Project History
|
|
===============
|
|
|
|
The Mesa project was originally started by Brian Paul. Here's a short
|
|
history of the project.
|
|
|
|
August, 1993: I begin working on Mesa in my spare time. The project has
|
|
no name at that point. I was simply interested in writing a simple 3D
|
|
graphics library that used the then-new OpenGL API. I was partially
|
|
inspired by the *VOGL* library which emulated a subset of IRIS GL. I had
|
|
been programming with IRIS GL since 1991.
|
|
|
|
November 1994: I contact SGI to ask permission to distribute my
|
|
OpenGL-like graphics library on the internet. SGI was generally
|
|
receptive to the idea and after negotiations with SGI's legal
|
|
department, I get permission to release it.
|
|
|
|
February 1995: Mesa 1.0 is released on the internet. I expected that a
|
|
few people would be interested in it, but not thousands. I was soon
|
|
receiving patches, new features and thank-you notes on a daily basis.
|
|
That encouraged me to continue working on Mesa. The name Mesa just
|
|
popped into my head one day. SGI had asked me not to use the terms
|
|
*"Open"* or *"GL"* in the project name and I didn't want to make up a
|
|
new acronym. Later, I heard of the Mesa programming language and the
|
|
Mesa spreadsheet for NeXTStep.
|
|
|
|
In the early days, OpenGL wasn't available on too many systems. It even
|
|
took a while for SGI to support it across their product line. Mesa
|
|
filled a big hole during that time. For a lot of people, Mesa was their
|
|
first introduction to OpenGL. I think SGI recognized that Mesa actually
|
|
helped to promote the OpenGL API, so they didn't feel threatened by the
|
|
project.
|
|
|
|
1995-1996: I continue working on Mesa both during my spare time and
|
|
during my work hours at the Space Science and Engineering Center at the
|
|
University of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me
|
|
do this because Mesa is now being using for the
|
|
`Vis5D <https://www.ssec.wisc.edu/%7Ebillh/vis.html>`__ project.
|
|
|
|
October 1996: Mesa 2.0 is released. It implements the OpenGL 1.1
|
|
specification.
|
|
|
|
March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo
|
|
graphics card via the Glide library. It's the first really popular
|
|
hardware OpenGL implementation for Linux.
|
|
|
|
September 1998: Mesa 3.0 is released. It's the first publicly-available
|
|
implementation of the OpenGL 1.2 API.
|
|
|
|
March 1999: I attend my first OpenGL ARB meeting. I contribute to the
|
|
development of several official OpenGL extensions over the years.
|
|
|
|
September 1999: I'm hired by Precision Insight, Inc. Mesa is a key
|
|
component of 3D hardware acceleration in the new DRI project for
|
|
XFree86. Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon
|
|
follow.
|
|
|
|
October 2001: Mesa 4.0 is released. It implements the OpenGL 1.3
|
|
specification.
|
|
|
|
November 2001: I cofounded Tungsten Graphics, Inc. with Keith Whitwell,
|
|
Jens Owen, David Dawes and Frank LaMonica. Tungsten Graphics was
|
|
acquired by VMware in December 2008.
|
|
|
|
November 2002: Mesa 5.0 is released. It implements the OpenGL 1.4
|
|
specification.
|
|
|
|
January 2003: Mesa 6.0 is released. It implements the OpenGL 1.5
|
|
specification as well as the GL_ARB_vertex_program and
|
|
GL_ARB_fragment_program extensions.
|
|
|
|
June 2007: Mesa 7.0 is released, implementing the OpenGL 2.1
|
|
specification and OpenGL Shading Language.
|
|
|
|
2008: Keith Whitwell and other Tungsten Graphics employees develop
|
|
`Gallium <https://en.wikipedia.org/wiki/Gallium3D>`__ - a new GPU
|
|
abstraction layer. The latest Mesa drivers are based on Gallium and
|
|
other APIs such as OpenVG are implemented on top of Gallium.
|
|
|
|
February 2012: Mesa 8.0 is released, implementing the OpenGL 3.0
|
|
specification and version 1.30 of the OpenGL Shading Language.
|
|
|
|
July 2016: Mesa 12.0 is released, including OpenGL 4.3 support and
|
|
initial support for Vulkan for Intel GPUs. Plus, there's another Gallium
|
|
software driver ("swr") based on LLVM and developed by Intel.
|
|
|
|
Ongoing: Mesa is the OpenGL implementation for devices designed by
|
|
Intel, AMD, NVIDIA, Qualcomm, Broadcom, Vivante, plus the VMware and
|
|
VirGL virtual GPUs. There's also several software-based renderers:
|
|
swrast (the legacy Mesa rasterizer), softpipe (a Gallium reference
|
|
driver) and llvmpipe (LLVM/JIT-based high-speed rasterizer).
|
|
|
|
Work continues on the drivers and core Mesa to implement newer versions
|
|
of the OpenGL, OpenGL ES and Vulkan specifications.
