Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 5 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 6 | The Mesa project began as an open-source implementation of the |
| 7 | `OpenGL <https://www.opengl.org/>`__ specification - a system for |
| 8 | rendering interactive 3D graphics. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 9 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 10 | Over the years the project has grown to implement more graphics APIs, |
| 11 | including `OpenGL ES <https://www.khronos.org/opengles/>`__ (versions 1, |
| 12 | 2, 3), `OpenCL <https://www.khronos.org/opencl/>`__, |
| 13 | `OpenMAX <https://www.khronos.org/openmax/>`__, |
| 14 | `VDPAU <https://en.wikipedia.org/wiki/VDPAU>`__, `VA |
| 15 | API <https://en.wikipedia.org/wiki/Video_Acceleration_API>`__, |
| 16 | `XvMC <https://en.wikipedia.org/wiki/X-Video_Motion_Compensation>`__ and |
| 17 | `Vulkan <https://www.khronos.org/vulkan/>`__. |

Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 19 | A variety of device drivers allows the Mesa libraries to be used in many |
| 20 | different environments ranging from software emulation to complete |
| 21 | hardware acceleration for modern GPUs. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 22 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 23 | Mesa ties into several other open-source projects: the `Direct Rendering |
| 24 | Infrastructure <https://dri.freedesktop.org/>`__ and |
| 25 | `X.org <https://x.org>`__ to provide OpenGL support on Linux, FreeBSD |
| 26 | and other operating systems. |

Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 28 | Project History |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 29 | --------------- |

Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 31 | The Mesa project was originally started by Brian Paul. Here's a short |
| 32 | history of the project. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 33 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 34 | August, 1993: I begin working on Mesa in my spare time. The project has |
| 35 | no name at that point. I was simply interested in writing a simple 3D |
| 36 | graphics library that used the then-new OpenGL API. I was partially |
| 37 | inspired by the *VOGL* library which emulated a subset of IRIS GL. I had |
| 38 | been programming with IRIS GL since 1991. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 39 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 40 | November 1994: I contact SGI to ask permission to distribute my |
| 41 | OpenGL-like graphics library on the internet. SGI was generally |
| 42 | receptive to the idea and after negotiations with SGI's legal |
| 43 | department, I get permission to release it. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 44 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 45 | February 1995: Mesa 1.0 is released on the internet. I expected that a |
| 46 | few people would be interested in it, but not thousands. I was soon |
| 47 | receiving patches, new features and thank-you notes on a daily basis. |
| 48 | That encouraged me to continue working on Mesa. The name Mesa just |
| 49 | popped into my head one day. SGI had asked me not to use the terms |
| 50 | *"Open"* or *"GL"* in the project name and I didn't want to make up a |
| 51 | new acronym. Later, I heard of the Mesa programming language and the |
| 52 | Mesa spreadsheet for NeXTStep. |
Erik Faye-Lund | 4d06683 | 2020-06-12 20:09:42 +0200 | [diff] [blame] | 53 | |
Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 54 | In the early days, OpenGL wasn't available on too many systems. It even |
| 55 | took a while for SGI to support it across their product line. Mesa |
| 56 | filled a big hole during that time. For a lot of people, Mesa was their |
| 57 | first introduction to OpenGL. I think SGI recognized that Mesa actually |
| 58 | helped to promote the OpenGL API, so they didn't feel threatened by the |
| 59 | project. |

Erik Faye-Lund | 0b4f5121 | 2020-01-30 19:27:17 +0100 | [diff] [blame] | 61 | 1995-1996: I continue working on Mesa both during my spare time and |
| 62 | during my work hours at the Space Science and Engineering Center at the |
| 63 | University of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me |
| 64 | do this because Mesa is now being using for the |
| 65 | `Vis5D <https://www.ssec.wisc.edu/%7Ebillh/vis.html>`__ project. |

| 155 | Intel Sandy Bridge and Ivy Bridge is the only driver to support OpenGL |
| 156 | 3.1, many developers across the open-source community contributed |
| 157 | features required for OpenGL 3.1. The primary features added since the |
