OVERVIEW

    This was a GLUT 3.7-based demo of the OpenGL Shading Language.  It
    includes a vertex shader/fragment shader pair that procedurally
    generates a brick pattern. These shaders are the shaders that are
    described in Chapter 6 of the book, OpenGL Shading Language, published
    by Addison-Wesley. In addition, this demo includes the application
    source code that is included and described in Chapter 7 of this book.

    When launched, ogl2brick loads, compiles, and links the brick shaders,
    then installs them as part of current state. Keyboard commands for this
    demo are:

    /* b - Toggle among background clear colors */
    /* q, */ <esc> - Quit
    /* t - Toggle among models to render */
    /* ? - Help */
    /* <home>     - reset zoom and rotation */
    /* <space> or <click>        - stop rotation */
    /* <+>, <-> or <ctrl + drag> - zoom model */
    m wheel up/down - zoom model
    /* <arrow keys> or <drag>    - rotate model */
    mlbutton + mmove - rotate model

    /*
     * Be sure to cycle through the different models (box, teapot, sphere,
     * torus) using the "t" key in order to see how this shader looks on
     * different models.
     */
    The application prints various diagnostic and InfoLog messages to the
    console window when building and applying GLSL shaders.

    /*
     * This application can be compiled and linked using the VisualStudio.net
     * solution file that is included (ogl2brick.sln).
     */
    Under Win32 this app can be compiled at least with VS6 / NET2005 / WATCOM
    Under Linux there is a problem with NV GLSL compiler. :{
