Can you send me your program so that I can try it here?

Hello, I'm new to using Mesa and I have run into the
following problem. The colors are not clamping [0,1]. 

In my program the fog is pure green. no other
components.On accelerated Ogl as my object moves away,
the color gets greener until its fully green. wheras
using the same code linked to mesa, it becomes white
and then kinda pinkish and so on... this is happening
in both 16 and 32 bit modes and I'm running it on
windows.

please help.
Thanks a lot in advance.

If you're using Linux you may want to look into  "Programming Linux 
Games" by Loki Software, Inc. with John R. Hall.  ISBN: 1-886411-49-2.   
 Although this book covers a number of topics you may not be interested 
in, it does cover the OpenAL library in enough detail to be practical.   
Examples are included.

The OpenAL website has (had?) some example programs - but this
isn't really an appropriate question for the Mesa list.  OpenAL
has absolutely nothing to do with OpenGL apart from the first
four and last letters of it's name.

Try:

   www.openal.org

Hello,

I writing a small OpenGl application and would like to
add sound files to it?
I've heard about OpenAl.
Maybe you now some examples of sound usage with
OpenAl or any othe free library?

thank you in advance,

Well, I use 'vi'  :-)

I'm told (by people I trust) that Kdevelop is good.

I don't think any of them do that.  There are real
problems with decent free 3D modellers for Linux.
Hopefully when Blender goes OpenSource (as it's
rumored to be doing), we'll have at least one
reasonable choice.

Thanks you very much for the request. I have removed de Mesa 4.0.3
library, and yes, now I have acceleration support with the XFree DRI
driver, but I had need to do some changes to my glide3 library
configuration:

RedHat 7.3 install a common Glide package for the Voodoo3, 4 and 5
graphics cards, and the default setup for this package is for the
Voodoo5. For this reason, a Voodoo3 will not have acceleration support
with X11 DRI driver. The fix to this problem is very easy. I only have
to change a symbolic link to the correct glide3 library. 

It's all. Greetings.

For the Voodoo3 you'll want to use the DRI driver, not the stand-alone
Mesa/Glide driver.  Stand-alone Mesa knows nothing about the DRI so
by installing it, you're effectively disabling the DRI driver.

Remove Mesa 4.0.3 and libGL.* then re-install your XFree86 RPMS.
I think there's an RPM option to force re-installation.  That should
restore the original libGL library.

Voodoo3 support with RedHat 7.3 should just work out of the box
(though I haven't tested it).

The Xmu library should be linked to the GLUT library.
Try this:

	cd Mesa-4.0.3/lib
	ldd libglut.so

You should see something like this (note libXmu):
         libGLU.so.1 => /usr/lib/libGLU.so.1 (0x40052000)
         libGL.so.1 => /usr/lib/libGL.so.1 (0x400ce000)
         libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x4037f000)
         libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x40454000)
         libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40469000)
         libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x404b5000)
         libm.so.6 => /lib/i686/libm.so.6 (0x404bd000)

Hello,

What freeware IDE environemnt would you recommend
to develop OpenGL for Linux?
And what freeware modeller is most suitable to
export it's objects to C?

Thank you in advance,

Thank you. old-style Makefile
really did the job.
but the new problem appeared:
then trying to test demos I gettin'
error messages:

ttt@kdebian:~/Mesa-4.0.3/demos$ ./bounce
./bounce: error while loading shared libraries:
/usr/lib/libglut.so.3: undefined symbol:
XmuLookupStandardColormap
Press any key to continue...

while demos in /xdemos directory work correctly.
and I have 

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/lib
export  LD_LIBRARY_PATH

records in my system bashrc and home directory .bashrc
file.

No.  Mesa needs a few functions from that library.

I don't know what would cause this problem.

I'd suggest trying the old-style Makefiles:

	cd Mesa-4.0.3
	cp Makefile.X11 Makefile
	make clean
	make linux-x86           (or whatever config)


-Brian

yes. I've tryed

kdebian:# locate libXext.so
/usr/X11R6/lib/libXext.so
/usr/X11R6/lib/libXext.so.6
/usr/X11R6/lib/libXext.so.6.4

and included

--x-libraries=/usr/X11R6/lib/

with ./configure, but the result is the
same.
I have XFree86 4.01 on potato.
Maybe it is possible to switch Xext off?

Try this:
	locate libXext.so

That should tell you where the library is located.  There should be
a configure option to let you specify the directory.

 You have to look at the extension's specification.  These are available
 from http://oss.sgi.com/projects/ogl-sample/registry/; extensions which
 have been accepted into the OpenGL standard are documented in the most
 recent release of it, available from http://www.opengl.org/

 HTH,

Marcelo

Dear Mesa users.

I have a question on the extensions.
How can I find function names, which is related to a extension
such as GL_ARB_texture_env_dot3?

I am trying to implement a 3D texture shader.

Thank you in advance.
