Mesa and photon

Hi everyone,

I had no answer to my previous post, I try again.

I’ve read some docs about Mesa. It seems to need X-windows (or any
equivalent…).

I’ve read somewhere that mesa is available for QNX6.? (I can’t remenber)!

Is this a port of Mesa for photon, or does it need the Xfree thing to work?

I wish to use openGL for fast graphics, on both OSes Win and Neutrino. But I
have no room to embed Xfree!

Please help! :astonished:)

Thanks,

Didier.

Hi Didier,

I will be able to tell you if it is available in January. There is a
limitation to it though in that you have to use a Voodoo Card with glide.

Hi Didier,

If you look at http://developers.qnx.com/NewStuff/Software/
there is photon3d-6.1-x86-qnx.qpr this package contains the info your
looking for, but as I mentioned before it only supports the Voodoo 3 and
Banshee chipssets for hardware acceleration.

GUI Group,

Are the glx commands missing from the photon3d qpr? While they
are defined in GL/glx.h, I can’t seem to find them in the GL libraries.
Or are there/will there be substitute commands for use with photon?

Specifically, I’m missing the following:

unknown symbol: glXQueryServerString
unknown symbol: glXUseXFont
unknown symbol: glXQueryExtension
unknown symbol: glXMakeCurrent
unknown symbol: glXChooseVisual
unknown symbol: glXDestroyContext
unknown symbol: glXSwapBuffers
unknown symbol: glXCreateContext
unknown symbol: glXGetConfig

and they don’t seem to be in libGL or libGLU (using objdump -x)

Thanks,

-Arthur

Hi Arthur,

I checked with the developers and the GLX has not been ported to photon.
GLX is for X only. Some of the functionality of GLX is in our
PdOpenGLContext stuff but not all of it (look at the examples).

Hope this helps

Brenda

Brenda,

Thanks for the info. I’m really hoping use Togl (an opengl wrapper package
for tcl/tk http://togl.sourceforge.net) under qnx 6, but it contains a few
of the
dreaded GLX calls.

It seems like it would be pretty simple to port, but I don’t know the photon
api and the mesa port seems fairly fragile at this stage. Do you know if
any
developers have ported Togl or might be willing to take a look at it?

Thanks,

-Arthur

Hi Arthur

No the Togl hasn’t been ported and unfortunately there are no plans at
this time to do it.
