Re: [osg-users] Easiest way to bundle an OSG app
Hi, to deliver my software, I use MS Visual Studio setup projekt. I add my complete osg binary folder (of course only release build) to my project as well as my application binary to the project. The dependencies regarding the compiler etc. are solved by VS. Why do I add my complete large binary folder? Well, I can't foresee which models my clients will use, so I deliver all plugins. Maybe this is'nt the best solution, but it's fast to build, easy to use and thanks to broadband, the transfer of the installer is fast enough.

[osg-users] Mutex and Windows XP - Hang
Hi, I have to secure a std::vector for multithreaded access and used a Reentrant Mutex for this. (btw: Whats the diferent between reentrant mutex and mutex?) On my development Platform (Vista) this works great. On windows XP 32 bit, the application hangs on this mutex, although it is not locked. What is the best way to secure access to a std::vector which should run on all platforms? I' have seen this scopedLock is often used, by I have no clue what this is about and how it works.

[osg-users] outputsize of osgb and osgt
Hi, I have written a clsuter/network module to transport nodes over network (atm only nodes are serializable, not osg::objects). I have play a bit with the zlib compressor and the binary and ascii version. My result was a larger binary result as ASCII result of the identical node. I didn't expect this, I always thought ascii format is larger than binary.. Do I miss something, or I just my binary cluster implementation buggy? My Processing-pipline is: - serialize node to std::stringstream - extracting string of stringstream and pass it as chr* to the socket. btw: At the end, when my code is robust and well factored, is there any interest to add a cluster-node to OSG to allow highlevel UDP stream over network? Something like: Code: osg::cluster mycluster = new osg:cluster(); mycluster-init( port, destination address, useCompressor, asAscii ); mycluster-sendNode( mynode); .. mynode = mycluster-readNode(); Thank you!

Re: [osg-users] outputsize of osgb and osgt
Hi Robert, my serialized sizes are: Ascii format: 137 byte binary format uncompressed 217 byte (!) binary format compressed 107 byte. 6 Month ago, I implemented 2 prototypes (TCP, UDP) . My result was, that TCP is not as fast as UDP, but it was the only possibilty to (nearly) sync the different channel's swap at final draw callback. On UDP I currently use broadcast, but thats not mandatory. Because of its unreliability, my UDP approach is fire and forget. So the slave tries to get as much as possible packets (to avoid framentation, the datacontainer must be smaller than the max payload of an UDP datagram) and uses the newest one for processing. My TCP approach was to send the frame information at the beginning to all slaves, then waits for all slave to report as ready, and if every client is ready, the sends the swap command to all clients. This solution was quite slow, so at the moment I focus an a UDP solution. I don't know which functionalities you would include in a cluster Node. Only transporting a transport container over network, or also complete frame sync? In my application I use to callbacks, eventdraw callback and finaldraw callback. At these two positions in the frame, the callbacks act depending of the role as master, slave or as standalone. They send information to slaves, receive information from master or do nothing. To make the cluster transparent to the scenegraph independent from the role, I implemented a dataIO interface which they query. Beyond this interface, there is the cluster driver (slave) or cluster driver + externalLink driver (master). The ladder connects the visual to its external control source, which can be a flighsimulator, a control program or anything else. My current transport content is: - viewmatrix - variables which are used of my objects updater classes - list of executer command, which can transport a command as enum and some parameter (e.g. to change weather at all clusternodes) This is my current approach. My project will be openscource in some days/weeks (depends on my time to set up my trac environment). Because you are under heavy load, maybe it is best If I continue my project, and when its published, you can take a look on it and we can discuss how man of the architecture could be abstracted, refactored to your wishes and included as cluster framework...

[osg-users] Enhancement of osgDB::serializer
Hi Wang, I managed to get the serializer working. I have some proposals to enhance the serializer: 1. It is only possible to serialize objects inherited from osg::Node or Images. Classes just inherited from osg::Object are not handled. There is a Function Code: WriteResult writeObject( const osg::Object object, std::ostream fout, const Options* options ) const but this function only tries to cast into image or node and fails otherwise. It would be great to provide also serialization for osg:Objects. 2. documentation: I have a list of questions/ common mistakes. Should I modify the wikipage directly (login/permission required) or should i send you the list? Thank you!

Re: [osg-users] osgTerrain
Hi, to render terrain in OSG, there are several methods. First of all you have to choose between preprocessing your terrain for high performance and rendering on demand for high flexibility and low performance. For the first method, you can use VirtualPlanetBuilder (an other project of OSG), which creates an database in the osg standart format .ive For the second approach, you can use the project osgEarth, which allows the define project files, in which you can select several driver and source formats. This way, your DEM und orthophoto is processt during rendering of course you have to pay this flexibility with performance So, as next step you could google after both projects and dive into them.

Re: [osg-users] How does ADD_LIST_SERIALIZER work?
Hi,
Well, I have defined my wrapper for my testclass and it compiles, unfortunately
it is not serialized.
My testcall is:
Code:
dataIO_transportContainer* test = new dataIO_transportContainer();
test-setFrameID( 22 );
std::ofstream myOstream(test.txt );
osgDB::ReaderWriter* rw =
osgDB::Registry::instance()-getReaderWriterForExtension(osgt);
if ( rw )
{
OSG_NOTIFY( osg::ALWAYS ) Save testnode. std::endl;
osgDB::ReaderWriter::WriteResult wr = rw-writeNode( *test,
myOstream, new osgDB::Options(Ascii) );
if (wr.success() )
OSG_NOTIFY( osg::ALWAYS ) Save successful.
std::endl;
else
OSG_NOTIFY( osg::ALWAYS ) Save failed.
std::endl;
}
else
OSG_NOTIFY( osg::ALWAYS ) error getting readerWriter for
osgt std::endl;
myOstream.flush();
myOstream.close();
The outputfile contains:
Code:
#Ascii Scene
#Version 2
#Generator OpenSceneGraph 2.9.7
osg::Group {
UniqueID 1
}
The headerfile of the transport container is:
Code:
#pragma once
#include osg/Group
#include osg/Matrixd
#include dataIO_executer.h
#include dataIO_slotContainer.h
#include vector
class dataIO_transportContainer : public osg::Group
{
public:
dataIO_transportContainer(){}
virtual ~dataIO_transportContainer(){}
typedef std::vectorosg::ref_ptrdataIO_executer executerList;
typedef std::vectorosg::ref_ptrdataIO_slotContainer slotList;
private:
int frameID;
osg::Matrixd viewMatrix;
executerList executer;
slotList ioSlots;
// Access functions for Serializer
public:
int getFrameID() const {return frameID;}
void setFrameID(int frameID_ ){frameID=frameID_;}
void setViewMatrix(const osg::Matrixd
viewMatrix_){viewMatrix=viewMatrix_;}
const osg::Matrixd getViewMatrix() const {return viewMatrix;}
void setExecuter(const executerList executer_) {executer=executer_;}
const executerList getExecuter() const {return executer;}
void setIOSlots(const slotList ioSlots_) {ioSlots=ioSlots_;}
const slotList getIOSlots() const {return ioSlots;}
};
.. and the wrapper definition is:
Code:
#include dataIO_transportContainer.h
#include osgDB/ObjectWrapper
#include osgDB/InputStream
#include osgDB/OutputStream
REGISTER_OBJECT_WRAPPER( dataIO_transportContainer, // The
unique wrapper name
new dataIO_transportContainer, // The proto
dataIO_transportContainer, // The
class typename
osg::Object osg::Node
osg::Group std::dataIO_transportContainer ) // The inheritance relations
{
ADD_INT_SERIALIZER( FrameID, 0 );
ADD_MATRIXD_SERIALIZER( ViewMatrix, osg::Matrixd() );
ADD_LIST_SERIALIZER( Executer, dataIO_transportContainer::executerList
);
ADD_LIST_SERIALIZER( IOSlots, dataIO_transportContainer::slotList );
}
Why does serializer stop after defining the origin of this class? he onlsy
write down that this class is inherited from osg::Group.
Why does the serializer not dive into my class and serialzes all defined
elements?
Thank you for your help,
Torben

Re: [osg-users] [solved] How does ADD_LIST_SERIALIZER work?
Hi Wang, thank you for this introduction. Now I think I understand (at least a little) the design of the serializer, but I have a quite elementary problem: I don't wont to write my objects to file, I would like to get the bitstream to send it over network. My idea was something like a pointer to a buffer and size information how long the content is. This way I could read my serialized objects and pass the data to the cluster engine. How can I retireve the serialized data? Is it binary or a large ascii string? (because source and target of the compressor are std::string) Additionally I have a question regarding compressors. In the wiki page is noted, that zLib compressor is available. I found it in the source code, but how can I apply the compressor to the stream to get a smaller stream? I'm not sure to use it, but its an interesting option with that compressor..

Re: [osg-users] [vpb] VPB fails because build_master.source is empty
Hi,
I dived into the code and discovered, that the problem is cause by
vpbmaster.cpp:
Code:
if (!taskManager-hasTasks())
{
std::string sourceFileName = taskManager-getBuildName() +
std::string(_master.source);
tasksOutputFileName = taskManager-getBuildName() +
std::string(_master.tasks);
taskManager-setSourceFileName(sourceFileName);
if (!taskManager-generateTasksFromSource())
{
// nothing to do.
return 1;
}
taskManager-writeSource(sourceFileName);
...
The function taskManager-writeSource(sourceFileName) itself
calls
Code:
osgDB::writeNodeFile(*_terrainTile, _sourceFileName);
This last function call returns true ( for success) but it does not seem to be
successful.
If I'm right, the appropriate reader/writer is determinded by the extension.
But I can't discover which plugin is used to store a .source file.
Because this file is empty, the osgdem tasks fail and the program exit.
Can anyone give me an hint wich modul / class or filename handles writing
.source files?
my suggested solution:
Step 1: modify TaskManager to throw an exception if writing build_master.source
failes.
Step 2: determin the correct writer, fix him and ensure that he returns false
on failure.
Best regards,
Torben

[osg-users] [vpb] VPB fails because build_master.source is empty

[osg-users] Maybe Bug in Culling near in combination with HUD and negative values
Hi, Just for your interest, maybe it is not a bug: Yesterday I spent 4 hours to fix my ClampProjectionMatrixCallback for automatic near far computation. I combined it yesterday with an HUD (like osgHUD example) and discovered, that the culling crashes if the computation returns negative values for the near plane. In my callback, the near plane depends on the height above terrain (HAT). Because at the beginning of the program startup, this computation returns negative values. This causes the render process not to render properly. The framerate is very low and nothing is rendered except the broken HUD. It looks like an culling problem combined the wrong clearmask. Yes, I'm guilty because my callback produced negative values (of course I fixed it..), but maybe someone has a similar problem and this post can help :) I do not know if something should be changed, maybe the function which executes clampProjectionMatrixImplementation should clamp the values to valid values.

Re: [osg-users] [vpb] Are we too optimistic about large database generation ?
Hi Luc, I had problems like you, but I managed to discover a setup which works without problems, and renders large databases. At first: Are you really really sure you want to use windows? Don't misunderstand me, I'm not a linux-geek, I use myself windows for nearly everything, but VPB is one of the things which are running much faster on linux. I do not know why windows is slow an fails after some hours or days, but it seems to be related with NTFS, because rendering under linux with a NTFS partition is still slow and unstable - so only use native linux filesystems like ext3 or ext4. To reduce your rendering time, use a cluster with vpbmaster and use a 64 bit system (32 bit kubuntu fails in my during creating all the taskfiles - maybe running out of handles or things like that. In 64 bit, it works.) and now, if your process still fails after some days, just resume your compile process (only available in 2.9.6 and newest vpb) See also http://www.openscenegraph.org/projects/VirtualPlanetBuilder/wiki/Resume Now, if you have lots of CPUs and RAM, but your HHD is your bottleneck: Compress your textures lossless. This will shift your system load a little bit from HHD input to CPU, because your loaded sources are smaller but have to be decompressed in memory. In my case, the database rendering became much faster! If you have any questions, contact me.

Re: [osg-users] MultiTexturecontrol on OSG subgraphs (NOT VPB)
Hi Robert,
I understand the multitexturecontrol example, I modified it and slenderized it,
so that I simply can shift the textureWeight between my two examples.
But the output is not correct. I suppost my model is not correct textured.
therefore I need to know what a) the right structure is or b) what the reight
procedure is to generate the right structur.
Unfortunately the is no doc so I failed to learn it myself.
My startingpoint:
I have a model, which has a texture. Aditionally I have a not used 2nd
texturefile, which I'd like to ambed as second user, so I can switch between
texture1 und texture 1 ( day texture and night texture).
I load my model, and put it after an osgFX::MultiTextureControl node.
if i switch textureweight, it changes the look, the background behind the
texture changes, and if I focus totaly to the second texture, no texture is
visible.
what wiiould be the correct way to texturize my model.
Because one texturunit is in use, I suppose the textureVertices shouldn't be
any problem, because they exist already.
I simply want to change change the texture.
This was my code to add the 2nd texture:
Code:
bool airportCreator::addTexture( osg::Node* node_, std::string textureFile_,
int textureUnit_)
{
// check to see if we have a valid (non-NULL) node.
// if we do have a null node, return NULL.
if ( !node_)
{
return false;
}
osg::Geode* geode = getFirstGeode( node_ );
if (!geode)
return false;
osg::Texture2D* texNode = new osg::Texture2D;
// protect from being optimized away as static state:
texNode-setDataVariance(osg::Object::DYNAMIC);
// load an image by reading a file:
osg::Image* texImage = osgDB::readImageFile(textureFile_);
if (!texImage)
{
qDebug() Error couldn't find texture ' textureFile_.c_str()
', quiting.;
return false;
}
// Assign the image we read from file to the texture:
texNode-setImage(texImage);
// Assign texture Node to node.
//node_-getOrCreateStateSet()-setTextureAttributeAndModes( textureUnit_,
texNode, osg::StateAttribute::ON );
geode-getStateSet()-setTextureAttributeAndModes( textureUnit_, texNode,
osg::StateAttribute::ON );
return true;
}
Can you help me?
Thank you in advance,
Torben

Re: [osg-users] [vpb] Geocentric Database, how to flattening area or cut out piece
Hi, Well, now I don't understand the different between your loader/saver and your .modifyterrain and your pseudo loader/saver I suppose your what-elevation-should-I-put-here LOADER callback is for modifying terrain on the fly during visualization What ist your callback SAVER for?= creating terrain with VPB? I think the problem is divided in to seperate aspects: a) building an interface to OSG / VPB to modify terrain elevation b) more or less sophisticated algorithms to determine what the desired elevation of a specifiy coordinate should be ( maybe only lifting/sinking, mybe smoothing like osgTDS does) Is your available code now compatible with osg 2.9.5, oder is it any old styled (you mentioned something abould a code which hast to be adapted) The background of my project: I develope a visualization for flight simulators, focused on research simulators. I am allowed to publish the whole project as open source, so when I'm finished, i will post it as a new nodekit. The porject is different from flightgear, because it is focused on the aspects of a flightsimulator, not a game ( framerate,, lights must be specific, multichannel projection with softedge blending, HAT/HOT/Collision query interface,etc.etc.etc.) The data like airports and orthophoto is of course commercial und won't be posted in any way, but maybe screenshots... The terrain modification is requiered because the airports need to be settled at flat terrain. so my problem consist of two aspects; a) interface to osg/VPB to control elevation b) algorithm to determine my desired algorithm. Just setting the elevation to a constant value is NOT enough because surface is curved and would cause an elevation error of about 4m on a 10km long airport. Because my project is academic, I have no budget for developement work, but I would like to participate work packages to create an open source solution of my problem. If you introduce me in your solution of the elevation modifikation, I'll try to implement a solution for the question how height area must be.

Re: [osg-users] [vpb] Geocentric Database, how to flattening area or cut out piece
Hi, yes, a simple rectangular region would be enough. Does your algorithm determine the height of your flattend area itself by the selected area, or do you specify a destination height and you lift/sink your rectangular area to this level? I'm interested in both methods. Some models are always on, so in best case this flattening is compiled into DB to save rendering time. Additionally some models are inserted on demand on free coordinates, so this flattening would be great.. Is your feature closed source or is it planned to integrate it into VPB? Thank you very much!

Re: [osg-users] [vpb] lots of failed tasks: Resuming vpbmaster run
Hi Robert, at the moment I dont Use a Cluster, I would be happy if i could compile the large dateset one with the local 8 cores (I tried tu run it localle with 2 up to 8 cores) For smaller Datebases I used SSHFS as lightweight cluster filesystem, it worked great. Because running the osgdem tasks manually works great, I asume that vpbmaster uses a lot of any (at the moment) unknown ressources while building all task files. Therefore the osgdem process crashes if vpbmaster starts them. If could divide the taskfile creation from the osgdem calls, it should work. Because I move to another city, I cannot spend time into the project for the next two weeks, so I will resume this topics if I continue to work.

Re: [osg-users] [vpb] lots of failed tasks: Resuming vpbmaster run
Hi Robert, i've restartet the build process to get the error messages. For example: The logfile of the task contains: Code: 0.011: Adding terrainTile 0.339: DataSet::_run() 0 0 3.161: started DataSet::createDestination(13) 3.236: Time for after_reproject 0.074983 3.376: AR=2.00 C1=2 R1=1 3.376: createNewDestinationGraph 3.665: Time for _destinationGraph-computeMaximumSourceResolution() = 0.058913 3.665: Time for createDestinationGraph 0.288915 3.665: Time for after_computeNeighbours 0.52 3.665: completed DataSet::createDestination(13) 3.665: There are 1 contributing source files: 3.665: /mnt/disk3/bluemarble/B1.tif H no reason why it crashes, but it crashes. The corresponding /var/log/syslog: Code: Oct 5 17:18:57 visual-right kernel: [13260.734567] osgdem[7810]: segfault at 7fe06934 ip b51a6754 sp bfe068c0 error 6 in libxcb.so.1.1.0[b519d000+18000] Oct 5 17:18:58 visual-right kernel: [13261.066511] osgdem[7812]: segfault at 7f9e7d14 ip b5285754 sp bf9e7ca0 error 6 in libxcb.so.1.1.0[b527c000+18000] Any idea?

Re: [osg-users] [vpb] lots of failed tasks: Resuming vpbmaster run
Hi Robert, executing the taskfiles manually works without crash. If I would write a script which analyses all taskfiles regarding their pending status, and execute that taskfile if it's status is pending - would it result in a usable database? Because osgdem itselfs works properly I assume that the high system load of vpbmaster and all of that open files are the reason for the crash. Especially that several independet libraries crash intidates a problem in my configuration/systemload. For example I rised the ulimit of allowed open files to 50, but the problem of vpbmaster remains. Are there other limits/values (listable via ulimit -a) that could cause the problem? Thank you very much!

Re: [osg-users] [vpb] lots of failed tasks: Resuming vpbmaster run
Hi Robert, my diskdrive is mounted with default settings, which includes async. vpbmaster calls up to 250 Mb, seems to be OK. The usage of an osgdem call is not pssible, because ALL osgdem calls fails, so no one lives long enought to get his memory consumption. re-running vpbmaster with the corresponding build_master.source file makes no sense, because all tasks, even the completed, are reset to status pending. is is fixed in 0.9.11? I use 0.9.10 because 0.9.11 was not compileable on my kubuntu. I variied the number of processes from 1 up to 8 (one per CPU), but nothing changed. Would calling all task files manually result in a valid database?

Hello Robert, thank you for the introduction. I've postponed the scripting engine due to some other urgent aspectes, but I'll continue to try in some days. and will come back on this topic.

[osg-users] osgIntrospection / gen_wrapper - How to use ist?
Hi, I'm building an osg based visual system for simulators ( e.g. flight simulators). I want to use the osgLua Nodekit for scripting support and discovered that it is build on osgIntrospection. Now I'd like to know how to enable osgIntrospection for my own classes. I have read that modification of my osg classes are not requiered, because the osgIntrospection framework is able to do it automaticaly via gen_wrapper. Unfortunalety i've only found documantation for an old osg version here: http://www.openscenegraph.org/projects/osg/wiki/GenWrapper . What have I to do to make my osg (2.8.2) classes osgIntrospection ready? Thank you very much!

Re: [osg-users] near far plane
Hi,
I have the same problem and decided to choose the callback solution.
My callback calculates( so far) useable values for near and far plane, but this
values are completely ignored.
My current (maybe wrong ;) ) implementation is:
Code:
double cloudNear, cloudFar;
computeNearFarClouds(cloudNear, cloudFar);
if (cloudNear znear) znear = cloudNear;
if (cloudFar zfar) zfar = cloudFar;
if (zfar minFar) zfar = minFar;
bool ret =
stockCullVisitor-clampProjectionMatrixImplementation(projection, znear, zfar);
if (skyDrawable)
{
skyDrawable-setSkyboxSize(((zfar - znear) * 0.5 +
znear) * 2.0);
}
return ret;
I install my callback with
Code:
cb = new skySilverLining_projectionMatrixCallback( atmosphere,
viewer-getCamera(), sceneRoot);
viewer-getCamera()-setClampProjectionMatrixCallback(cb);
cb-setSkyDrawable(skyDrawable);
Now I question myself what I have to do in detail to use the callback.
I guess that the functions
Code:
clampProjectionMatrixImplementation(osg::Matrixf projection, double znear,
double zfar) const;
clampProjectionMatrixImplementation(osg::Matrixd projection, double znear,
double zfar) const;
are called by the callback mechanism, right?
What should I do with the three parameters? Is it sufficient to set the
variables znear and zfar, or do I have to perform any operations on the
projection variable?
I hope anyone can enlight my mind..
Thank you very much for your support,
Torben[/code]

Re: [osg-users] New way to workaround MSVC False Positives
Hi,
My Workaround bases also on MFC, but seems to smaller:
My standart project started as an empty console application without MFC.
If I enabled only the memory leak detection, i get lots of memory leak
notification because OSGS static objects are not clean until the end of the
applications leak detection.
My solution is:
1. enable the memory leak detection in the main function:
Code:
int main(int argc, char** argv)
{
/*// Redirect memory debugging output to console
_CrtSetReportMode( _CRT_WARN, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_WARN, _CRTDBG_FILE_STDOUT );
_CrtSetReportMode( _CRT_ERROR, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_ERROR, _CRTDBG_FILE_STDOUT );
_CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDOUT );
*/
//start memory observation
_CrtMemState s1;
_CrtMemCheckpoint( s1 );
{ // this scope is important!! It'ns nessecary to use OSG in a subscope
of the mainfunction to get no false memory leak indications,
// use an ArgumentParser object to manage the program arguments.
osg::ArgumentParser arguments(argc,argv);
// instantiate the applications main class
osg::ref_ptrapp_core core = new app_core(arguments);
// init app
core-initialize();
}
// check for leaks
_CrtMemDumpAllObjectsSince( s1 );
return 0;
}
2. To disable all false notification based on the static variable problem (e.g.
singletons):
Edit the MSVC Project:
-project settings: Use of the MFC library: change from USE WINDOWS STANDARD
LIBRARY to USE STATIC MFC LIBRARY
(The use of the dynamic MFC dll doesn't work.)
In my project, now all false positives disapper and only the (test) memory leak
remains.
Unfortunately memory leaks are not related to codefiles and codefiles, so
fixing is quite problematic. To solve this issue:
3. Enable Codefile and Codeline identification
Add a file memoryLeakDetection.h or something like this to your project.
this File contains:
Code:
#pragma once
#ifdef _DEBUG
#include crtdbg.h
#define DEBUG_NEW new(_NORMAL_BLOCK ,__FILE__, __LINE__)
#define new DEBUG_NEW
#else
#define DEBUG_NEW new
#endif
Incude this file in every .cpp file after your corresponding header File.
I included the file in the .cpp file to get rid of problems resulting from
multiple direct and indirect inclusion in the header file (pragma once doesn't
seem to work well in all situations.).
Now you should have only named, numbered and true memory leaks in your
application :) I hope this spares someone for searchong severals hours for a
solution as i did.
Cheers,
Torben
