Re: [osg-users] how can I ignore the UpdateCallback
Hi,
Specifically, AnimationPathCallback has a setPause method.
More generally, you can control which nodes OSG updates (i.e. visits
during an updateTraversal) using node masks. Look at the methods
osg::NodeVisitor::setTraversalMask and validNodeMask for an explanation
about how it works. In short, visitors have a bit mask (defaults to
0x) and nodes have a bit mask (defaults to 0x). If the
bitwise and operation between them gives a result other than 0, the node
will be visited. If the result is 0, the node will not be visited. (Really
the node wil be visited but the update callback will not be called). Node
visitors has also a Node mask override that allow you to override the node
mask to force the node to be visited ignoring its mask.
Hope this helps.
Himar.

AnimationPath runs off of sim time, so if you mod your app to not increment
sim time, then the animation will not play.

Re: [osg-users] how can I ignore the UpdateCallback
Hello,
Paul, when I stop the sim time then stop all animation. Or is it a wrong
guess?
Himar, I tried to change the NodeMask and the viewer did not draw the
node. I think all functions were ignored, but I would ignore the update
callback only.
I have an idea. Can I Copy the update callback to event callback and
after this I remove the udate callback. Now I can define a event to
run the event callback?

Thank you,Gordon. Seems, I need to change my design. Originally, I just want to set plant leave's color,ambient and diffuse value in palette, and change one set to another at runtime. for now, I don't know if I need to write them in an xml file. If I do, then modeling is an troublesome thing, since I would have to manually write down every color set. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=18318#18318 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] [osgOcean] Member var initialization bug in Cylinder
Dear all,
Here is a simple fix for an error in the Cylinder class of the current svn
trunk version of osgOcean. Yesterday's revision 156 introduced member vars for
the Cylinder (_radius, _steps, etc.) but these were not initialized in the
Cylinder constructor, resulting in uninitialized vars being passed to the
build() method, resulting in a bad_alloc crash :-)
Kind regards,
Ruben Smelik

[osg-users] [osgPlugins] Freetype and JPG plugins problems
Hi, yesterday I downloaded the last dev release of osg (2.9.6) and now I'm experiencing problems with some plugins. My scenario is simple: just load a .osg file with osgviewer.exe. The dir that contains my osgviewer also contains all osg DLLs and 3rd parties DLLs, the models and textures dirs and then all the plugins (I tried to put the plugins both in the osgPlugins-2.9.6 dir and in the same level of my osgviewer.exe) In all cases it looks like that every required plugin is successfully found but: 1) if I put the plugins in osgPlugins-2.9.6, then the loading of osgdb_osg.dll fails, don't know why... 2) if I put the plugins in the same dir of osgviewer.exe, then loading of osgdb_osg.dll is fine, but loading freetype and JPG plugins fails (but for example RGB plugin is ok too). Regarding this case, looking at the generated 'manifests', I suspect that the problem could be in the different versions used by what I build (CRT's minor number 4053) and 3rd parties binaries (CRT's minor number 762)... Any suggestion or ideas? Should I re-built 3rd Parties binaries? (I hope not) Regarding my building environment: I built everything (excluding 3rd parties binaries) on Vista 32 bit and VC++ 2005 Express Edition SP1 (regarding 3rd parties binaries I downloaded the ones built from VS80 SP1). By the way, running the application on the building machine works fine in both the scenarios. Thank you!

I try to write osgAnimation Callbacks into an osg file but don't get it to

All available osgAnimation examples create executables, but no osg files.
When I use osgDB::writeNodeFile( *someScene , someScene.osg ) ;
instead of creating a viewer, the code block between UpdateCallbacks
parenthesis stays empty in the resulting osg file, but this is where I
would expect keyframe and channel data. The Blender Exporter is also not
helpful, as it uses its own mechanism to write out osg files through
Python.
Can anybody explain / post / create an example that writes a simple
osgAnimation into an osg file, please or point to information on that ?

You might try to: - install the redistributables for visual c++ 2005 SP1 on the deployment machine - use the dependency walker tool on the target machine and open the osgdb_png.dll and osgdb_freetype.dll files. Check if there are any unresolved dependencies there. - install other redistributables as well, if somehow the 3rd party package references more than a single CRT, e.g. vs80, vs90, vs90 SP1. The RGB plugin works since it has no external dependency. Other plugins with pure C dependencies will work as well. The problem is always with the extra c++ DLLs required by c++ DLLs you did not build by yourself. Hope you manage to get it running without having to recompile your dependencies by yourself - which is time consuming but quite less frustrating w.r.t the problems you have.

Re: [osg-users] memory leak in osg 2.8.2 ?
The trick, if I can call it that, is to perform the leak check in the
destructor of the last destroyed object. Works for me!
You just need to make sure your global heap check object is created before OSG
gets to make its evil singletons ;-) . e.g.
Code:
struct TheEnd
{
~TheEnd() { CheckForLeaks(); }
};
TheEnd theEnd;
int main(int argc, char* argv[])
{
osgViewer::Viewer viewer;
viewer.run();
return 0;
}

Chris

Re: [osg-users] [osgPlugins] Freetype and JPG plugins problems
Thank you for your help, I already tryed to set the notify level to debug and, as far as I understand, plugins are always discovered but the only error message I see is DynamicLibrary::fail loading ... no further detail is provided. I just had to try to install the redistributables for Visual c++ 2005 SP1 on the deployment machine (even though I was providing my application with a manifest and corrensponding CRT), so I tried it but again this not solved the problem...actually on every deployment machine the installation of the redistributable looks not so 'polite' because it strarts but doesn't display a completion message, so I'm not so sure about a successful installation... Tried also the dependency walker tool on the target machine, and some DLL are not found but they are the same as the RGB plugin that works. The missing DLL is DWMAPI.DLL, don't know what it is for... Don't know if this could relate to this problem, but in CMake I see the USE_3RDPARTY_BIN set to ON by default...what does it mean? Thank you again...

[osg-users] [patch] PThread.c++ creation error, lower stack size limit
This was against 2.8.1, but I see the trunk is identical.
Any issues with using PTHREAD_STACK_MIN?
http://www.opengroup.org/onlinepubs/9699919799/functions/pthread_attr_getstacksize.html
I was trying to create a lot of threads under 32 bit Linux, but could
only create 376, then the program would hang.
376 * 8MB stack per thread = 3008 MB
The stack size allocated per thread blew the process address stack.
To get more threads you have to specify a smaller per thread stack,
but while the Thread::start says it will limit the stack size to the
smallest allowable stack size, it won't let it be smaller than the
default. I included the limits.h header to use PTHREAD_STACK_MIN as
the minimum stack size.
As for the deadlock, if the pthread_create failed, the new thread
doesn't exist and doesn't call threadStartedBlock.release(), so the
existing thread deadlocks on threadStartedBlock.block(). Only block
if the thread was started.

The reason you get no update callback in the .osg file is that
osganimationnode uses a custom callback, AnimtkUpdateCallback, that the
.osg writer doesn't know about.
From the OpenSceneGraph-Data .osg files that have animation (such as
robot.osg), it looks like osgAnimation::BasicAnimationManager is
supported, so you could start with using that instead of
AnimtkUpdateCallback.

[osg-users] I'm lost the UpdateCallbacks
Hi,
I have a osg-file with UpdateCallbacks:
[...]
MatrixTransform {
DataVariance DYNAMIC
name Kugel01
nodeMask 0xff
cullingActive TRUE
UpdateCallbacks {
AnimationPathCallback {
DataVariance DYNAMIC
[...]
I load the file with the line: osg::ref_ptr ::osg::Node fileScene
= osgDB::readNodeFile(path);
I see the scene, but the fileScene has no UpdateCallback. What is my
mistake? Anybody an idea? When I load the viel with the
osg/bin/osgviewer then it works fine?
I have write a NodeVisitor to check the UpdateCallback:
-
class FindUpdateCallback : public osg::NodeVisitor
{
public:
FindUpdateCallback():osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{
}
virtual void apply(osg::Node node)
{
::osg::ref_ptr ::osg::NodeCallback ucb =
node.getUpdateCallback();
if(ucb.valid()) std::cout YES std::endl;
else std::cout NO std::endl;
traverse(node);
}
virtual void apply(osg::MatrixTransform node)
{
apply((osg::Node)node);
}
virtual void apply(osg::Group node)
{
apply((osg::Node)node);
}
virtual void apply(osg::Geode node)
{
apply((osg::Node)node);
}
};
It prints always NO.
Cheers,
Martin

Re: [osg-users] Cameras View Matrix - I am perplexed

So, if some data is shared between multiple threads, it may be loaded into multiple caches all at once. If one thread makes a change, the value cached by the other core/thread is now stale. Synchronizing flushes the caches, so any pending writes are made to the main store. The next time anybody tries to read that value, it won't be in their cache and the data will be read from the main store. Just to clarify: Yes, CPUs usually have their own caches and data can be different in the different caches. However, this isn't what synchronization is solving. This problem (cache coherency) is handled by the hardware. The reason you need to do locking is because two threads (which may or may not run on separate cores) might alter the same data in ways so that the result is no longer sane. You might be right. If you want to rely on that, then you really need to know what hardware you are running on and what the memory model is. I don't believe C++ has a standard memory model. The last time I really dug into this was a couple of years ago. If I remember correctly, the Intel chips of that era promised only a very weak memory model. In practice, they had a much stronger memory model. In fact, the only cpu that I know had a very weak memory model was the Alpha and those haven't been around for a while now. I thought cache coherency depended on cues from the software. For example, acquiring or releasing a mutex forces any pending writes to complete then flushed the caches, marking a value as volatile prevented any caching, etc... Is this wrong?

Re: [osg-users] SVN commit bottleneck
Hi Chris, On Mon, Oct 12, 2009 at 6:49 PM, Chris 'Xenon' Hanson xe...@alphapixel.com wrote: Ok. I can understand that. Are there any aspects of submission review that could be outsourced? I've already outsourced aspects of the submission review that are the easy and most productive areas. osgAnimation and the Xcode projects are maintaining themselves quite well. The branches are rather less active though, with plenty of engineers with write access but all but me and very occasionally Paul Martz active. The idea of have a range of engineers to have write access to branches and with the ability to taken the driving seat with making stable releases is something we discussed and put into place around a year ago. Alas apart from Paul Mart'z 2.6.1 release there hasn't been any impetus from the community to drive this forward. The key point is that I was trying to step back from having to be the impetus behind releases and to allow others to take the reigns. I think this is a good plan. I'm not sure I can volunteer to be the sole driving force behind a release (in fact, I know I can't) but it's possible we could assemble a few people that together could do so. We'll without volunteers pushing it forward then it'll just fall back to myself to do when available. Is there anyone reading this who could help get the next release out as part of a group? I'm been away for almost a week and no other engineers and jumping in so I guess not at this time. Do we have a release procedure document? Not yet. Cmake actually now does most of the hard work for us. It's just a case of make tag-test Then when you're happy with what it's going to do with the subversion branch: make tag-run Then it's a case of updating the website with source archives and binaries. But the real task is not the actual release but the effort in coordinating everyone, doing testing and reviewing and merging submissions. It's a community process that is out there in the open. As a general note, we don't even have people coming forward volunteering to drive releases, so writing detailed docs would rather go to waste... The thing to do is find volunteers and let them be assisted by myself and others on the first few minor point releases they do and document/evolve things to make them more streamlined as you go along. appropriate thing to do. For these reasons I'm more inclined to believe that having a single gate keeper of the source is far more of an asset that it is a bottleneck. I can understand that. As I mentioned above, perhaps it's worth pursuing refactoring off any duties short of the actual SVN commit. Are there other things you think could be done by the community? Um pre testing of submissions is about all we can do, this is already done on occasional submissions that are of interest to others that can't wait for me to get to it, this certainly helps, but it's very occasional. Everyone has there own projects to work on though, so I really don't expect that others will happily devote time to just routine pre-review of submissions. The bottom line is that people have to have an itch to scratch. Personally I wouldn't say review of submissions is a significant bottleneck for the project. It's an occasional bottleneck that will affect different engineers at different times. In terms of workload submissions isn't the biggest problem I face in a managing the project - it's keeping up with general support and driving releases. It's this big stuff that I've been able to partly take a back seat on - general support is handled pretty well in my absence, but driving releases has been close to a void. Even when Don was around it was still me driving almost all releases of OpenThreads, Producer and OpenSceneGraph. The door is open for others to dive in a help, but if members of the community are too busy writing great software then so be it, I'm happy to keep chugging along, but the pace will have to fit in with my own professional and personal constraints.

Re: [osg-users] New OpenGL texture object and buffer object pool support
Hi Cedric, osgViewer/core OSG should already have all the mechanisms available to do clean up of the scene graph and associated OpenGL objects correctly - and in fact it's possibly these existing mechanisms that are causing the failure in question. I suspect the solution will come from studying exactly what is happening and when during the destruction phases of the graphics threads, graphics context, scene graph and viewer, something small is likely amiss - the challenging is pinpointing exactly what this something small is... Once I've progressed the OpenGL ES 2.0 port a bit further I'll revisit this issue, my expectation is that it'll just require a couple of hours of TLC. Robert.

I just had to try to install the redistributables for Visual c++ 2005 SP1 on the deployment machine (even though I was providing my application with a manifest and corrensponding CRT), so I tried it but again this not solved the problem...actually on every deployment machine the installation of the redistributable looks not so 'polite' because it strarts but doesn't display a completion message, so I'm not so sure about a successful installation... Tried also the dependency walker tool on the target machine, and some DLL are not found but they are the same as the RGB plugin that works. The missing DLL is DWMAPI.DLL, don't know what it is for... Don't know if this could relate to this problem, but in CMake I see the USE_3RDPARTY_BIN set to ON by default...what does it mean? Thank you again...
