Line 1:
The '''frame buffer object''' architecture (FBO) is an extension to [[OpenGL]] for doing flexible off-screen rendering, including rendering to a [[texture (computer graphics)|texture]]. 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 [[DirectX]]. 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 The use of FBOs doesn't suffer from the overhead associated with OpenGL drawing context switching, and has largely superseded the [[pbuffer]] and other methods involving context switches.
