的Viewport3D：如何从代码上创建一个WPF对象（立方）文本背后(ViewPort3D: Ho

我想画一组三维立方体，每个立方体应该显示的名称，并选择了多维数据集时应该有自己的事件处理程序。

是否有可能使用后面的代码或XAML绑定来实现呢？

从代码中绘制一个3D立方体后面我会用Helix3D工具包CubeVisual3D。但是，如果你要坚持用WPF股票3D元素它是实现相当简单。

从这里开始，了解3D文字enviroments http://www.codeproject.com/Articles/33893/WPF-Creation-of-Text-Labels-for-3D-Scene将引导您通过两个不同的方法来添加文本3D图像，我觉得非常有帮助。

对于一个立方体就使用这样的RectangleVisual3D对象的东西。

    RectangleVisual3D myCube = new RectangleVisual3D();
    myCube.Origin = new Point3D(0, 0, 0); //Set this value to whatever you want your Cube Origen to be.
    myCube.Width = 5; //whatever width you would like.
    myCube.Length = 5; //Set Length = Width
    myCube.Normal = new Vector3D(0, 1, 0); // if you want a cube that is not at some angle then use a vector in the direction of an axis such as this one or <1,0,0> and <0,0,1>
    myCube.LengthDirection = new Vector3D(0, 1, 0); //This will depend on the orientation of the cube however since it is equilateral just set it to the same thing as normal.
    myCube.Material = new DiffuseMaterial(Brushes.Red); // Set this with whatever you want or just set the myCube.Fill Property with a brush type.

太添加事件处理，我相信你一定的处理程序添加到的Viewport3D。这种性质的东西应该工作。

    public Window1()
    {
    InitializeComponent();
    this.mainViewport.MouseDown += new MouseButtonEventHandler(mainViewport_MouseDown);
    this.mainViewport.MouseUp += new MouseButtonEventHandler(mainViewport_MouseUp);
    }

然后添加此功能

    ModelVisual3D GetHitResult(Point location)
    {
    HitTestResult result = VisualTreeHelper.HitTest(mainViewport, location);
    if(result != null && result.VisualHit is ModelVisual3D)
    {
    ModelVisual3D visual = (ModelVisual3D)result.VisualHit;
    return visual;
    }

    return null;
    }

然后添加在事件处理程序

    void mainViewport_MouseUp(object sender, MouseButtonEventArgs e)
    {
    Point location = e.GetPosition(mainViewport);
    ModelVisual3D result = GetHitResult(location);
    if(result == null)
    {
    return;
    }
    //Do Stuff Here
    }

    void mainViewport_MouseDown(object sender, MouseButtonEventArgs e)
    {
    Point location = e.GetPosition(mainViewport);
    ModelVisual3D result = GetHitResult(location);
    if(result == null)
    {
    return;
    }
    //Do Stuff Here
    }
