AW: [osg-users] Small bug in osg::autotransform
Yes, thanks!
Richard.
Hi Richard,
I have reviewed you changes, and believe that a more lighweight fix
would be to simply reset the _firstTimeToInitEyePoint to true when
setAutoRotatioMode is called:
void setAutoRotateMode(AutoRotateMode mode) { _autoRotateMode =
mode; _firstTimeToInitEyePoint = true; }
This avoids the extra variable. I have checked this fix into SVN.
Does this fix work for you?
Robert.

Hi Richard,
Could you post the modified file so I can review it with a view to

hi
there is a small bug in osg::autotransform. When switching from
osg::AutoTransform::NO_ROTATION to
osg::AutoTransform::ROTATE_TO_SCREEN the new rotation does
not get updated, because the camera position does not change. When
the
camera position changes again, the object is displayed correctly
again. To
fix it just introduce a _rotationDirty flag, which is set when set
when
setAutoRotateMode is called.

Hi, Robert Osfield wrote: Would there be any problem with everybody checking the svn:external OpenThreads out as https? If not I can change it to this. From Martin's email in this thread it seems that some svn clients does not support ssl, so maybe forcing https is not the best option. We could probably move the SVN docs across discussing https only if there isn't any problems. If we cannot just use https, it might help if we just add the instructions for changing the external to https to the docs.

Re: [osg-users] Collision detection
Hi 2007/5/23, The supervisor [EMAIL PROTECTED]: Hello, We're trying to implement a Collision Detection algorithm. Our idea includes building a BB tree. It is a tree of hierarchies where the lowest hierarchy includes bounding boxes of the most basic objects in the scene. The one above includes BBs of pairs of BBs from below, and so on for all upper hierarchies. Note that while constructing the levels above, the pairs of the lower BBs must be chosen carefully, for the wrong choice will lead to a BB far larger than the BB that could be created by choosing BBs which are closer to each other. We've been told that a similar tree is being built in OSG for the purpose of culling. In order to help us build this tree we're searching for the source code of the function which does just that. If you could direct us to the right place in the source we'd be grateful. Alternately, if OSG provides access to his tree of this kind, how can we use it? i don't understand exactly what you need and like doing.

Hi, We are currently using the SVN version of the OpenSceneGraph, and try to use the osgShadow library. Our 3D scene contains a very wide terrain. This downs the osgShadow performance. In some other engines developers could limit the shadow distance, i.e. shadow appears on a frustom from the camera to a given far distance so that shadow performance does not depent on how wide your terrain is. As far as we realize, current shadow technique implementations does not contains such a facility. Is it considered to add such facility to osgShadow library? Also, is it considered to add new shadow techniques such as any kind of perspective shadow techniques? Thanks Aydin Okutanoglu .. DIKKAT !

I have tried using of unref () and unref_nodelete() but I get access violations. Obviously I am misunderstanding how these functions work. Can anyone suggest what I should be doing? You shouldn't call unref() yourself but rather remove the TransformMatrix* from its parent which will call unref() as necessary: Root-removeChild(TransformMatrix1) This will remove TransformMatrix1 from Root, calling TransformMatrix1-unref() which in turn deletes TM1 (since its refcount reaches 0). The destructor calls unref() on all of TM1's children (i.e. Node-unref). You have to take care if you remove both TM1 and TM2 since then the entire Node branch may be deleted unless you keep a ref_ptr to Node.

Hi,
I have got a problem with high CPU usage (100%) with osg in Win64.
To narrow the problem I extended the osgviewer code as follows:
---
...
while( !viewer.done() )
{
end_tick=osg::Timer::instance()-tick();
if(1.0f/60-osg::Timer::instance()-delta_s(start_tick,end_tick)0)OpenThreads::Thread::microSleep(100*1.0f/60-osg::Timer::instance()-delta_s(start_tick,end_tick));
start_tick=osg::Timer::instance()-tick();
// wait for all cull and draw threads to complete.
viewer.sync();
// update the scene by traversing it with the the update visitor
which will
// call all node update callbacks and animations.
viewer.update();
// fire off the cull and draw traversals of the scene.
viewer.frame();
}
...

With Linux this Code works perfectly and limits the framerate to
aproximately 50 fps (Should imho be 60 with this code, but that´s not
that important). Thus CPU usage drops on my machine to around 5% (I
know, this is model-dependant.). Running the same Code with WinXP64,
Visual Studio 2005, causes 100% CPU usage with framerate dropping to
around 50 fps. The machine is fast enough. Graphics board is NVidia, so
the known ATI-Bug does not apply.
Does anyone know if this ist a general Windows problem or only occurs on
Win64 and what causes it? Is there a workaround? I don´t like my
application to eat up all cpu. It is still possible for other Processes
to get CPU-time, but since the viewer seems to grab all free CPU-time,
the fan gets loud and if one tried it on a mobile device the application
consumed much more power than necessary.
Thanks+Best regards

Alternately, if OSG provides access to his tree of this kind, how can we use it? i don't understand exactly what you need and like doing. Do you like to implement yourself a new structurs or do you like to expand the osg internal structurs to support hierarchical collision checks ?

Re: [osg-users] Windows CMake install problem
Hi Serge, I did not see the problem, my install step seem to have installed include\osgViewer correctly Serge Lages wrote: Hi all, I've noticed a problem with the install step of CMake (under Windows). It copies all the include files into the wanted directory except the subdirectory (and all its content) api/ from include/osgViewer/. I include files from it to make some platform dependant things (like getting the HWND with api/Win32/GraphicsWindowWin32), so my projects don't build without it.

Hi Kim, For eye linear texgen you should use a TexGen you should use a TexGenNode to position the TexGen in space as its positional state. Have a look at the examples that use TexGenNode. Robert.

Re: [osg-users] 100% CPU usage Win64
Hi,
is it sufficient to enable vsync in driver settings? If so, I did. Even
if I reduce fps to 10, I get 100% CPU usage. Gfx board in the Windows
machine is a GeForce 7800 GTX, ForceWave version 81.67. Gfx board I
tested with linux is quadro 350m, nvidia-drivers-1.0.9755-r1.

With Linux this Code works perfectly and limits the framerate to
aproximately 50 fps (Should imho be 60 with this code, but that´s not
that important). Thus CPU usage drops on my machine to around 5% (I
know, this is model-dependant.). Running the same Code with WinXP64,
Visual Studio 2005, causes 100% CPU usage with framerate dropping to
around 50 fps. The machine is fast enough. Graphics board is NVidia, so
the known ATI-Bug does not apply.
Does anyone know if this ist a general Windows problem or only occurs on
Win64 and what causes it? Is there a workaround? I don´t like my
application to eat up all cpu. It is still possible for other Processes
to get CPU-time, but since the viewer seems to grab all free CPU-time,
the fan gets loud and if one tried it on a mobile device the application
consumed much more power than necessary.

I've tweak src/osgViewer/CMakeLists.txt (attached), this does the
install of the GraphicsWindow* headers which are appropriate for each
platform. One snag is it doesn't install into
osgViewer/api/Win32/GraphicsWindowWin32 but
osgViewer/GraphicsWindowWin32 so the api/Win32 directory is not
honored. I don't know how to tweak CMake to honour this.

I'm trying to build this release of OSG on linux this time. First thing noticable: the plugins are still built as shared libraries (in mode OPENSCENEGRAPH_DYNAMIC=OFF)... is this normal ?? I've got a question any way: On windows, when I was trying to use .dll for the plugins mixed with static core libraries it didn't work: I'm not un expert, but I guess this could have something to do with static objects in osgDB.lib existing in two places (the application and the plugin) and not being shared as one would expect (please tell me if this explanation is totally wrong :-) ). So I came to the conclusion that everything must be shared or static... is this still true under linux with gcc ??? if it is, then it means we have to build static plugin libs and then to force the compiler to include the needed symbols again... (correct me if I'm wrong but I think that current gcc versions (4.1 at least...) perform function level linking by default). Does anyone know how to retrieve the symbol list from the librairy ? (ie: what is the corresponding command for MS dumpbin.exe ? :-)) still if my previous assumption is true for linux, could someone just tell me what should be changed in order to built static plugin libs in the Cmake files ?

You shouldn't call unref() yourself but rather remove the TransformMatrix* from its parent which will call unref() as necessary: Root-removeChild(TransformMatrix1) This will remove TransformMatrix1 from Root, calling TransformMatrix1-unref() which in turn deletes TM1 (since its refcount reaches 0). The destructor calls unref() on all of TM1's children (i.e. Node-unref).

If you look at the osgViewer CmakeLists.txt, you find that there is a

This variable is not used inside the ModuleInstall file tha gets

in the last line the INSTALL( FILES command only installs
LIB_PUBLIC_HEADERS
It seems that while the selection of the sources (.cpp) files to use is
platform dependentent, the headers are included in the projects for all
the platforms.
If we just add installation steps for the LIB_PRIVATE_HEADERS, we
install even headers not required, do you think is correct?
In that case you can try adding
FOREACH( INCLUDEFILE ${LIB_PRIVATE_HEADERS} )
FILE(RELATIVE_PATH REL_INCLUDEFILE ${HEADER_PATH} ${INCLUDEFILE})
GET_FILENAME_COMPONENT(REL_INCLUDE_PATH ${REL_INCLUDEFILE} PATH)
INSTALL(

It seems to do what intended, but test if it works and it suits your

it even simplify the process to have directly the appropriate

Its the inconsistency that concerns me, if you are compiling against
the in source version of the OSG, then move across to using an

I introduced the api/* directories to help hide the expected

Yes after thinking to this solution it can cause a lot of other

I modified the project files to work correctly but during linking, I receive unresolved symbol (_xmlFree) from the daeLIBXMLPlugin. I did a quick google and some others were able to resolve this by using the static version of libxml2 but that was unsuccessful as well. (If you are familiar with dev studio it was the issue where libs are built with conflicting Code Generation settings). Anyway, has anyone else successfully built the collada plugin on windows? Have any suggestions on resolving this? We have a model that is animated and we'd like to export it to collada and read it into osg.

I'm projecting another texture onto that terrain via a TexGenNode. My projected texture only encompasses a small portion of the entire terrain.

Re: [osg-users] Windows CMake install problem
Hi Luigi,
I have already checked in a change to src/osgViewer/CMakeLists.txt so
the it installs the relevant platform specific header files. Files
like GraphicsWindowWin32 are useful when users want to get window
information, or use the inherit window data functionality.
The only problem with my changes are that it doesn't honour the
api/Win32 nesting of directories within include/osgViewer.

It seems that while the selection of the sources (.cpp) files to use is

If we just add installation steps for the LIB_PRIVATE_HEADERS, we
install even headers not required, do you think is correct?
In that case you can try adding

If you link against the static library (called libxml2_a.lib), you shouldn't get the error. If you want to link against the libxml2 DLL, you'll need to rebuild the DOM. First remove the constant LIBXML_STATIC from the preprocessor defines in LIBXMLPlugin.vcproj, and if you're building the DOM as a DLL (I'm not sure how OSG uses the DOM), change it to link against libxml2.lib instead of libxml2_a.lib. This is all rather confusing... I should write up some documentation for this. Gerrick Bivins wrote: Hi Robert and Anders, Yup. libxml2 is what I'm linking in. So is the solution to update collada dom? Ouch. I was hoping to be able to just use the installer for this easy update rather than the brute force route and building collada dom...Oh well. biv ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/

However on loading of .osg the lightmap appears to be recopied into memory each time it is read in the .osg file, so large amounts of ram still needed on copies of the same bitmap data. Question?

Thank you for the explanation, Tim. It makes sense to me now. Unfortunately, your suggestion didn't work. It caused my projected texture to disappear. Just in case I explained my goal wrong, here's another shot: I want my underlying terrain to always retain its original colors and alpha value (of 1). I only want to control the opacity of my projected texture. With an opacity of 1, the projected texture will completely occlude the terrain. With an opacity of 0, the projected texture will not be visible at all.

RE: [osg-users] Collision detection
The BS tree that OSG uses for culling is accessible through the osg::Node-getBounds() method. For a node, N, N-getBounds() returns a minimal bounding sphere that holds all bounding boxes for drawables that are descendants of N. There are a few caveats to this though, with respect to AutoTransforms, LODs, and probably some other node types, where drawables' dimensions are adjusted as a function of the some other control, such as the eye. Raw bounding box information is not directly accessible through the interface provided by osg::Node. There was a topic that came up a few weeks ago where a NodeVisitor was used to compute a bounding box, so you may want to check that. If spheres are good enough, I'd recommend looking at getBounds() to see if that is adequate. As for the locality problem: trying to pair objects based off their spatial orientation is a high level task outside the scope of OSG. There might be an optimizer in the osgUtil library that can improve spatial organization, but I don't know of one since I haven't used them.

[osg-users] Re: Windows CMake install problem
So, I'm really behind on this discussion thread. I need some clarification on things. On install, where are the private headers supposed to install to (if at all)? So here's the thing. I introduced the LIB_PRIVATE_HEADERS because I was anticipating something might need to be done with them, particularly for the OS X frameworks. The OS X framework structure has a special designated section just for these things. But there are rules/limitations surrounding headers in general. So my presumption is that the end user never #include's a Private header directly (hence 'private'). A public header might need to #include a private header. If this is the case, I think the #include in the public header needs to be like: #include osgViewer/FooPrivate.h So if a public header has a api subdirectory in this string, e.g. #include osgViewer/api/FooPrivate.h, I believe it will break the framework badly.

Re: [osg-users] Tessellator build failed under cygwin
Dang I found it. Robert I got around this error keeping Tesselator from building by using the current SVN (as I mentioned trying to test the new Windows hag you fixed to see if it helped Cygwin) and then because of some additional parameters I found when using the old GNUmakefiles I added these option to all the CMAKE_CXX_FLAGS.. Options: -DWIN32 -DNOMINMAX -W -Wall -mnop-fun-dllimport -DOSG_LIBRARY and bingo - Tessellator built after that. I don't know which fixed it or why or even if this is a correct fix but it built. I also to get a complete build had to change the reference for wsock32.lib to wsock32.a in Cmakelists.txt in the main trunk of OSG. I think this needs to be (but I don't know MingW) wsock32.lib for MingW and wsock32.a for Cygwin (but I don't know Cygwin either). I also had to change the condition for whether to add osgviewerMFC in the examples/CMakelists.txt so that it included a check for UNIX (which did nothing) along with its check for WIN32 whcih then added osgviewerMFC. Unfortunately after all this the test apps like osgviewer and osganimate and osgwindows still hang on close in Cygwin but at least it compiles again. I notice as well under the old GNUmakefile builds that when linking say osgUtil there were options as follows: c++ -O2 -W -Wall -L../../../lib/CYGWIN32 -L/usr/local/lib -shared -Wl,--out-implib,libosgUtil.dll.a -Wl,--export-all-symbols CubeMapGenerator.o CullVisitor.o which was represented in the old make/makedefs as: SHARED= -shared \ -Wl,--out-implib,lib$(TARGET_BASENAME).dll.a \ -Wl,--export-all-symbols I assume these would go in the CMAKE_SHARED_LINKER_FLAGS but how would you represent them and do we need them. bk ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
[osg-users] Improving the performance of video texture rendering
Hi,
In our application, we are using OpenSceneGraph to render 8 video
streams simultaneously. We need to achieve 25 FPS, but at the moment are
getting around 18 to 22 FPS. There are a few things we can optimise,
such as the video decoding, threading, etc. Getting better hardware is
not out of the question, but as a first step, does anyone have any tips
for improving the performance of the texture rendering side of things?
I've got two NVIDIA Quadro FX 3500 graphics cards (connected to a screen
each), two dual-core AMD Opteron 2214 Processors, and 3GB of RAM,
running Windows XP 32 bit. Our application displays 4 video streams in
each screen.
To draw the video, we're using a TextureRectangle, and updating its
Image whenever the video data changes.
Image* image;
if(m_textureRect-getImage() != NULL) {
image = m_textureRect-getImage();
} else {
image = new Image();
image-setPixelBufferObject(new PixelBufferObject(image));
m_textureRect-setImage(image);
}
image-setImage(m_imageWidth, m_imageHeight, 1, 4, m_pixelFormat,
GL_UNSIGNED_BYTE, imageData, Image::AllocationMode::NO_DELETE);
For our sample video:
m_imageWidth = 720;
m_imageHeight = 576;
m_pixelFormat = GL_BGRA;
I've been looking into GPU/OpenGL profiling tools. We've got gDEBugger,
and I was looking at NVIDIA NVPerfKit (but our graphics card doesn't
appear to be compatible). Are there any other tools worth looking at?
Thanks,
Shalin
