방법: 3D 모델의 배율 변환

  • 아티클

이 예제에서는 3D 개체를 스케일링하는 방법을 보여 줍니다. 3D 개체를 스케일링하려면 ScaleTransform3D를 사용합니다. ScaleX, ScaleY 및 ScaleZ 속성은 지정한 요인별로 요소의 크기를 조정합니다. 예를 들어, 1.5의 ScaleX 값은 개체를 원래 너비의 150%까지 확장합니다. 0.5의 ScaleY 값은 개체의 높이를 50%로 줄입니다. 아래 코드는 GeometryModel3D에 대한 변환으로 ScaleTransform3D 사용을 보여 줍니다.

<!-- 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>
