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>
