Framebuffer object
open-in-new
<p>The frame buffer object architecture (FBO) is an extension to <a href="/facts/OpenGL/xQoMWePr">OpenGL</a> for doing flexible off-screen rendering, including rendering to a <a href="/facts/Texture_(computer_graphics)/9gDTsuXN">texture</a>. By capturing images that would normally be drawn to the screen, it can be used to implement a large variety of image filters, and post-processing effects. The FBO is analogous to the render targets model in <a href="/facts/DirectX/jyy75wVN">DirectX</a>. It is used in OpenGL for its efficiency and ease of use. The use of FBOs doesn't suffer from the overhead associated with OpenGL drawing context switching, and has largely superseded the <a href="/facts/Pbuffer/YLAPCLNF">pbuffer</a> and other methods involving context switches. </p>
