<p>
<p><h2> Introduction
</h2>
<aname="1"></a><p> OpenGL is a standard API for rendering 3D graphics.
<p> OpenGL only deals with 3D rendering and provides little or no support
for GUI programming issues. The user interface for an
OpenGL<sup>*</sup> application must be created with another toolkit,
such as <ahref="motif-extension.html#Motif">Motif</a> on the X platform, Microsoft Foundation Classes (MFC)
under Windows, or TQt on <em>both</em> platforms.
<p> The TQt OpenGL module makes it easy to use OpenGL in TQt applications.
It provides an OpenGL widget class that can be used just like any
other TQt widget, except that it opens an OpenGL display buffer where
you can use the OpenGL API to render the contents.
<p> The TQt OpenGL module is implemented as a platform-independent TQt/C++
wrapper around the platform-dependent GLX, WGL, or AGL C APIs. The
functionality provided is very similar to Mark Kilgard's GLUT library,
but with much more non-OpenGL-specific GUI functionality, i.e. the
whole TQt API.
<p><h2> Installation
</h2>
<aname="2"></a><p> When you install TQt for X11, the configure script will autodetect if
OpenGL headers and libraries are installed on your system, and if so,
it will include the TQt OpenGL module in the TQt library. (If your
OpenGL headers or libraries are placed in a non-standard directory,
you may need to change the QMAKE_INCDIR_OPENGL and/or
QMAKE_LIBDIR_OPENGL in the config file for your system). Some
