I have just started reading _The OpenGL Superbible, 4th ed._
but there is absolutely no mention of *BSD anywhere in the book.
Is there an overview of OpenGL, GLUT, etc. as used in OpenBSD?
apropos OpenGL has a little info, but not much.

Thanks,
Dave Feustel

You can use the Mesa implementation of OpenGL (http://www.mesa3d.org/)
which is bundled in the X.org file sets.
GLUT is available in the ports tree.

Mesa is mentioned in the Super Bible (SB). My impression is that
one uses mesa when there is no hardware driver support for OpenGL
and that the version of OpenGL/Mesa supported is determined by the
video driver support. I.e. upgrading OpenGL (eg from 2.0 to 2.1)
requires upgrading the video driver. Is that correct?

I have installed the glut package and am now building and running the OpenGL program
examples in the SuperBible. Would these programs run faster with open source drivers
for ATI video cards?

Thanks.

afaik, opensource ATI video card drivers are much limited in
hardware 3D supports. only some very old display cards are fully
3D accelerated, such as those with R200 cores...

it seems that ATI cards above Radeon 9xxx are only 2D
accelerated...

I've built and run most of the example programs in the SuperBible. I now need GLSL to
run programs. Is GLSL available for OpenBSD?

Are PBO extensions available for OpenBSD?

Also, it would be nice to support OpenGL 1.4.

/home/daf}glxinfo | grep -i version
server glx version string: 1.2
client glx version string: 1.4
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)
glu version: 1.3

Any chance of getting the OpenEXR package updated to include the IlmThread library?

the current version of Xorg under OpenBSD is still 6.9.0 ?
Xorg 6.9.0 still uses Mesa 6.x. while Xorg 7.3 now uses Mesa 7.x
