Description
===========
The Text3D sample shows how to draw 2D text and 3D text in a 3D scene. This
is most useful for display stats, in game menus, etc.

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
=================
This sample uses the common class, CD3DFont, to display 2D text in a 3D
scene. The source code for the class can be found in the "common" directory
(described below), and is of most interest to this sample. The class uses
GDI to load a font and output each letter to a bitmap. That bitmap, in turn,
is used to create a texture.
When the CD3DFont class' DrawText() function is called, a vertex buffer is
filled with polygons that are textured using the font texture created as
mentioned above. The polygons may be drawn as a 2D overlay (useful for
printing stats, etc.) or truly integrated in the 3D scene.
The sample also shows how to use D3DXCreateText() to create a D3DX mesh
containing a 3D model of a text string. Note that D3DXCreateText may not
work with certain types of fonts, such as bitmap fonts and some symbol fonts.
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:
