I had just been accepting that as normal. 100% CPU is not normal at all. Yikes! I think there must be something seriously wrong with my system then. I updated my video drivers to the latest this morning and enabled vsync. Enabling vsync sent my framerate from 1200 fps to 15 fps! Vsync on or off made no difference on the cpu load- I always have 100% utilization on one core. I have a FireGL V7700 with 512 MB of RAM. I'm running the 8.603 drivers on quad core XP Pro machine. My one-and-only monitor is a 24 Dell panel at 1920x1200. I turned vsync back off. With it on, my cow looked like it was being rotated by a stepper motor.

Re: [osg-users] The story continues: osgthirdpersonview crashes on Linux
Last SVN checkout works perfectly! Now I have only to understand why the GCC builtins are not configured on my system. You say I'm forced to define the environment variable CXXFLAGS to -march=i686 before running ccmake . ? It is not possible to define CMAKE_CXX_FLAGS and CMAKE_C_FLAGS inside Cmake?

Re: [osg-users] The story continues: osgthirdpersonview crashes on Linux
Thanks a lot Mathias!
Adding your file, deleting the cache and starting over:
- Confing now has #define _OPENTHREADS_ATOMIC_USE_MUTEX
- But the build fails when compiling Referenced.cpp
/local/OSG/OpenSceneGraph/src/osg/Referenced.cpp:85: error: qualified name does not name a
class before '{' token
gmake[2]: *** [src/osg/CMakeFiles/osg.dir/Referenced.o] Error 1
gmake[2]: *** Waiting for unfinished jobs
gmake[1]: *** [src/osg/CMakeFiles/osg.dir/all] Error 2
gmake: *** [all] Error 2
Seems like _OSG_REFERENCED_USE_ATOMIC_OPERATIONS is not defined.
So I added to Config header the line:
#define _OSG_REFERENCED_USE_ATOMIC_OPERATIONS
And voila', everything works, no more crashes in osgthirdpersonview !
Hope this helps you. Ciao!

configuring capabilities that are not there... Bho?
Ok, the cflags did not reach the compiler command line. Therefore you do not
get atomics. It's beyond my cmake knowledge when which cmake variable is
used.
I usually set CFLAGS and CXXFLAGS in the environment where I run cmake. That
appears to work for me ...
Hmm, I wonder why your previous post tells that none of the OpeThreads Config
variables are defined. At least the MUTEX one should be ...
Can you replace the CheckAtomicOps.cmake file with the one I have attached and
retest please? Note that I am interrested in the fallback path with the
mutex, so please do not change eny cflags or whatever wrt the previous run
that did not work ...
Thanks!
Greetings

Just done a svn co in an empty dir
Can you please start a build from scratch in an empty directory and tell me if
this still does not work?
Done ccmake .
then cmake --debug-trycompile
You may start cmake with --debug-trycompile and provide the output of
builddir/CMakeFiles/CMakeError.log.
Log attached.
As soon as the build finishes, I will report back to you.

Re: [osg-users] osgthirdpersonview crashes on Linux
Ok, I see. You are running in gcc, i386 without any -march= compiler flag. So gcc assumes that you want to compile for a plain old i386 (read this does not even mean an i486). In this case gcc is limited to an instruction set where no such atomic operations are available. In fact you could not even programm a mutex with that i386 instruction set, as well as you could not build any SMP machine using an i386. Ahi Ahi Ahi!! That means that I'm working without this optimization since the beginning? And nevertheless OSG is so fast? I specify in the advanced cmake options: CMAKE_C_FLAGS-march=i486 -mtune=i486 CMAKE_CXX_FLAGS -march=i486 -mtune=i486 Then configure and generate, but the ./include/OpenThreads/Config file continues with everything commented out. Have I missed something? In this case, when we cannot assume any atomic operations. So we need to use the previous mutex based behaviour. But for that, the old mechnisms are still there. You need to ensure that refcounting works in a threadsafe way using either the OSG_THREAD_SAFE_REF_UNREF environment variable or by calling OK, thanks. But for now I want only to contribute with my ignorance :-) to polish this OSG functionality. osg::Referenced::setThreadSafeReferenceCounting(true); before *any* concurrently used osg::Referenced object is created. Alternatively you can uncomment that ENFORCE_THREADSAFE define in src/osg/Referenced.cpp that does change the default behaviour of referenced. As soon as the build finishes, I will report back to you. OK, now crashes in another place, see below. This run has been done before changing march/mtune. Are you running with the environment variable OSG_THREAD_SAFE_REF_UNREF set or unset?

CMakeCache.txt or something specific to that user. No one else has experienced this (except when we moved from the old 3rdParty binaries to Mike's SVN a while ago, which seems to be what happened for this user too) so I don't think it's an issue with the project as a whole. On Windows, when CMake generates the Visual Studio project files, they no longer contain the headers under the Header files folder in the core projects. This doesn't affect the build itself, but it's inconvenient since we're used to having all the sources and headers there. Is there an additional tweak to make to the CMake configs? The build itself seems to be going fine. I'll let you know when it finishes.

developer release:
http://www.openscenegraph.org/projects/osg/wiki/Downloads/DeveloperReleases
* OpenSceneGraph-2.3.10, released on 22nd April 2008.
OpenSceneGraph-2.3.10 is the 2nd release candidate for 2.4. Minor
changes are to NEWS, ChangeLog?, AUTHORS, and a small tweak of
osgTerrain and Win32 build support of libcurl file
source package : OpenSceneGraph-2.3.10.zip
svn tag: svn co
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.3.10
OpenSceneGraph
Changes were all very minor relative to 2.3.9 - suggesting that we are
looking good for the 2.4 release. As ever I'd appreciate any testing
that can be done. As long as no errors are found I'll go ahead and
tag 2.4 stable tomorrow morning.
Thanks in advance,
Robert.

Hi All,
I have just tagged a second 2.4 release candidate - the 2.3.10
developer release:
http://www.openscenegraph.org/projects/osg/wiki/Downloads/DeveloperReleases
* OpenSceneGraph-2.3.10, released on 22nd April 2008.
OpenSceneGraph-2.3.10 is the 2nd release candidate for 2.4. Minor
changes are to NEWS, ChangeLog?, AUTHORS, and a small tweak of
osgTerrain and Win32 build support of libcurl file
source package : OpenSceneGraph-2.3.10.zip
svn tag: svn co
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.3.10
OpenSceneGraph
Changes were all very minor relative to 2.3.9 - suggesting that we are
looking good for the 2.4 release. As ever I'd appreciate any testing
that can be done. As long as no errors are found I'll go ahead and
tag 2.4 stable tomorrow morning.
Thanks in advance,
Robert.

No, methods from TrackballManipulator help you in understanding when you are

I see, but these are not OSG calls, but wxWindows calls.
is it so that one cannot achieve this functionality with OSG, but has to
look outside to a windowing API?

[osg-users] requestContinuousUpdate not called
I have found the reason why requestContinuousUpdate() is not been called in my application (that is based on osgviewerWX example). The osgviewerWX graphics window is derived from osgViewer::GraphicsWindow (class GraphicsWindowWX : public wxGLCanvas, public osgViewer::GraphicsWindow) and here I correctly add the TrackballManipulator and tried to override osgViewer::GraphicsWindow::requestContinuousUpdate() without success. That is because TrackballManipulator calls, when needed, View::requestContinuousUpdate(). So obviously overriding osgViewer::GraphicsWindow::requestContinuousUpdate(), as I was doing, has no effect. Now I created a class derived from osgViewer::Viewer and here I redefine the function and this now works. But this opens a question: which is the goal of adding a virtual requestContinuousUpdate() to osgViewer::GraphicsWindow? Who calls it? Thanks for your help! mario -- Ing.

Re: [osg-users] multiple windows
Nice example, thanks! I had to make some addition to have it compiling under VS 7.1 (and my wx and osg libraries). But beside this, I noticed a strange thing: load spaceship.osg (or fountain.osg) and you notice the motor plumes does not animate. If you make the model rotate, they start animate again. It is something related to your OnIdle optimization. If you comment the if line, then everything animates as usual. Hope it helps. Ciao! mario Thibault Genessay wrote: Hi Emmanuel I have made a sample that demonstrate the integration of the OSG in wxWidgets. It is a simple frame with a wxAUINotebook containing OSG views. You can download source and binaries at http://ips-dil.unil.ch/osg Could you have a look at these and see if this suits your needs ? I am planning to release it as an official sample to OSG+wxWidgets, so I'll need to test it on more systems (not tested on Linux as of today) and more threading models. It uses a modified version of the osgCompositeViewer::Viewer that skips rendering if makeCurrent() returns false. Currently, the composite viewer ignores the return value of makeCurrent().

[osg-users] Clarification on: grabFocus and grabFocusIfPointerInWindow
Is it true that the focus to a Viewer is given only during realize(), set full screen and change resolution operations? From the source seems so. But if I have a GUI that contains various widgets plus a Viewer (that uses a GL canvas widget) and I click on a GUI widget then the focus does not return automatically to the viewer when I move the mouse to be inside the Viewer. That means that I should add a call to grabFocus inside my Viewer OnButtonDown processing or I should add a call to grabFocusIfPointerInWindow to my OnIdle processing. Is this true or I'm overlooking something more obvious? To be concrete: I'm developing a tool with wxWidgets building on top of the provided osgviewerWX example. Thanks for your time! mario -- Ing.
