WPF旋转按钮 [英] WPF rotating button

问题描述

帮我PLZ。我需要在动画z轴按钮的旋转，而无需使用外部库，只能用C＃和XAML code。

Help me plz. I need to animate rotation of the button on z-axis without using external libraries, only with C# and xaml code.

这可能吗？我该怎么做？

Is that possible? How can I do that?

感谢。

推荐答案

在看一看<一个href=\"http://msdn.microsoft.com/en-us/library/system.windows.media.media3d.viewport2dvisual3d.aspx\">Viewport2DVisual3D

在链接的例子正是这么做的。

The example in the link does exactly that.

编辑：这是从与Z轴的加动画链接的例子

Here is the example from the link with an added animation of the Z axis

的貌似这个的结果

Looks like this

<Viewport3D>
    <Viewport3D.Camera>
        <PerspectiveCamera Position="0, 0, 4"/>
    </Viewport3D.Camera>
    <Viewport2DVisual3D x:Name="v2dv3d">
        <Viewport2DVisual3D.Transform>
            <RotateTransform3D>
                <RotateTransform3D.Rotation>
                    <AxisAngleRotation3D Angle="0" Axis="0, 1, 0" />
                </RotateTransform3D.Rotation>
            </RotateTransform3D>
