The FBO has two main uses: The post-processing of rendered images and composition between different scenes.

Some examples are:

# The rendered image is captured and subjected to [[PixelFragment Shaders]] or other manipulations. This allows for many of today's popular computer graphics effects to be carried out, including the addition of a blurring or bloom effect.

# Can be used to create views of other scenes, for example: a TV in a house. A scene can be rendered through an FBO to a texture, then that texture can be applied to the surface of a TV. This is sometimes called "Render to Texture" or RTT.
