| 12 | <H1>1. Introduction</H1> |
| 13 | |
| 14 | <p> |
| 15 | The GLFBDev driver interface allows one to do OpenGL rendering into a |
| 16 | framebuffer managed with the Linux's fbdev interface. |
| 17 | </p> |
| 18 | |
| 19 | <p> |
| 20 | Basically, the programmer uses the fbdev functions to initialize the |
| 21 | graphics hardware and setup the framebuffer. |
| 22 | Then, using a calls to Mesa's glFBDev API functions, one can render |
| 23 | into the framebuffer with the OpenGL API functions. |
| 24 | </p> |
| 25 | |
| 26 | <p> |
| 27 | Note, only software rendering is supported; there is no hardware |
| 28 | acceleration. |
| 29 | </p> |
| 30 | |
| 31 | |
| 32 | <p> |
| 33 | The GL/glfbdev.h header file defines the glFBDev interface. |
| 34 | </p> |
| 35 | |
| 36 | <p> |
| 37 | The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface. |

| 72 | <h1>4. Running glFBDev programs</h1> |
| 73 | |
| 74 | <p> |
| 75 | First, you need to have a working fbdev environment. |
| 76 | See the |
| 77 | <a href="http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html" target="_parent"> |
| 78 | Framebuffer Howto</a> for information. |

| 82 | Programs must be run with root permission. |
