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.
