<P>
<p>The <a href="QGLFramebufferObject.html#QGLFramebufferObject(int, int, int)"><tt>QGLFramebufferObject</tt></a> class encapsulates an OpenGL framebuffer object.</p>
<p>The <a href="QGLFramebufferObject.html#QGLFramebufferObject(int, int, int)"><tt>QGLFramebufferObject</tt></a> class encapsulates an OpenGL framebuffer object, defined by the <tt>GL_EXT_framebuffer_object</tt> extension. In addition it provides a rendering surface that can be painted on with a <a href="%2E%2E/gui/QPainter.html"><tt>QPainter</tt></a>, rendered to using native GL calls, or both. This surface can be bound and used as a regular texture in your own GL drawing code. By default, the <a href="QGLFramebufferObject.html#QGLFramebufferObject(int, int, int)"><tt>QGLFramebufferObject</tt></a> class generates a 2D GL texture (using the <tt>GL_TEXTURE_2D</tt> target), which is used as the internal rendering target.</p>
<p><b>It is important to have a current GL context when creating a <a href="QGLFramebufferObject.html#QGLFramebufferObject(int, int, int)"><tt>QGLFramebufferObject</tt></a>, otherwise initialization will fail.</b></p>
<p>OpenGL framebuffer objects and pbuffers (see <a href="QGLPixelBuffer.html">QGLPixelBuffer</a>) can both be used to render to offscreen surfaces, but there are a number of advantages with using framebuffer objects instead of pbuffers:</p>
<ol type="1">
<li>A framebuffer object does not require a separate rendering context, so no context switching will occur when switching rendering targets. There is an overhead involved in switching targets, but in general it is cheaper than a context switch to a pbuffer.</li>
<li>Rendering to dynamic textures (i.e&#x2e; render-to-texture functionality) works on all platforms. No need to do explicit copy calls from a render buffer into a texture, as was necessary on systems that did not support the <tt>render_texture</tt> extension.</li>
<li>It is possible to attach several rendering buffers (or texture objects) to the same framebuffer object, and render to all of them without doing a context switch.</li>
<li>The OpenGL framebuffer extension is a pure GL extension with no system dependant WGL, AGL or GLX parts. This makes using framebuffer objects more portable.</li>
</ol>
<p>Note that <a href="%2E%2E/gui/QPainter.html"><tt>QPainter</tt></a> antialiasing of drawing primitives will not work when using a <a href="QGLFramebufferObject.html#QGLFramebufferObject(int, int, int)"><tt>QGLFramebufferObject</tt></a> as a paintdevice. This is because sample buffers, which are needed for antialiasing, are not yet supported in application-defined framebuffer objects. However, an extension to solve this has already been approved by the OpenGL ARB (<tt>GL_EXT_framebuffer_multisample</tt>), and will most likely be available in the near future.</p>
