The Readme's should get you there, but there can be a few glitches, 
depending on how you do the install.  The biggest problem you might face is
that OpenAL is kind of in a state of transition now (OpenAL 1.0 to 1.1 spec,
and a Subversion repository instead of CVS), so some of the less recent 
documentation may be incorrect.

I can probably help you out if you tell me exactly how you downloaded and 
compiled OpenAL and ALUT, and what exactly is going wrong with it.

The work is being done.  It's just a slow process because it's a community-
driven project and the Linux community is still fairly small.

[Rakolta, J. \(NM75\) <Joe...@ho...>]

Thanks Jason,

I'll give that a try.

Do you have any advice for installing OpenAL and ALUT on LINUX?  I
downloaded the source, followed the README's, no dice.

Errors like: can't find AL/alut.h, etc.  I'm not much of a LINUX guy,
but I'm pretty sure I followed the instructions in the README's.

Any help is appreciated.  (OpenAL might be a great thing, but it really
needs work on install procedures etc.)

Thanks for your help,

Joe Rakolta

You must be using a version of Linux that we haven't tested. I believe
R_OK is defined in unistd.h. The fact that it's not #included in the
file leads me to believe that some other header file includes it on RHEL
4, but not the distribution you're using. The fix would be to add a
#else section after the #ifdef _MSC_VER that does #include <unistd.h>.

Make sure you pass --enable-shared to ffmpeg's configure script.
Otherwise, the ffmpeg shared libraries don't get created.

Thanks guys.

I am so impressed with this toolkit.  I discover new capabilities
provided by this tool almost everyday.  To date, I have barely scratched
the surface of the full potential provided by VESS, and I'm very pleased
so far.

I look forward to using this and future releases.

Great job!

That's OK.  Basically, it prints all the extensions supported by your 
video card and driver.  Near the top are the WGL extensions.  WGL is the 
library that links Windows with OpenGL.  In that section, do you see 
anything resembling "WGL_ARB_pbuffer" or "WGL_ARB_pixel_format" ?

If not, that's the cause of your problem with off-screen windows, and 
we'll have to address that.

I don't think you can do it in the order you specified right now, 
although it would be a simple thing to add.  What you can do, though, is 
use your application to create a native window (an X Window or a HWND), 
and then pass that to the constructor for a vsWindow.  VESS will then 
create the OpenGL context inside that window.  We use this technique to 
embed VESS windows inside parent windows created by a GUI library (GTK+, 
in our case).

Can you elaborate on what you need to do?  It may be something we've 
already addressed with a different technique.

I would think it's really dependent on the windowing system being

[Vess-users] sharing windows with vsPipe or vsScreen?

Is it possible to share a Vess window with other applications?

For example, can I use vsPipe or vsScreen to get some kind of openGL

Is there an easy way to create simple overlays using VESS, or using OSG?

I'm anxiously awaiting the next version of VESS - I think this toolkit
is awesome.


You can create a second pane (on top of your main vsPane) and set its
clear mask to 0x0, so it is never cleared.  As long as you add the
overlay pane to the window _after_ the main pane, it should always be on
top.  Then, whatever you draw in the overlay pane will be visible on top
of your main pane.

You might also want to look at the menu library.  There may be some
helpful things in there (depending on what you're trying to do).

VESS 4.1.0 is really close now  :-)

The menu library is very useful for things beyond menus (you could argue
that we should rename it!).

I am ready to go to next step of my SA in driving research. I definately

want to show the speed, maybe only simply show the digital number (speed)

It is greatly appreciated.

Yeah, you'll probably need a later version than that (OSG 0.9.6-2 is slightly
different).  I don't think 0.5.7 had the ParameterBlock, which is why we didn't
stick with it.  You can try the current CVS, but that may actually be too new.  
Give it a try and let me know if you're still having problems.
