<h2>GL Driver</h2>
- <p>This driver represents a basic driver for all system-dependent drivers
- implemented in the X-Windows system using the <a href="http://www.opengl.org/">
- OpenGL</a> SDK. The implementation uses the OpenGL, GLU and GLX API functions.
+ <p>This driver represents a driver for drawing using
+ <a href="http://www.opengl.org/">
+ OpenGL</a>. The implementation uses the OpenGL functions only.
For the font support, this driver uses the
<a href="http://homepages.paradise.net.nz/henryj/code/index.html#FTGL">FTGL</a>
API functions, which it was written against the
<a href="http://www.freetype.org/">Free Type</a> library.</p>
+<p>The driver is not dependent of system functions. It uses only the OpenGL
+portable funtions. So if the window canvas changes its size the attribute &quot;SIZE&quot;
+must be set with the new size or cdCanvasGetSize will return an incorrect value.</p>
+
+<h3>Use</h3>
+
+ <p>The canvas is created by means of a call to the function <font face="Courier">
+ <a href="../func/init.html#cdCreateCanvas"><strong>cdCreateCanvas</strong></a>(CD_GL,
+ Data)</font>, after which other functions in the CD library can be called as usual. The <font face="Courier">Data</font> parameter string has the following format:</p>
+
+ <pre><em>&quot;width<strong>x</strong>height [resolution]&quot;</em> in C &quot;<em><strong><tt>%dx%d %g&quot;</tt></strong></em></pre>
+
+ <p>It must include the initial canvas' dimensions.<font face="Courier"> Width</font> and <font face="Courier">height</font>
+ are provided in pixels (note the lowercase &quot;x&quot; between them). The
+ resolution is optional, its default value is &quot;3.78 pixels/mm&quot; (96 DPI).</p>
+
+
+
+ <p>To use this driver, the application must be linked with the &quot;<strong>cdgl</strong>&quot;,
+ the ftgl library
+ and the OpenGL library. The FTGL library is dependent also on the GLU
+ library.</p>
+ <p>In Lua, it is necessary to call function <font face="Courier"> <strong>cdluagl_open() </strong> </font>after a call
+ to function <strong><font face="Courier">cdlua_open()</font></strong>, apart from linkediting with the &quot;<strong><font face="Courier">cdluagl</font></strong>&quot;
+ library. This is not necessary if you do require&quot;cdluagl&quot;.&nbsp;</p>
