<p>The <a href="QGLPixelBuffer.html#QGLPixelBuffer(int, int, com.trolltech.qt.opengl.QGLFormat, com.trolltech.qt.opengl.QGLWidget)"><tt>QGLPixelBuffer</tt></a> class encapsulates an OpenGL pbuffer.</p>
<p>Rendering into a pbuffer is normally done using full hardware acceleration. This can be significantly faster than rendering into a <a href="%2E%2E/gui/QPixmap.html"><tt>QPixmap</tt></a>.</p>
<p>There are three approaches to using this class:</p>
<ol type="1">
<li><b>We can draw into the pbuffer and convert it to a <a href="%2E%2E/gui/QImage.html"><tt>QImage</tt></a> using <a href="QGLPixelBuffer.html#toImage()"><tt>toImage</tt></a>.</b> This is normally much faster than calling QGLWidget::renderPixmap().</li>
<li><b>We can draw into the pbuffer and copy the contents into an OpenGL texture using <a href="QGLPixelBuffer.html#updateDynamicTexture(int)"><tt>updateDynamicTexture</tt></a>.</b> This allows us to create dynamic textures and works on all systems with pbuffer support.</li>
<li><b>On systems that support it, we can bind the pbuffer to an OpenGL texture.</b> The texture is then updated automatically when the pbuffer contents change, eliminating the need for additional copy operations. This is supported only on Windows and Mac OS X systems that provide the <tt>render_texture</tt> extension.</li>
</ol>
<p>Pbuffers are provided by the OpenGL <tt>pbuffer</tt> extension; call hasOpenGLPbuffer() to find out if the system provides pbuffers.</p>
