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