  13 The GLFBDev driver interface allows one to do OpenGL rendering into a
  14 framebuffer managed with the Linux's fbdev interface.
  15 </p>
  16
  17 <p>
  18 Basically, the programmer uses the fbdev functions to initialize the
  19 graphics hardware and setup the framebuffer.
  20 Then, using a calls to Mesa's glFBDev API functions, one can render
  21 into the framebuffer with the OpenGL API functions.
  22 </p>
  23
  24 <p>
  25 Note, only software rendering is supported; there is no hardware
  26 acceleration.

  31 The GL/glfbdev.h header file defines the glFBDev interface.
  32 </p>
  33
  34 <p>
  35 The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface.

  47 <p>
  48 To compile Mesa with support for the glFBDev interface:
  49 <pre>
  50    XXX todo
  51 </pre>
  52
  53 <p>
  54 When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo.

  73 First, you need to have a working fbdev environment.
  74 See the
  75 <a href="http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html" target="_parent">
  76 Framebuffer Howto</a> for information.
