+Description
+===========
+   The SphereMap sample demonstrates an enviroment-mapping technique called 
+   sphere-mapping. Environment-mapping is a technique in which the environment
+   surrounding a 3D object (such as the lights, etc.) are put into a texture
+   map, so that the object can have complex lighting effects without expensive
+   lighting calculations.
+
+   Note that not all cards support all features for all the various environment
+   mapping techniques (such as cubemapping and projected textures). For more
+   information on environment mapping, cubemapping, and projected textures, 
+   refer to the DirectX SDK documentation.

+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
+      <F2>        Prompts user to select a new rendering device or display mode
+      <Alt+Enter> Toggles between fullscreen and windowed modes
+      <Esc>       Exits the app.
+
+
+Programming Notes
+=================
+   Sphere-mapping uses a precomputed (at model time) texture map which contains
+   the entire environment as reflected by a chrome sphere. The idea is to
+   consider each vertex, compute it's normal, find where the normal matches up
+   on the chrome sphere, and then assign that texture coordinate to the vertex.
+
+   The math involves computations for each vertex for every frame.  This sample 
+   uses a vertex shader to perform these calculations.  Basically, the vertex 
+   shader computes a camera-space reflection vector, given the camera position, 
+   vertex position, and vertex normal.  Then, it computes the half-angle vector 
+   between the reflection vector, and the view direction.  This vector can then 
+   be scaled and offset by 0.5 to index into the spheremap texture.
+
+   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:
