问题描述
大家好
我有一个窗口项目，并在"ViewPort3D"中使用.它包括使用"ViewPort2DVisual3D"对象和"ModelVisual3D"对象的UserControl.
但是我无法将"EpacingFunction"(在每个KeyFrame中)的不透明度"动画设置为"ViewPort2DVisual3D" +"ModelVisual3D".
换句话说，"ViewPort2DVisual3D"的关键帧中没有"EasingFunction"，而"ModelVisual3D"具有它.
如何在Expression Blend中在每个KeyFrame上设置"EasingFunction"(例如反弹")效果并对其进行动画处理(ViewPort2DVisual3D和ModelVisual3D)?
请给我您的解决方案和想法.
提前谢谢.

我的xaml代码是:
Hi everybody
I have a window project and use within a "ViewPort3D". It is include a UserControl using "ViewPort2DVisual3D" object and a "ModelVisual3D" object.
But I can''t set animate "Opacity" with "EasingFunction" (in each KeyFrame) to "ViewPort2DVisual3D" + "ModelVisual3D".
In other words, "ViewPort2DVisual3D" not able to have "EasingFunction" in its KeyFrames, but "ModelVisual3D" have it.
How to set "EasingFunction" such as "bounces" effect on each KeyFrame and animate them (ViewPort2DVisual3D and ModelVisual3D) together in Expression Blend?
Please give me any your solution and ideas.
Thanks in advance.
