title: Want to make object transparent
body: <p>I am working with directx. I am displaying two objects on my window. They are intersecting each other. I find the intersecting object.  </p>
  
  <p>My problem is-<br>
  I want two original objects to be transparent and the resulting intersected part to be   opaque, so that the intersected part can be seen clearly.  </p>
  
  <p>I found some question related to transparency but they are related to transparency of window. But I want the object to be transparent.</p>
