将滑块绑定到WPF中XAML中的3D线移动动作

如何解决将滑块绑定到WPF中XAML中的3D线移动动作

我已经在Windows 7中使用C＃构建了WPF 3D项目。 我刚刚创建了2个滑块（垂直和水平）和2条3D线（垂直和水平），想要分别将滑块绑定到3D线移动动作。

XAML：

<UserControl x:Class="STIGenericReport.UserControl"

    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height ="574*" />
        <RowDefinition Height="26" MinHeight="16" />
    </Grid.RowDefinitions>
    <Viewport3D Name="mainViewport" ClipToBounds = "False"  
                IsHitTestVisible="false"
                RenderOptions.EdgeMode="Aliased" Margin="12,52,144,47">
        <Viewport3D.Camera>
            <OrthographicCamera x:Name="camera" Width="2"

                NearPlaneDistance="1" 
                LookDirection="0,-1"
                UpDirection="0,1,0"
                Position="0,2" />
        </Viewport3D.Camera>
        <Viewport3D.Children>
            <ModelVisual3D x:Name="Light1">
                <ModelVisual3D.Content>
                    <DirectionalLight Color="White" Direction="1,-1" />

            </ModelVisual3D>

            <ModelVisual3D x:Name="Light3">
                <ModelVisual3D.Content>
                    <DirectionalLight Color="White" Direction="0,-1,-0.5" />
                </ModelVisual3D.Content>
            </ModelVisual3D>
            <tool3d:ScreenSpaceLines3D Points ="0,100,-100,0" Color="Black" Thickness="2"/>

                <TranslateTransform/>
            </TransformGroup>
        </Slider.RenderTransform>
    </Slider>
</Grid>

  namespace _3DTools
  {
  public class ScreenSpaceLines3D : ModelVisual3D
  {
    public static readonly DependencyProperty ColorProperty;
    public static readonly DependencyProperty ThicknessProperty;
    public static readonly DependencyProperty PointsProperty;

    public ScreenSpaceLines3D();

    public Color Color { get; set; }
    public double Thickness { get; set; }
    public Point3DCollection Points { get; set; }

    public void MakeWireframe(Model3D model);
   }
}

我要实现此功能： 当我移动水平滑块时，垂直线水平移动； 当我移动垂直滑块时，水平线垂直移动。

如何添加这种绑定？我尝试使用普通方法，但失败了。

解决方法

为水平滑块提供一个最小值和最大值：

%x = alloca fp128
store fp128 0xLE978D4FDF3B645A24000921CAC083126,fp128* %x

然后将转换偏移量应用于水平线，将OffsetY绑定到滑块的值：

<Slider x:Name="slider" Minimum="-1" Maximum="1" HorizontalAlignment="Left" Margin="20,357,0" VerticalAlignment="Top" Width="484" />

重复另一个轴。
