 New Content 
  
  Stencil Based Screen Wipes 
  
   Illustrates the application of an 
  alpha mask to the stencil buffer, and the use of this technique to create 
  complex screen wipes between scenes.  
  Includes sample application with source code and media. 
  
  Rendering 3D Scenes to Large 
  Image Formats  
  
   In this article we examine 
  a technique for rendering very large images in Direct3D, 
  independent of available video memory.  This  
  can be extremely useful if you need to generate artwork for print - blowing up 
  a screen grab to poster size just doesn't cut it! 
  Includes sample source code.  
  
  Saving a Screen Shot in 
  DirectX Graphics 
  
  With the release of the 
  DirectX 8.1 SDK, new functions were introduced to the D3DX libraries providing 
  pre-canned routines to write image files from DirectX resources.  In this 
  article, we will examine a function to save a screen shot from an 
  application as a BMP or DDS file.
