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> <h1>2. Compilation</h1> <p> To compile Mesa with support for the glFBDev interface: <pre> XXX todo </pre> <p> When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo. </p> </p> xxx todo </p> <h1>3. Compiling and linking glFBDev programs</h1> <p> xxx todo </p> <h1>4. Running glFBDev programs</h1> <p> First, you need to have a working fbdev environment. See the <a href="http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html" target="_parent"> Framebuffer Howto</a> for information. </p> <p> Programs must be run with root permission. </p> </p> </body> </html>
