<h3 align="left">This control has the following features:</h3>
<ul>
<li><h4 align="left">A 3D vector MFC control derived from CButton.</h4>
</li>
<li><h4 align="left">Real-time light rendering on a 3D ball.</h4>
</li>
<li><h4 align="left">Variable ball radius and position.</h4>
</li>
<li><h4 align="left">Supports bitmap background (tiled).</h4>
</li>
<li><h4 align="left">Supports vertical gradient color background (from color to color, as visiable in screen capture above).</h4>
</li>
<li><h4 align="left">Variable ball color (diffuse), light color and ambient color.</h4>
</li>
<li><h4 align="left">Variable specular intensity.</h4>
</li>
<li><h4 align="left">Supports attached controls (for automatic update).<br>
That is, you can specify IDs of other controls that will reflect (textually) the value of
a specific vector component. The vector control will automatically update (calling
SetwindowText) the display. See the 3 static text controls in the example above.</h4>
</li>
<li><h4 align="left">Variable mouse sensitivity.</h4>
</li>
<li><h4 align="left">Supports front clipping (vector will not have negative Z values).</h4>
</li>
<li><h4 align="left">Supports callback functions for the following events:<br>
1. The trackball has moved (vector is changing).<br>
2. The user dropped the trackball (released left mouse button). i.e., the vector was
changed.<br>
</h4>
</li>
</ul>
