This topic demonstrates how to animate a translation transformation set on a 3-D model.

The code below shows the application of a TranslateTransform3D object to the Transform property of a GeometryModel3D.

<!-- The Transform specifies how to transform the 3D object. The OffsetX property is animated
     in the Storyboard below. -->
<GeometryModel3D.Transform>
  <TranslateTransform3D x:Name="myTranslateTransform3D" OffsetX="0" OffsetY="0" OffsetZ="0" />
</GeometryModel3D.Transform>

The OffsetX property of this TranslateTransform3D object is animated using the code below.

<!-- Trigger the TranslateTransform3D animation when the 3D object loads. -->
<Viewport3D.Triggers>
  <EventTrigger RoutedEvent="Viewport3D.Loaded">
    <BeginStoryboard>
      <Storyboard>

        <!-- This animation animates the OffsetX property of the TranslateTransform3D. -->
        <DoubleAnimation
         Storyboard.TargetName="myTranslateTransform3D" 
         Storyboard.TargetProperty="OffsetX" 
         To="-0.8" 
         AutoReverse="True" RepeatBehavior="Forever" />

        <!-- If you want to animate OffsetY and/or OffsetZ, create similar DoubleAnimations
             respectively. -->

      </Storyboard>
    </BeginStoryboard>
  </EventTrigger>
</Viewport3D.Triggers>

The following code shows the entire sample.
