.baidu.com/s/1PjcNamad7OVpCrsVJ7dwFQ 密码：uw9r

下载核心SDK升级包：https://pan.baidu.com/s/1Q3dlM-Va-RmlEYbnmi8Xuw?并覆盖到SDK目录中。里面有也每一篇的例子代码

完整的视频演示：http://v.youku.com/v_show/id_XMTU4MTI5NTE4NA==.html

下载完成以后，解压出来，将30-1.exe 拖动到?把授权拖到我上面install.bat上完成授权安装。。。

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：技术分享图片

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：
