+Description
+===========
+   The Pick sample shows how to implement "picking" which is finding which
+   triangle in a mesh is intersected by a ray. In this case, the ray comes 
+   from mouse coordinates.
+
+
+Path
+====
+   Source:     DXSDK\Samples\Multimedia\D3D\Pick
+   Executable: DXSDK\Samples\Multimedia\D3D\Bin
+
+
+User's Guide
+============
+   The following keys are implemented. The dropdown menus can be used for the
+   same controls.
+      <Enter>     Starts and stops the scene
+      <Space>     Advances the scene by a small increment
+      <F1>        Shows help or available commands.
+      <F2>        Prompts user to select a new rendering device or display mode
+      <Alt+Enter> Toggles between fullscreen and windowed modes
+      <Esc>       Exits the app.
+   
+   Use the mouse to "pick" any spot in the mesh to see that triangle.
+
+
+Programming Notes
+=================
+   When the user clicks the mouse, the code reads the screen coordinates of the 
+   cursor.  These coordinates are converted, via the projection and view matrices,
+   into a ray which goes from the eye point through the point clicked on the screen
+   and into the scene.  This ray is passed to IntersectTriangle along with each
+   triangle of the loaded model to determine which triangles, if any, are 
+   intersected by the ray.  The texture coordinates of the intersected triangle
+   is also determined.
+
+   This sample makes use of common DirectX code (consisting of helper functions,
+   etc.) that is shared with other samples on the DirectX SDK. All common
+   headers and source code can be found in the following directory:
