This example shows how to scale a 3-D object. To scale a 3-D object, use a ScaleTransform3D. The ScaleX, ScaleY, and ScaleZ properties resize the element by the factor you specify. For example, a ScaleX value of 1.5 stretches an object to 150 percent of its original width. A ScaleY value of 0.5 shrinks the height of an object by 50 percent. The code below shows using a ScaleTransform3D as the transform for a GeometryModel3D.

<!-- Apply a scale transform to the object. You can transform the scale of the object
     for the X, Y, or Z axis. The ScaleX, ScaleY, and ScaleZ properties resize the object 
     by the factor you specify. For example, a ScaleX value of 1.5 stretches the object to 
     150 percent of its original width. A ScaleY value of 0.5 shrinks the height of an object 
     by 50 percent. -->
<GeometryModel3D.Transform>

  <!-- This Scale Transform stretches the object horizontally by 200 percent and shrinks it 
       vertically by 50 percent. -->
  <ScaleTransform3D ScaleX="2" ScaleY="0.5" ScaleZ="1" CenterX="0" CenterY="0" CenterZ="0" />
</GeometryModel3D.Transform>

The following code shows the entire sample.
