将旋转/平移到按钮meshgeometry3d wpf c＃

Question

我对wpf和c＃还很新，我正在做一个关于旋转，网格平移的项目。

我在XAML中创建了网格，看起来一切正常。这是当我尝试编程旋转/平移按钮，我有问题。由于大部分代码都在XAML中，我猜想旋转也应该在XAML中，但我无法找到将旋转附加到按钮的方式。我刚刚找到了一些示例，展示如何旋转并非我想要的按钮。 所以我想知道是否有办法在XAML中做到这一点，或者我需要在* .cs文件中传输网格的所有位置和索引。

这里是我的XAML代码：

</Grid> 
</Window> 

以下是我在* .cs文件的尝试：

namespace WpfApplication16 
{ 
    /// <summary> 
    /// Interaction logic for MainWindow.xaml 
    /// </summary> 
    public partial class MainWindow : Window 
{ 
    AxisAngleRotation3D rotx; 

    public MainWindow() 
    { 
     InitializeComponent(); 

     rotx = new AxisAngleRotation3D(new Vector3D(1, 0, 0), 10); 

    } 

    MeshGeometry3D myGeometryModel = new MeshGeometry3D(); 

    private void button_click(object sender, RoutedEventArgs e) 
    { 

     //GeometryModel3D.Transform = new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(1, 0, 0), angle += 10)); 

     rotx.Angle += 10; 
     rotate.Angle += 10; 
     rotate1.Angle += 10; 

     RotateTransform3D myRotateTransform3D = new RotateTransform3D(); 
     AxisAngleRotation3D myAXisAngleRotation3d = new AxisAngleRotation3D(); 
     myAXisAngleRotation3d.Axis = new Vector3D(1, 0, 0); 
     myAXisAngleRotation3d.Angle = 10; 
     myRotateTransform3D.Rotation = myAXisAngleRotation3d; 

     Transform3DGroup myTransform3Dgroup = new Transform3DGroup(); 
     myTransform3Dgroup.Children.Add(myRotateTransform3D); 

     myGeometryModel.Transform = myTransform3Dgroup; 


    } 
} 
} 

这是第一个按钮一试，我想围绕X轴做10度的旋转。它不工作。

结果是在最后一行说错误。 Transform is not a method group。其他按钮将用于绕Y轴旋转。另外3个用于在3轴方向x，y，z上平移1个单位。

同样，我可以使用我在XAML中声明的内容，或者我需要将这些信息输入到* .cs文件中？

这可能是一个非常简单的答案，但就像我说的我是新手。所以先谢谢了。

更改您的XAML变换到这一点：

<GeometryModel3D.Transform> 
    <Transform3DGroup> 
     <RotateTransform3D> 
      <RotateTransform3D.Rotation> 
       <AxisAngleRotation3D x:Name="rotate" Axis="1 0 0" Angle="10"/> 
      </RotateTransform3D.Rotation> 
     </RotateTransform3D> 
     <RotateTransform3D> 
      <RotateTransform3D.Rotation> 
       <AxisAngleRotation3D x:Name="rotatey" Axis="0 1 0" Angle="0"/> 
      </RotateTransform3D.Rotation> 
     </RotateTransform3D> 
     <TranslateTransform3D x:Name="translate" OffsetX="0" OffsetY="0" OffsetZ="0" /> 
    </Transform3DGroup> 
</GeometryModel3D.Transform> 

同样地，对于蓝网：

<GeometryModel3D.Transform> 
    <Transform3DGroup> 
     <RotateTransform3D> 
      <RotateTransform3D.Rotation> 
       <AxisAngleRotation3D x:Name="rotate1" Axis="1 0 0" Angle="10"/> 
      </RotateTransform3D.Rotation> 
     </RotateTransform3D> 
     <RotateTransform3D> 
      <RotateTransform3D.Rotation> 
       <AxisAngleRotation3D x:Name="rotatey1" Axis="0 1 0" Angle="0"/> 
      </RotateTransform3D.Rotation> 
     </RotateTransform3D> 
     <TranslateTransform3D x:Name="translate1" OffsetX="0" OffsetY="0" OffsetZ="0" /> 
    </Transform3DGroup> 
</GeometryModel3D.Transform> 

再用线向上按钮点击此：

private void button_click(object sender, RoutedEventArgs e) 
{ 
    rotate.Angle += 10; 
    rotate1.Angle += 10; 
} 
private void button1_Click(object sender, RoutedEventArgs e) 
{ 
    rotatey.Angle += 5; 
    rotatey1.Angle += 5; 
} 
private void button2_Click(object sender, RoutedEventArgs e) 
{ 
    translate.OffsetX += 1; 
    translate1.OffsetX += 1; 
} 
private void button3_Click(object sender, RoutedEventArgs e) 
{ 
    translate.OffsetY += 1; 
    translate1.OffsetY += 1; 
} 
private void button4_Click(object sender, RoutedEventArgs e) 
{ 
    translate.OffsetZ += 1; 
    translate1.OffsetZ += 1; 
} 

我希望有所帮助。
