Description
===========
This sample shows some of the effects that can be achieved using vertex
shaders. Vertex shaders use a set of instructions, executed by the 3D
device on a per-vertex basis, that can affect the properties of the
vertex (positions, normal, color, tex coords, etc.) in interesting ways.
Note that not all cards may support all the various features vertex shaders.
For more information on vertex shaders, 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
<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.
Programming Notes
=================
Programming vertex shaders is not a trivial task. Please read any vertex
shader-specific documentation accompanying the DirectX SDK.
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:
