By default, the framebuffer that is used for rendering is the -one belonging to the game window, but custom framebuffers can be used -as well. A common use-case for custom framebuffers is applying -post-processing effects: The entire scene is rendered to a -framebuffer, and then the contents of that framebuffer are applied to -a post-processing shader and rendered to the game window. The -post-processing shader could do any number of things: scaling, -antialiasing, motion blur, etc. -</p> -<dl> -<dt id="index-make_002dframebuffer">Procedure: <strong>make-framebuffer</strong> <em>width height [#:min-filter <code>linear</code>] [#:mag-filter <code>linear</code>] [#:wrap-s <code>repeat</code>] [#:wrap-t <code>repeat</code>]</em></dt> -<dd> -<p>Create a new framebuffer that is <var>width</var> pixels wide and <var>height</var> pixels high. -</p> -<p><var>min-filter</var> and <var>mag-filter</var> determine the scaling algorithm -applied to the framebuffer when rendering.
