[osg-users] NewSight display, information anyone?
Hi everyone, I was wondering if someone has experience with using OSG or OpenGL with a NewSight display (http://www.newsight.com/3d-products/displays.html)? Or else does anyone have any documentation for using these displays? I don't have such a display in my office yet so I can not yet try the current stereo modes in osg, that's the reason why I am asking this now. Thanks a lot already.

Re: [osg-users] Warnings in VS
With latest svn and a clean cache, setting OSG_USE_AGGRESSIVE_WARNINGS to OFF produces zero warnings for OpenThreads, osg, osgDB, and osgUtil. The rest is still building. This is a good thing!

Re: [osg-users] wldap32.lib / osgdb_curl fix
Yes, it is odd that my version of VS 2005 doesn't install this by default, but apparently everyone else's VS 2005 does.

I can, but I would think you'd prefer to "offload" that tedious task to some other developers (me in this case) since it can be pretty time consuming... I suggest you let me have a bash at fixing them (at least the most obvious of them, which may well be 95% of them) and then I'll send you the others.

Re: [osg-users] Help! A simple problem~~ Driving me crazy
Hi Yingpeng,
The OSG by default computes the near/far planes on the fly overriding
the values set by the projection matrix, this default behaviour
ensures that a wide range of models are loadable in OSG application
without application programmers having to check the size of the model
and manual setting of the near/far to this range.
If you want to explictly control the near/far planes then simply
switch off the compute near/far via:
viewer.getCamera()->setComputeNearFearMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
Robert.

Re: [osg-users] Warning level
J-S, /W4 is generally sufficient. I run all of my projects at warning level 4, and effectively treat warnings as errors for my purposes. I don't enable /WX on the off chance that I get some crazy warning that I can't suppress and isn't meaningful in my application. I know of several such warnings for the linker (which are VERY annoying, and generally only deal with debug info), though I haven't actually come across any in the compiler. I suppose some of the warnings that are suppressed by default could be individually turned on if they were deemed beneficial, but this would require sorting through the list of default-off warnings and deciding whether we want each one on or off. My standard Win32 compile options, as relating to warnings, are the following: /D "_CRT_SECURE_NO_DEPRECATE" /D "_CRT_SECURE_NO_WARNINGS" /D "_CRT_NONSTDC_NO_DEPRECATE" /W4 So, set at warning level 4 with all of the crazy warnings about MS replacement of standard-C/C++ functions supressed.

Re: [osg-users] Warning level
Hi Robert,
Could VS users please do an svn update and see how the build now fares?
I'll do this in a few minutes.
I've just done a full build in both debug and release, with /W4 only and
OSG_USE_AGGRESSIVE_WARNINGS set to ON. All built fine. There are a bunch
of warnings I could fix, but these will wait, I've got to get back on
top of things with the "real work" first :-)
So here's the changed CMakeLists.txt file with /Wall removed, and /W3
changed to /W4 when OSG_USE_AGGRESSIVE_WARNINGS is ON.
By the way, a bunch of the warnings I get are of the "unreferenced
formal parameter" variety. I thought GCC flagged those? For example:
void apply(osg::Node& node) { return; }
where 'node' is not used, for which the solution is of course:
void apply(osg::Node&) { return; }
Also, there are some warnings I don't think I can fix, like for example
on this line:
OSGANIMATION_ASSERT(0 && "invalid input data");
I get "conditional expression is constant" (because of the string of
course). But when I get a chance, I'll go through it and try to fix most
warnings.
Thanks,
J-S

Re: [osg-users] Warning level
Hello Matthew, /Wall enables *ALL* warnings, including those automatically supressed by VS under any other circumstances. /W1 through /W4 set the warning level; /Wall goes far beyond /W4 by enabling normally disabled warnings. I'm not sure if /Wall ignores #pragma warning supression as well, as I have never used it in any real situation. If it does ignore the #pragmas, then you would be getting even *more* warnings, on top of all of those that would otherwise be supressed by VS internally. OK, thanks a lot for the information. So I think we can deduce that /Wall is pretty much useless for any real situation. Next question, is /W4 sufficient to use with OSG_USE_AGGRESSIVE_WARNINGS, or is there some other option we could use in addition to get even more informative warnings (without going as far as /Wall...)?

[osg-users] create window from a thread on windows
Hi, I create a an osgViewer from a thread not the main, and i dont have key sent to my windows when i hit the keyboard. Is there something special on windows to have this work ? I know there is a difference between console application and window application is it something related ? In my case i let the console application because the window is not created at the beginning but later from another thread. A side effect is that the window display "not responding" but the opengl inside window is displayed and refresh. Any clue or suggest will be welcome.

Re: [osg-users] Warning level
Hi Robert, I think option A is better, since then people who want to use more aggressive warnings (and can accept the consequences) still have that option. Option B simply makes the flag the same whether OSG_USE_AGGRESSIVE_WARNINGS is ON or OFF, so the option has no use on Windows... Is -Wall /W3 the default then? This is what is now used when enabling OSG_USE_AGGRESSIVE_WARNINGS. No, when OSG_USE_AGGRESSIVE_WARNINGS is OFF then only /W3 is enabled, /Wall is not. I just checked, and it seems /Wall is the option causing the noise. Setting OSG_AGGRESSIVE_WARNING_FLAGS to "/Wall /W3" (as you had done) still blurted out a great number of warnings in the standard C++ headers / headers provided by the compiler. I tried setting OSG_AGGRESSIVE_WARNING_FLAGS to /W4 only (no /Wall) and I got a few warnings which I didn't get before with only /W3, and no warnings in the standard headers: 1>-- Build started: Project: OpenThreads, Configuration: Debug Win32 -- 1>Compiling... 1>Atomic.cpp 1>..\..\..\..\src\OpenThreads\common\Atomic.cpp(133) : warning C4239: nonstandard extension used : 'static_cast' : conversion from 'volatile const long' to 'volatile const unsigned int &' 1>A non-const reference may only be bound to an lvalue 1>Version.cpp 1>Win32ThreadBarrier.cpp 1>Win32Thread.cpp 1>..\..\..\..\src\OpenThreads\win32\Win32Thread.cpp(136) : warning C4189: 'pd' : local variable is initialized but not referenced 1>Win32Mutex.cpp 1>WIN32Condition.cpp 1>Generating Code... 1>c:\dev\openscenegraph-svn\openscenegraph\src\openthreads\win32\win32thread.cpp(440) : warning C4702: unreachable code 1>Compiling manifest to resources... 1>Linking... 1>LINK : C:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\build\bin\RelWithDebInfo\..\..\bin\ot11-OpenThreads.dll not found or not built by the last incremental link; performing full link 1> Creating library C:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\build\lib\RelWithDebInfo\..\OpenThreads.lib and object C:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\build\lib\RelWithDebInfo\..\OpenThreads.exp 1>Embedding manifest... 1>Build log was saved at "file://c:\Dev\OpenSceneGraph-SVN\OpenSceneGraph\build\src\OpenThreads\win32\OpenThreads.dir\RelWithDebInfo\BuildLog.htm" 1>OpenThreads - 0 error(s), 3 warning(s) == Build: 1 succeeded, 0 failed, 1 up-to-date, 0 skipped == So I suggest setting OSG_AGGRESSIVE_WARNING_FLAGS to /W4. The effect will be that when OSG_USE_AGGRESSIVE_WARNINGS is OFF, then /W3 is used, and when it's on, /W4 will be used. The default of OSG_USE_AGGRESSIVE_WARNINGS being ON will mean we'll have a few warnings to fix to get a clean bill of health I imagine. Could someone more knowledgeable than me in these things (Matthew Fuesz for example?) comment? Are there other flags we could use to be even more aggressive on warnings, but still not get warnings in the standard headers which we have no control over?

Re: [osg-users] Warning level
Hi Robert, I agree with your rationale over warnings etc. In this instance the Windows build is now broken due to aggressive warnings Well, it wasn't really broken, just building *really* slowly due to thousands of warnings being printed (probably hundreds for each source file, since they all include mostly the same headers). Clearly this big step backwards and isn't viable, so we'll need to pull back on the warnings levels under Windows, the suggestion of /W3 seems a reasonable compromise so I've just change the VS aggressive warning CmakeLists.txt script path to use this. An svn update will get this change. Just to be sure, this is a Windows-only path right? To be clear: A) Did you set OSG_USE_AGGRESSIVE_WARNINGS to OFF on Windows but ON everywhere else? B) Or did you set the flag to /W3 when OSG_USE_AGGRESSIVE_WARNINGS is ON? I think option A is better, since then people who want to use more aggressive warnings (and can accept the consequences) still have that option. Option B simply makes the flag the same whether OSG_USE_AGGRESSIVE_WARNINGS is ON or OFF, so the option has no use on Windows... Could VS users please do an svn update and see how the build now fares? I'll do this in a few minutes.

Hi Paul, After installing the operating system, I installed Visual Studio 2005 Standard Edition, and accepted all the defaults. When building OSG, everything built fine except for osgdb_curl, which could not find wldap32.lib. This file was not installed as part of the Visual Studio 2005 installation.

Re: [osg-users] Warnings in VS
Hi Paul, Anyone else seeing this issue? Yes, see the thread "Warning level" I started over the holidays. :-) The default behavior appears to be /W4, and there doesn't appear to be a CMake switch to change it. OSG_DISABLE_MSVC_WARNINGS is set to OFF, but this variable is ignore in the CMake scripts, as near as I can tell. OSG_USE_AGGRESSIVE_WARNINGS defaults to ON, but setting it to OFF has no effect. It has an effect only if you set it to OFF before clicking Configure the first time. After that, it seems to be cached and changing the value doesn't change anything, you need to delete your cache and run CMake again.

Re: [osg-users] osgAL now has a CMake script
Hi Sukender,
I have tested osgAL on Arch Linux 0.72 and GCC 4.0.3. It also works after
some changes. :-)
First, I think there should be an important definition for openalpp. Modify
the CMakeLists.txt in src/openalpp:
add_definitions(
-DOPENALPP_EXPORTS
-DOPENAL_VERSION=2007
#-D_USRDLL
)
Otherwise I got lots of compile errors because of missing the OpenAL
version. The OPENAL_VERSION macro had been defined in the configure.in before
and maybe it could be made as an CMake option to users from now on.
And I would suggest do a few changes to the FindOGG.cmake, especially the
FIND_LIBRARY(OGG_LIBRARY ...) macro, to make it work in Linux. See
attachment for details.
Cheers,
Wang Rui

Re: [osg-users] osgAL now has a CMake script
Hi Wang
Thank you very much.
Dependencies are normally in different directories. But if you put all of them
together, then you may change inlude and lib dirs variables in CMake... I have
to chek it.
And thanks for the "INCLUDE_WITH_VARIABLES" modification. I'll write it and
commit soon (this afternoon for me ~= 12:30 PM GMT).

HI ?? Gordon's reply is perfectly reasonable. It is bad etiquette to keep posting on the same topic using different threads. You are misusing this mailing list and the abusing the goodwill of those who use it. It is perfectly reasonable to raise problems that you encounter and seek assistance in resolving it, but you should reply to the existing threads on this topic if it has already been discussed. This makes it much easier for others to follow the topic. Trying to follow broken topics like what your posts instigate is a nightmare. If you want assistance make it easy to assist you otherwise others will not be able help you. Robert.

Re: [osg-users] osgAL now has a CMake script
Hi Sukender,
I have just built osgAL on my Windows XP and VS9. It works for me after some
modifications. I had put the ogg, vorbis and openal headers into 3 different
directories. The structure is:
3rdParty -> include -> AL, ogg, vorbis
-> lib -> ...
And there were building errors while using the CMake 2.6 system to generate
Makefiles, simply because some projects couldn't find the vorbis header
"vorbis/vorbisfile.h". I modified the CMakeLists.txt of src/osgAL and all
example directories and solved them.
For example, in examples/osgal/CMakeLists.txt, change the line
INCLUDE_WITH_VARIABLES( ${EXE_NAME} OPENAL ALUT)
into
INCLUDE_WITH_VARIABLES( ${EXE_NAME} OPENAL ALUT VORBIS )
Hope that helps. Best wishes,
Wang Rui

Hi Michael, Using libzip would be reasonable thing to do.

The osg-users list is free from spam because I have enabled the policy of discarding all posts from non subscribed posters, originally I did try to use mailman's filter of spam but it ended up being a big drain on my time and life force keeping on top of it. There are downsides to this policy in that posts from genuine posters who aren't subscribed just go into an email black hole, this is price we've had to pay for my sanity. -- On the topic of net searchings, and visibility having the forum under forum.openscenegraph.org would probably be better.

Re: [osg-users] Warning level
Hi All, I turned on the aggressive warnings by default following my warnings purge. I can disable this, but doing so would allow users to post code with warnings without realising it, then I or others have to go and guess at what the appropriate warning fix would be which is the danger of introducing bugs can come in. Fixing warnings as you develop code highly preferable as it allows the person with the most knowledge about the code to avoid ambiguities as they write it, learning how to write cleaner code in the process. My hesitancy over upping warning levels is that most warnings don't directly map to bugs, and changing code to avoid warnings can involve jumping through some rather odd coding strategies where the code actually becomes less readable, less maintainable and more prone to introducing bugs. If you don't really understand what the warning relates to, and what the code that producing the warning is trying to do then there is a real risk of unintentional breaking once working code. "If it ain't broke don't fix it" is a good phrase to keep in mind when thinking about fixing warnings. In my role as maintainer I get to see the full life cycle of code, including warning fixes that fix bugs, and ones that introduce bugs, I include my own attempts at warning fixes as well as others. The most experienced engineers tend to have a better hit rate with fixing more bugs than introducing new ones as they will be better at reading the actual intention of the algorithm and it's caveats, but I've haven't yet seen any engineer make no mistakes... One can only strive for perfection, no one can achieve it. In this instance the Windows build is now broken due to aggressive warnings so the double edge sword of warnings has raised it's ugly head in a different aspect, the code was actually in pretty good shape but now won't compile at all for some without changing the build system. Clearly this big step backwards and isn't viable, so we'll need to pull back on the warnings levels under Windows, the suggestion of /W3 seems a reasonable compromise so I've just change the VS aggressive warning CmakeLists.txt script path to use this. An svn update will get this change. Could VS users please do an svn update and see how the build now fares?

Re: [osg-users] What is the best way to record a game scene?
Hi Rick, The OSG's animations are typically based on the FrameStamp::getSimulationTime() which by default is the FrameStamp::getReferenceTime() which is set by the viewer on each new frame. You can specify your own simulation time by passing the time into the viewer.frame(simulationTime) call. This will work for types of animation that are directly computable at any time point, but objects that compute their position iteratively like particle systems it won't work. Robert.

Re: [osg-users] map/set iterator not dereferencable
Hi Malcom,
There really isn't enough info from your post about what your wider
application code and how it relates to this callback and the data is
referencing to guess at what might be wrong. The only thing hint
that code provides is that you're using a global to pass in the data
to modify, this is not a recommended programming practice and may well
be the cause of your problems.
Robert.

Re: [osg-users] Both orthographic and perspective projections for the same camera
Hi Guher(?),
You can nest Camera's to override the project and modelview matrices,
or as your follow up post mentionds you can use osg::Projection that
just overrides the projection matrix.

Re: [osg-users] prerender camera's color mask
Hi David, There really isn't enough info about your scene graph setup to say what might be amiss. My best guess is to check that your texture have an alpha channel. Robert.

[osg-users] Happy New Year!
Hi All, I'm now back from my festive holiday, so will catch up with submissions and user discussions. Once I'm back ontop of my inbox I'll get back to putting down some of my thoughts on the year gone by and the year(s) ahead, something I had intended to do before Christmas but... was just too busy with urgent work and festive preparations ;-) Best wishes for peace and prosperity to all for this new year, Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
