Hello All!

Is there an OpenGL library for OS/2 ?

I know there is MESA for Linux and that SGI recently released OpenGL as OSS, but I haven't been able to find an OS/2 port neither on www.sgi.com/software/opengl nor on www.opengl.org.

Mhmm, I do have to following in my BBS:

OGLGOLD.ZIP 4607283 02.10.97 This is the "gold" release of OpenGL 1.1
for OS2. Please forwared any problems to
IBM support or mail a description of the
problem and a testcase to - os2-opengl@utsi.com.

It contains DLLs, LIBs, Headers and Samples.

I haven't found MESA for OS/2. But isn't MGL from Scitech Software a 3D library, too?

Bye,
Vitus

No idea. But if there is an OpenGL library, i'd rather use that since there will be an OS/2 - win32 and Linux version. Moreover, it's about the only way I know to do graphics :-)
Thanks

Hi Francois,

Replying to a message of Francois Thunus to All:

Yes. It comes with the OS/2 Warp Developer's Toolkit 4.0. It should also be on the Warp 4 install CD, somewhere. [It was on the Warp 4 install shipped with Dev Con in 1996.]

I know there is MESA for Linux and that SGI recently released OpenGL
as OSS, but I haven't been able to find an OS/2 port neither on www.sgi.com/software/opengl nor on www.opengl.org.

Look under your nose. ... :-)

IBM OpenGL Gold is a beta version of OpenGL v 1.1. There haven't been any work done on it since its release but like other IBM software it is still available (ftp://ftp.austin.ibm.com/pub/developer/os2/OpenGL). It is recommended, however, that developers target standard OpenGL v 1.0 bundled with OS/2 v 4.x.

I know there is MESA for Linux and that SGI recently released OpenGL

MesaGL has been there for a while (http://www.laser.ru/soft/WarpMesaGL). Another branch of it has made it into Project Odin.

Sincerely yours - Andrew

Further to some other notes here. OpenGL 1.0 is faster than 1.1, so use
it if you don't need the extra features in 1.1. If you have a Pentium
Pro or above CPU, there is a device driver that will improve OpenGL performance. Make sure you use the 1.1 libraries and headers to build
your programs, since if you use the 1.0 libraries on a system with 1.1,
they will fail but if you use the 1.1 libraries on a system with 1.0, it
will work alright. There is an excellent series of articles on
www.edm2.org (might be .com) on OpenGL, just look in the back issues.

There are also Glide libraries (a subset of OpenGL) that are hardware accelerated on the Voodoo I and II if you are interested in that sort of
thing.

I wrote an article on OpenGL in OS/2 on the OS/2 eZine, however their
back issues are currently offline.

other IBM software it is still available AB>(ftp://ftp.austin.ibm.com/pub/developer/os2/OpenGL).

Gold indicates that this was the final release, so I wouldn't call it
Beta. Also, you need to use the headers and libraries from the 1.1
release or else your apps will crash if the user has 1.1 installed on
their system.

Interesting. No, I do not need them. In the meantime, I have found there is also an os/2 port of Mesa. I'll try both and see which one is fastest. Mesa 3.2
supports OpenGL 1.2.

I'll have a look tonite, thanks.

I need to make it as generic as possible, hence the use of OpenGL. Basically what I'm aiming at is a win32-OS/2-Linux.
Mind you, OpenGL is the first thing I thought about, but at this stage nothing is cast in stone yet.
Once the project develops, I might end up with a C program with a Tcl/Tk interface or something even totally different.
Or the whole thing could be cancelled, it is not, unfortunately, the first time
this happens.

Thanks all the same, I'll get the articles for my general education anyway :-)

I've read somewhere that "Gold" designates IBM wide beta versions. The final release of version 1.1 never happened due to rapid collapse of IBM Austin PSP department soon afterwards (in November, 1997).

By the way, if it was the release, they will most likely have it included in Warp 4.5 convenience package(s) but there aren't any plans for OpenGL enhancements in CP#1, as far as I know. Moreover, the Aurora distribution contains the same old rusty OpenGL v 1.0.

Unfortunately, 1.1 breaks all 1.0 applications, which goes against
IBM's modus operandi not to break things with upgrades. Anyone who
needs 1.1 for their app can provide it to their customers.
