| <H1>1. 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> |

| <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. |
