3DRotation的Model3DGroup

我有一個model3dgroup變換應用它看起來像這樣，3DRotation的Model3DGroup

<Transform3DGroup x:Key="B3OR34TR33"> 
       <TranslateTransform3D OffsetX="0" 
             OffsetY="-1.5748" 
             OffsetZ="-8.10376e-011" /> 
       <ScaleTransform3D ScaleX="1" 
            ScaleY="0.750021" 
            ScaleZ="1" /> 
       <RotateTransform3D> 
        <RotateTransform3D.Rotation> 
         <AxisAngleRotation3D Angle="90.0000025" 
              Axis="1 0 0" /> 
        </RotateTransform3D.Rotation> 
       </RotateTransform3D> 
       <TranslateTransform3D OffsetX="0" 
             OffsetY="0.0259444" 
             OffsetZ="5.51401" /> 
      </Transform3DGroup>

還有哪些動畫上加載的model3dgroup的動畫。

<DoubleAnimationUsingKeyFrames 
              BeginTime="0:0:0" 
              Duration="0:0:0.9" 
              Storyboard.TargetName="B3OR34" 
              Storyboard.TargetProperty="(Model3D.Transform).(Transform3DGroup.Children)[3].(TranslateTransform3D.OffsetX)"> 
       <LinearDoubleKeyFrame KeyTime="0:0:0" 
             Value="-38.50234985" /> 
       <LinearDoubleKeyFrame KeyTime="0:0:0.9" 
             Value="0" /> 
      </DoubleAnimationUsingKeyFrames> 
      <DoubleAnimationUsingKeyFrames 
              BeginTime="0:0:0" 
              Duration="0:0:0.9" 
              Storyboard.TargetName="B3OR34" 
              Storyboard.TargetProperty="(Model3D.Transform).(Transform3DGroup.Children)[3].(TranslateTransform3D.OffsetY)"> 
       <LinearDoubleKeyFrame KeyTime="0:0:0" 
             Value="0.02594435215" /> 
       <LinearDoubleKeyFrame KeyTime="0:0:0.9" 
             Value="0" /> 
      </DoubleAnimationUsingKeyFrames> 
      <DoubleAnimationUsingKeyFrames 
              BeginTime="0:0:0" 
              Duration="0:0:0.9" 
              Storyboard.TargetName="B3OR34" 
              Storyboard.TargetProperty="(Model3D.Transform).(Transform3DGroup.Children)[3].(TranslateTransform3D.OffsetZ)"> 
       <LinearDoubleKeyFrame KeyTime="0:0:0" 
             Value="5.514007568" /> 
       <LinearDoubleKeyFrame KeyTime="0:0:0.9" 
             Value="0" /> 
      </DoubleAnimationUsingKeyFrames>

的model3dgroup是用5個幾何[頂部，底部，前部，後部&側]的立方體。問題是，當我應用一個行爲roatate model3dgroup時，旋轉發生在geometrymodel3d之一的x軸的中間。我應該在這裏看到關於model3dgroup的中心旋轉。

您可以設置與的centerX/Y/Z屬性

在你的情況下，中心RotateTransform3D的中心已經成爲您的應用翻譯

  <RotateTransform3D CenterX="0" 
           CenterY="-1.5748" 
           CenterZ="-8.10376e-011" />
