<h2>Presentation</h2>
libQGLViewer is a C++ library based on Qt that eases the creation of OpenGL 3D viewers.
<p>
It provides some of the typical 3D viewer functionalities, such as the possibility to move the
camera using the mouse, which lacks in most of the other APIs. Other features include mouse
manipulated frames, interpolated keyFrames, object selection, stereo display, screenshot saving and
<a href="features.html">much more</a>. It can be used by OpenGL beginners as well as to create
complex applications, being fully customizable and easy to extend.
</p>
Based on the Qt toolkit, it compiles on any architecture (Unix-Linux, Mac, Windows).
Full <a href="refManual/hierarchy.html">reference documentation</a> and many <a
href="examples/index.html">examples</a> are provided. libQGLViewer does <i>not</i> display 3D scenes
in various formats, but it can be the base for the coding of such a viewer.
<p>
libQGLViewer uses <a href="dualLicensing.html">dual licensing</a>: it is
freely available under the terms of the GNU-GPL license for open source software development, while
commercial applications can apply for a <a href="mailto:contact@libqglviewer.com?Subject=Commercial license">commercial license</a>.
</p>
Over <a href="download_statistics.html">400 downloads</a> are recorded each month.
