[osg-users] about the debug version of osgdemd.exe
Hi all,
I got VPB r924 from SVN, and built it with VS2005. The release version
worked smoothly. But when ran the osgdemd.exe with osg2.6.0, the error
Application initialization failure jumped out and could trace to file
osgDB/registry:
class RegisterDotOsgWrapperProxy
{ public:
RegisterDotOsgWrapperProxy(osg::Object* proto,
const std::string name,
const std::string associates,
DotOsgWrapper::ReadFunc readFunc,
DotOsgWrapper::WriteFunc writeFunc,
DotOsgWrapper::ReadWriteMode
readWriteMode=DotOsgWrapper::READ_AND_WRITE)
{
if (Registry::instance())
{
_wrapper = new
DotOsgWrapper(proto,name,associates,readFunc,writeFunc,readWriteMode);
Registry::instance()-addDotOsgWrapper(_wrapper.get());//the
error jumps out
}
}
I don't know how to avoid this error. I must have a debug version to
trace some process. Anyone do me a favor? Thanks very much.

Re: [osg-users] Compile Context Background Thread Question

So when OSG_COMPIlE_CONTEXTS=ON then a background thread traverses the
scene graph and compiles the un-compiled display lists using a different
OpenGL context than the render thread's, which prevents the render
thread from having to do the display list compilation. Is that correct?
The compile context just sits with its own GraphicsThread waiting for
GraphicsOperations to be passed to it, when they are other threads
want their GL objects to be ran for them then simply create an
appropriate GraphicsOperation and pass this to the compile Context's
GraphicsThread. The DatabasePager does this with the following code:
for(ActiveGraphicsContexts::iterator itr =
_pager-_activeGraphicsContexts.begin();
itr != _pager-_activeGraphicsContexts.end();
++itr)
{
osg::GraphicsContext* gc =
osg::GraphicsContext::getCompileContext(*itr);

gt-add(new
DatabasePager::CompileOperation(_pager));
}
else
{
gc-makeCurrent();
_pager-compileAllGLObjects(*(gc-getState()));
gc-releaseContext();
}
}
}
Please note that all operations are pushed to the graphics thread of
the compile context, the graphics thread itself does traverse
anything, it's not an active class that does stuff on its own, it just
sits their waiting for you to give it work and it does it, if it
doesn't have anything to do it just goes to sleep.

Re: [osg-users] Draw threads serialized by default?
Hi Alex, I have been planning to make the processor affinity configurable, but just haven't had a chance to do this yet. This certainly isn't a feature for 2.8.1 as the minor point releases are contain just bug fixes. This feature will have to wait till the 2.9.x dev series and the final 2.10.

I can't explain why I get better performance on my second processor, but the only way I was able to make the draw thread run on my second processor was by modifying the osgViewer::startThreading() function because I found that calling the draw thread's setProcessorAffinity() function had no effect after the thread started running.

HI Todd. osgViewer already sets the affinity, and indeed this makes a big difference to performance when running multi-threaded, mult-context/mulit-gpu work. The draw dispatch serialization that osgViewer::Renderer does on top of this makes even more difference on PCs I've tested. I would guess that a decent multi-processing architecture like the Onyx would scale much better, it might be that some very high PC hardware set ups would also scale much better (the AMD 4x4 motherboards spring to mind as a potential candidate for this better scaling).

Furlong t...@inv3rsion.com wrote: Robert, The post of yours that Paul linked to sounds very similar to something we saw with VR Juggler OSG a while back: terrible performance with OSG apps that had parallel draw threads. In our case, VR Juggler manages threading, but the same may apply to OSG with osgViewer. For us, it turned out that we had to set the threads' affinity to lock them to a particular CPU/core. The Linux scheduler moved the threads around and thrashed the cache, I believe. Setting the affinity boosted the parallel draw performance back up. The solution we ended up with is twofold: 1. Add a default behavior that sequentially locks draw threads to CPU cores (0,1,2,etc. repeat) 2. Use an environment variable to override the default behavior (VJ_DRAW_THREAD_AFFINITY, a space-delimited list of integers). The default behavior is good for most users, but we can squeeze out a little more performance by tweaking the environment variable. For a system with two draw threads and two dual-core CPUs, the default behavior locks the draw threads to CPUs 0 1, but we get slightly better performance if we set VJ_DRAW_THREAD_AFFINITY=2 3.

Now that I see it's ON by default, I half wonder if this is a bug. Wanted to check with you: should I change the documentation, or the code? Which is right? The settings has been ON since I introduced the option to serialize the draw dispatch. Just before the 2.6 release I did testing at my end and still found serializing the draw dispatch to be far more effiecent on my Linux/NVidia drivers so I left the option on. In the original thread when I introduced the optional draw mutex into the draw dispatch I did call for testing on the performance impact but I didn't get sufficient feedback to make a more informed decision than just basing it on my own testing. I would still appreciate more testing, as I'd expect that best default setting to vary on different hardware and drivers - I for one would love to see better scalability in driver/hardware.

Re: [osg-users] about the debug version of osgdemd.exe
Hi Xuex,
I have never seen a report about problem like this before, so don't
really have any prior experience to bare on it. The code in question
has been heavily used by all users for many years without problem so I
would suspect a build issue of some kind.
I will be making another dev release of VPB in the next week or so,
and this will match to OSG-2.8.0, and would be a better base for you
own testing. Right now I'd recommend using the svn version of VPB and
OSG-2.8.0 as there have been lots of improvements to OSG since 2.6.0.

Hi Christophe, If you run the install target then you should get a single set of include and libs placed together, with Config files in place. If you don't install after building, and do an out of source build then the config files will be separate from the OpenSceneGraph/include directory, in this instance you will need to point you own app building to the our of source include directory.

Re: [osg-users] OSG 2.8.0 compilation
Indeed ! My warning issue is linked to that Config file location problem. I had the time to try the following thing before Robert answer : if I move both Config file to the proper location BEFORE (re)building OpenSceneGraph, afterwards my end-user application links with it with no more disturbing warnings. I didn't pay attention before (with 2.6.1) about these Config files or this INSTALL target, maybe things have a bit evolve in between (?). Anyway knowing all that averything work fine. Thanks to all.

If you don't install after building, and do an out of source build then the config files will be separate from the OpenSceneGraph/include directory, in this instance you will need to point you own app building to the our of source include directory.

Hi, create an osg::Image (you don't need to allocate image data portion), point the Image at your own data. Create a Texture2D/TextureRect, call setImage on this with your osg::Image.

The best way to stream data to a texture is via the osg::ImageStream class that subclasses from osg::Image. In your own code subclass from osg::ImageStream to wrap up your OpenCV code that reads the image data, then set the Image's data pointer and call image dirty on the image stream. Then just attach your ImageStream object to any texture you want, the OSG will automatically download the data for you in the most efficient way (use subloading and PBO's). For examples of subclasses osg::Image have a look at the xine or quicktime plugins.

Re: [osg-users] Problem with 2D and 3D text in the same scene
Hi Frank Problem: osgText::Text and osgText::Text3D use the same font file. The first really load the file and obtain an osgText::Font object, the second use the cache created during the first load of the font file, and so obtain an osgText::Font object instead of osgText::Font3D object. To obtain an osgText::Font3D object, osgText::Text3D call osgDB::readObjectFile(...) with an option to specify the plugin we want an osgText::Font3D instead of osgText::Font. Generalised Problem: In osgDB::Registry, loaded file cache is referenced by the name of this file, so if I load a file with some options, and the cache already contain object for this filename, I obtain an object potentially not loaded with my options. Behaviours: Cache management is delegate to osgDB::Registry, but cache coherence (load a file with option then reuse it, deactivate the cache when load a specific file or don't cached the loaded file) is user's responsibility. Text3D case: Delegate the cache coherence of font file in osgText to the user is not a good idea. So to fix this I think to 2 solution: - never use the cache when load a font for a Text3D. Just because to load a Font3D, we use option in osgDB::readObjectFile() - move osgText::Font3D implementation in osgText::Font, suffix ex-Font3D method with 3D in osgText::Font (so osgText::Font3D::getGlyph() become osgText::Font::getGlyph3D() ) And so Text and Text3D use the same osgText::Font object which contain 2D and 3D glyph.

I will be making another dev release of VPB in the next week or so,

Re: [osg-users] VS 2008 packages + 3rdParty_Win32Binaries_vc90 inftp
Hi Mattias, About the 3rdParty VC9 SP1 binaries... Release build seems fine (no warning nor errors). Debug build still shows some warnings: - osgdb_tiffd.dll: warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library - osgdb_jpegd.dll: warning LNK4099: PDB 'vc90.pdb' was not found [...] linking object as if no debug info From what I can see, the problem with osgdb_tiffd is that it's linking to the release build (i.e. libtiff.lib). Hence it's an OSG CMake problem, not a 3rdParty lib problem (especially that TIFF_LIBRARY_DEBUG in CMake cache correctly points to the debug library). This should be fixed; mixing release/debug CRTs is never a good idea. The debug info warning has been fixed for all libraries except libjpegD.lib. Probably just has to be recompiled with /Z7 ?

So I am using the same texture filename, in more than one Geode. The data actually comes via the 3DS converter, organized in layers. Interestingly enough, the ASCII OSG file loader which references a texture file actually does check to see if the texture file is loaded before attempting to load it. This isn't done with the IVE loader which blindly loads the same texture data multiple times. - Andrew ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] [osgPlugins] OpenFlight-Plugin - Subfaces could not be read by OpenFlight-API
Hello, i'm currently using the osg-OpenFlight Plugin to generate flt-files including Subfaces (- osg::PolygonOffset). Exporting and importing with osg works fine, but using the generated flt-file with the Multigen openFlight API leads to missing subfaces. For example when opening the osg-exported flt-File with MultiGens Creator, textures which were marked as subfaces are flickering. Loading the same file in an osg Viewer application: everything looks fine. (Saving the file with Creator and then opening it with osg Viewer - flickering.) Something about exporting subfaces seems to be not confirm with the api. I'm using Osg 2.7.6, and MultiGen OpenFlight API 3.2 (Creator 3.3). I need to use the api to convert from OpenFlight 16.1 to 15.7. But I also need Subfaces. Would be great if anybody could help me. Thx!

[osg-users] Destroying osgViewer::Viewer leads to strange effects in texturing
Hi, i'm getting some strange effects if using two osgViewer::Viewers like this: 1) Create viewer1 and render different parts of scene1. Destroy viewer1. 2) Create viewer2 and render scene1. On some objects textures are missing or plop in and out, when moving in the scene. If I do not destroy the first viewer, everything works fine. The effect is even more visible for this setup: 1) Create viewer1 and render diffrent parts of scene1. Destroy viewer1. 2) Create viewer2 set two groups as sceneData (group2 is child of group1). Set scene2 as child of group2 and render. 3) Remove scene2 from group2 and add scene1 instead. Render with viewer2. Here some objects are entirely invisible and textures plop in and out. If viewer1 is not destroyed, everything works fine. Could there be a bug in osgViewer::Viewer concerning its destruction (cleaning up)? Do you have any other idea why the above mentioned effects occur? Seems like something gets messed up with the states?

Re: [osg-users] Destroying osgViewer::Viewer leads to strange effects in texturing
Hi Katharaina, The osgViewer tries it best to clean up the scene graph when graphics contexts get deleted, but it needs to have a handle on the scene graphs to be able to do it, removing the scene graph from the view prior to deletion of the graphics context will hide this scene graph from the viewer so full cleaning of the scene graph won't be possible. In this case you'll have to subgraph-releaseGLObjects() on the subgraphs that aren't attached prior to closing the viewer. Later rev's osgViewer are better at handling the clean up, but don't solve the case above where the scene graph is removed prior to the viewer destruction without any clean up. You make no mention of which version of the OSG you are using, so perhaps you are seeing an older bug rather than just the above clean up issue. Either way it's best to make sure you are using OSG-2.8 as it contains a range of bug fixes/improvements. Robert.

If you could email me a small .osg file that reproduces the problem, I could take a look.

Re: [osg-users] Problem with 2D and 3D text in the same scene
Hi Robert I think merging the osgText::Font and Font3D implementations would be the cleanest approach. I think too ... but ... Another, more hacky approach would be to postfix the font file name by .Text3D or something similar and then have the freetype plugin return Font3D when it detects this. This solution is really smart, it not break the scalability of osgText. I don't know which use can be done with a font except 2D or 3D glyph, but this keep the door open to other thing. osgText::Text3D have to ensure that name of font file is ended by .Text3D and font file cache coherence is not delegate to the user. I have try this solution and work fine. I prepare a submission if you prefer the second solution. Or implement the first one otherwise. As you want. David Robert.

With everyone volunteering their own local area as a venue might I suggest finding a conference that osg users would otherwise attend, then piggybacking a meeting off this.

Re: [osg-users] What about User-Meeting in Europe - osgInEurope?
Hi all, the idea about a video conference sounds nice. I am not sure, which techniques are currently exists there to make it possible, but we could try to find out. I think, if we find enough people for a face-to-face meeting, we could include a video conference into the conference program. Of course for this we would require a conference room with high speed and stable internet connection. I would propose to wait until 01.04.2009 which city will win the votes. Afterwards we will try to find there a nice place for the meeting. Per video conference we could put the meeting online and connect other groups (from other cities) as well. cheers, art P.S. Robert, is it fine with you, if I put some announcement about the upcoming osgInEurope somewhere under www.openscenegraph.org? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=7067#7067 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
