/**同一级别的其他要素**/

我想通过C访问Transform3DGroup x:Key=“root\u boneOR13TR12”元素# 并希望根据需要修改AxisAngelRotation属性

真诚地，
bbklol

让我们从定义故事板开始：当您运行它时，它实际上会旋转您的对象

然后，通过一些动画（同样
DoubleAnimation
工作正常），您可以设置RotateTransform3D的旋转属性（见下文）

在您的情况下，为了回答您的问题，我认为您应该使用与此非常接近的语法（我保留了您的XAML路径，用
[]
…删除它们！！）：

我给你举个例子，也许你可以用一种更简单的方式来理解

这是一个情节提要，它将旋转下面
视口3D
中的项目：

<Storyboard x:Key="RotationStoryboard">
    <!--This is an horizontal rotation-->
    <DoubleAnimation Storyboard.TargetProperty="(Viewport3D.Children)[0].(ModelVisual3D.Transform).(Transform3DGroup.Children)[0].(RotateTransform3D.Rotation).(AxisAngleRotation3D.Angle)"
        BeginTime="0:0:0.25"
        From="360"
        To="0"
        Duration="0:0:4.5"
        RepeatBehavior="Forever" />
    <!--This is an orbital horizontal rotation (I removed the other rotation on first transformation)-->
    <DoubleAnimation Storyboard.TargetProperty="(Viewport3D.Children)[1].(ModelVisual3D.Transform).(Transform3DGroup.Children)[3].(RotateTransform3D.Rotation).(AxisAngleRotation3D.Angle)"
        From="360"
        To="0"
        RepeatBehavior="Forever"
        Duration="0:0:3.5" />
</Storyboard>
这是对象的XAML代码

Transform=“{Binding root\u boneOR13TR12}”等转换绑定，然后在InitilizeComponents（）之前在代码中创建Transform3DGroup，然后更新它应该会更新视图（我不记得转换是使用依赖性道具还是普通道具）。耶！非常感谢你。在我读了一篇关于数据绑定的德语教程后，我知道如何处理它（是的，但我认为你已经接近解决方案了…看看我的答案！
