Introduction</H1> - -<p> -The GLFBDev driver interface allows one to do OpenGL rendering into a -framebuffer managed with the Linux's fbdev interface. -</p> - -<p> -Basically, the programmer uses the fbdev functions to initialize the -graphics hardware and setup the framebuffer. -Then, using a calls to Mesa's glFBDev API functions, one can render -into the framebuffer with the OpenGL API functions. -</p> - -<p> -Note, only software rendering is supported; there is no hardware -acceleration. -</p> - - -<p> -The GL/glfbdev.h header file defines the glFBDev interface. -</p> - -<p> -The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface. -</p> - - -<p> -For more information about fbdev, see the -<a href="http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html" target="_parent"> -Framebuffer Howto</a> -</p> -<p> -You will need at minimum, a framebuffer device, check /dev/fb0 -</p> - -<h1>2. Compilation</h1> - -<p> -To compile Mesa with support for the glFBDev interface: -<pre> - make realclean - make linux-fbdev -</pre> - -<p> -When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo. -</p> -<h1>3. Permissions</h1> - -<p> -Typically /dev/fb/0 is grouped to the video group. It may be useful to add -your user to the video group so the demos will not have to be run as root. -To use fbdevglut with the prefered tty input, you should add the user to the -tty group as well -<p> - -<h1>4. Using fbdevglut</h1> -Almost all of the programs in the progs directory use glut, and they compile with fbdevglut. - -<p> -To compile the redbook sample programs: -<pre> - cd progs/redbook - make -</pre> -</p> -<p>glut features not supported: -<li>Overlays -<li>Subwindows -<li>Input devices other than Keyboard/Mouse -<li>No support for GLUT_MULTISAMPLE, GLUT_STEREO, or GLUT_LUMINANCE -<li>Cursor and Menu Support will flicker in GLUT_SINGLE mode - -<p>Keyboard input is read by opening /dev/tty and reading keycodes in medium raw mode. -<p>Mouse input is read from env var MOUSE, or /dev/gpmdata and should be in ms3 format. -To forward data in this format to /dev/gpmdata, run gpm with the -Rms3 option. -<p> glutInit allows glut programs to pass parameters to the glut library, currently the -following options are supported for fbdevglut: -<p><li>-geometry widthxheight -- This will force the resolution to be widthxheight instead of autodetecting. -The modes are read from /etc/fb.modes -<p><li>-bpp -- This will force the bitdepth to the one specified -<p><li>-vt -- This allows you to specify the virtual terminal to attach keyboard input to. It is useful to specify when running inside screen. -<p><li>-mousespeed -- A floating point multiplication factor to increase mouse speed -<p><li>-nomouse -- Disable mouse support -<p><li>-nokeyboard -- Disable keyboard support (this will probably break mouse support as well) -<p><li>-stdin -- Use stdin for input instead of attaching to kbd in medium-raw mode. -This will make it impossible to detect keypresses like Shift+Tab, you will also need to specify -gpmmouse for mouse support. This option can be used with a debugger, and it is possible to single step a program with gdb and set the FRAMEBUFFER environment variable to a different framebuffer for display. The program will not be able to handle vt switching on it's own, so it will always display. -<p><li>-gpmmouse -- This will attempt to connect to the /dev/gpmctl socket using liblow -for mouse data. Gpm does not provide this data when in graphics mode, so vt switching -will briefly display text. This mode typically has no initial mouse delay. -<p><li>-- Ignore any additional arguments -<p>Notes: -<p> -1. The mouse pointer flickers in single buffering mode, as it must be rendered in software. Hopefully in the future there will be a way to access hardware cursors in fbdev devices. -</p> -</body> -</html> |
