[osg-users] [osgOcean] When build new project, can not open osgOceanD.lib
Hi,
I'm a chinese student. I have complied the osgOcean successfully. I can run the
oceanExample, and do everything in its applicantion.cpp. But now, I meet a
problem: If I make a new project, when run the code, it alway declare an error:
LINK : fatal error LNK1181: 无法打开输入文件“..\..\lib\Debug\osgOceanD.lib”,
(Cannot open the input file:osgOceanD.lib)
My osgOceanD.lib is located in F:\OSG\osgOcean\build\lib\Debug, and I also add
this path to TOOLS—Option —Directories- Library Files. In the Windows
PATH, I add F:\OSG\osgOcean\build\bin\Debug.
So, I need to know how to solve this problem.
Thank you!
Cheers,
Han
Following is the test code:
#include osgViewer/Viewer
#include osgDB/ReadFile
#include osgGA/TrackballManipulator
#include osgOcean/OceanScene
#include osgOcean/FFTOceanSurface
int main()
{
osg::ref_ptrosgViewer::Viewer viewer =new osgViewer::Viewer;
viewer-setUpViewInWindow(150,150,1024,768,0);//setUpViewInWindow(150,150,1024,768,0);

viewer-addEventHandler(oceanSurface-getEventHandler());
viewer-addEventHandler(oceanSurface-getEventHandler());
osgGA::TrackballManipulator *tb = new osgGA::TrackballManipulator;
tb-setHomePosition(osg::Vec3f(0.0,0.0f,20.0),osg::Vec3f(0.0f,20.0f,20.0f),osg::Vec3f(0,0,1));
viewer-setCameraManipulator(tb);
viewer-setSceneData(oceanSurface);
viewer-run();
return 0;
}
This code is ok when copy to applicantion.cpp, but can't be use in new any
projects.

Hi, I want to use the mouse to create a rectangle on the X-Z plane(Y=0). Like 3DsMax, when I push the mouse, it decide a corner of the rectangle, and then drag the mouse, finally release the mouse. However, the main problem is how can I know the the world coords on the X-Z plane (Y=0) of point when I click the mouse on the view(I only can know the screen coords X,Y). I have a idea, but I want to have a better one. First, create a infiniteplane on the X-Z plane(Y=0). Second, use view-computeIntersections(x,y,intersections) to get the wold coords of the intersection point. This solution is complex because I must create a infiniteplane.

Re: [osg-users] [build] OSX build (not Xcode)
Thanks for info. It would be nice if the build system was updated so that it would test lipo on libraries before using them in the project. 32bit libraries are not uncommon at least on our Macs, so we have to do a lot of hiding of libraries to get OSG to build since cmake will happily point to incompatible 32bit libraries. Nevertheless, we did that and the build works, however, the ffmpeg plugin requires the linker flags that for some reason cmake is not adding, so I have to add them manually to the link.txt file (don't know how to add them in cmake). -lmp3lame -lx264 -lbz2 -lfaad -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47025#47025 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] why point disappeard ?
Hi,
I'm developing a 2D drawing tools , which could draw lines with mouse now. but
I encountered a problem , if want to draw a point , I had to draw two , or draw
another object together , or the first point will not show .
the code is in Line.cpp Line：198 as follows:
Code:
void Line::drawAssistantPoints()
{
char name[30];
for( int i=0 ; i3 ; i++ )
{
sprintf( name , vertex_%d_%s , i , _name.c_str());
_assistantPoints[i]-addDrawable( drawPoint((*_vertexesArray)[i]));
_assistantPoints[i]-addDrawable( drawPoint( (*_vertexesArray)[(i+1)%3]
) );
_assistantPoints[i]-setName(name);
_group-addChild(_assistantPoints[i]);
}
}
'_vertexesArray' store the vertexes and middle point of the line .
the attachment is the code.
Now it could runs fine .
Its functions ： first click with the mouse in blank space to choose a point
, second click the get the second point and configure the line . Lines will be
focusd if clicked with its vertexs and middle point lighting .
Please anyone help me to find why the point disappeard ?
Thank you!

[osg-users] [build] Problems with OSG 3.0.1, Qt 4.8.0, mingw 64-bit
Hello everyone,
I am trying to use OSG 3.0.1 with Qt 4.8.0, with the mingw 64-bit compiler on
Win7 Pro.
So far, I have successfully set up a 64-bit build environment (in C:\mingw64)
and built the Qt libraries. All the Qt examples work, and I’m able to create
new Qt programs quickly and easily.
Next, I downloaded OSG 3.0.1 and built it, using CMake. The osgviewerQt example
program compiled and ran fine, so I thought I was ready to start writing
programs that use OSG and Qt together. This is when the strangeness started.
As a first test, I tried reproducing the osgviewerQt example program myself
using Qt Creator. I created a new Qt Widget app, and copy pasted code from
the osgviewerQt example. After setting up the .pro file, to link with the
required OSG DLL files, the application built without any errors. However, it
did not run.
I ran my test program in a debugger, and here is the backtrace:
First chance exception 0xC005 ACCESS_VIOLATION occurred at
0x00782803, read of address 0x at 0x00782803
(in C:\Users\Markus\Desktop\OSG examples\libosgd.dll)

0x6AE05B7F _ZN9osgViewer15CompositeViewer15constructorInitEv + 0x117 in
libosgViewerd.dll
0x6AE015D1 _ZN9osgViewer15CompositeViewerC2Ev + 0x191 in
libosgViewerd.dll

0x00401615 OsgQtTest02.exe
0x004013CE OsgQtTest02.exe
0x004014E8 OsgQtTest02.exe
0x7675652D BaseThreadInitThunk + 0xD in kernel32.dll
0x76CEC521 RtlUserThreadStart + 0x21 in ntdll.dll
(My test program is called OsgQtTest02.exe)
I can reproduce this behaviour easily, just by deriving a class from QWidget
and osgViewer::CompositeViewer, and then creating an instance of it in
main.cpp, like this:
#include QtGui/QApplication
#include viewwidget.h
#include iostream
int main(int argc, char *argv[])
{
std::cout Program starting std::endl;
QApplication a(argc, argv);
ViewWidget w;
std::cout Widget created std::endl;
w.show();
return a.exec();
}
This is the declaration of the ViewWidget class:
#include QtGui/QWidget
#include osgViewer/CompositeViewer
class ViewWidget : public QWidget, public osgViewer::CompositeViewer
{
//Q_OBJECT
public:
ViewWidget(QWidget *parent = 0);
~ViewWidget();
};
The message Program starting will appear, but Widget created will not,
because the app will crash when the ViewWidget instance is created. The
presence of Q_OBJECT seems to make no difference.
This has the feeling of a C++ ABI incompatibility, as if the C++ OSG DLLs were
built with a different C++ compiler. However I know that this is not the case,
because I built everything myself, with the same C++ compiler (except Qt
Creator itself of course).
I have tried rebuilding Qt and OSG a few times over the weekend, and I have
been over the CMake setup until the wee hours at night. I don’t seem to be
missing anything obvious. With Dependency Walker, I can verify that my app is
properly linked to the OSG and Qt DLLs.
I am at my wits’ end...
Does anybody have any advice on how to fix this problem?
Many thanks in advance,
Markus Svilans

[osg-users] Writing to OSG files, this might seem like an obvious question but...
Greetings all This is going to seem like a depressingly obvious question, I'm sure, but for the life of me I've run out of ideas. I'm poking around with OSG on a windows 7 64 bit machine, familiarizing myself with it. I have gotten through the points of compiling the source using first CMake and then Visual studio to build it. I have then found a group of example .osg files from somewhere on the wiki (I can find it again if relevant) and they will run and render fine. Basically up to step 4 of the getting started wiki page (sorry, I cant link it for the moment :C) Obviously, the viewer runs .org files. However, I am at this point getting dirty with the c++ files, which is fine, but wont be for long. There is a big looming question that I cannot for the life of me find an answer to. How does a .cpp file end up as a .osg file, or elsewise in some way end up going from source code to being a rendered object on my screen? I cant find any information on this, except for one line in the sticky at the top of this forum, cryptically telling me that it might be useful to write your ccp files to OSG files for debugging purposes, with no reference of how to do this. Can anyone enlighten me, or at least throw a link or two my way?

Hi all,
Thanks for all the feedback.
In case you are interested, I have made a patch for the OpenFlight plugin so
that it reades/writes the surface material code (SMC) and feature id (FID)
and stores it as a description of the geode that contains these attributes.
The format of the description string is like SF:[SMC]:[FID] for example
SF:918:10
So you can expect to see in the .osg file something like this:
Code:
Geode {
DataVariance STATIC
...
description SF:918:10
...
}

[osg-users] create OpenThreads threads dynamically rather than before the viewer runs?
Hi all, First off, I am both an OSG and multithreading newb so I apologize if I am fundamentally off. Following the OSG Beginner's book, I am able to successfully start threads before the viewer runs using OpenThreads. My question is: is it possible to create threads dynamically, only when a user requires it, or must they always be created before the viewer runs? If you require more background, I have created a GUI with the FLTK library and am using OSG to render the scene. I want to be able to connect to a given sensor by hitting a GUI button in order to get live data. The problem is it takes a while to connect to a given sensor and my UI freezes. As stated above, if I spawn the thread before the viewer runs then everything is fine. I have tried spawning threads following the button press, but it does not work as my UI freezes. Any assistance or pointers would be most appreciated. Thank you!

The solution, I believe, is to check that the thread is done before calling cancel. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47187#47187 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] create OpenThreads threads dynamically rather than before the viewer runs?
Confirmed. Please mark as solved or remove topic.
For what it's worth, my solution:
_sensorHandler.startThread();
if (!_sensorHandler.connect(host))
{
return false;
}
_sensorHandler.cancel();

Re: [osg-users] create OpenThreads threads dynamically rather than before the viewer runs?
Hi again,
I have another problem along the same vein so I don't think I should create a
new topic though feel free to correct me if I am wrong:
How can I deactivate my GUI button while the sensor attempts to connect and
re-active the button only if the connection attempt has failed and been aborted?
Here's what I tried unsuccessfully in the callback for the connect button (the
following code is fltk but should be applicable to any GUI library):
Code:
_connectButton-deactivate();
if(_scene-connectSensor())
{
_disconnectButton-activate();
}
else
{
_connectButton-activate();
}
The problem is _scene-connectSensor() is running in a thread, so the main
thread sees false for the return of connectSensor() and re-activates the
connectButton.
Note that _scene inherits from osgViewer::CompositeViewer and Fl_Gl_Window. I
have already tried making it inherit from OpenThreads::Thread but when I try to
re-implement the run() method, I get a conflict between CompositeViewer::run()
and Thread::run(). I have thought about having my GUI poll the state of the
sensor's connection to check if it has finished, but I'd like to know if there
is a more elegant solution that escapes me.
As always, any assistance would be much appreciated.
Thanks!
Andrew[/code]

Re: [osg-users] create OpenThreads threads dynamically rather than before the viewer runs?
Yes, I'm making it a bad habit of talking to myself. For what it's worth, I have managed to get it working using a fltk gui timeout callback. I'm starting to think there is no other option. So for those interested, in my connect button callback, I added Fl::add_timeout(1,(Fl_Timeout_Handler)pollSensorConnectionStatus); which calls pollSensorConnectionStatus every second. Other relevant functions of interest are repeat_timeout() and remove_timeout(). See fltk sample code blocks.cxx for a working example.

[osg-users] OSG Reference Manual Doxyfile
Hello, This isn't so much an OSG question as it is a Doxygen question. The OSG reference manual is created using Doxygen, and I am also using Doxygen to create a reference manual of my own on a different project. However, the basic configuration file isn't as neat as the one OSG apparently uses. Does anyone know where I can find the most current Doxygen config file that the OSG reference manual uses?

Re: [osg-users] Robert Osfield robert.osfi...@gmail.com, Building new website, assistance appreciated!
Hi Diane, There exists work in progress at http://openscenegraph.com . The development is in the first stage and help is appreciated. We discussed about which framework to use, but at the end robert felts that WP is not enough for the openscenegraph website needings. You say Joomla and drupal are hard and not user friendly, do you mean for the front-end and author users or for the admin tasks? Cheers. 2012/4/12 Diane Potter di...@springboarddesigns.com Hi Tom and Robert, I'd try to stay clear of Drupal or Joomla, both are ridiculously hard and not user friendly. I'm a web developer and we use wordpress to build our sites. You can either user wordpress dotcom (a hosted version, but not as flexible) or use what most people are using now, wordpress dotorg. You can usually install this from your server using Fantastic or Site Software very easily. I think in the end of you choose Wordpress you'll be much happier. WP has many free and premium plugins that can be used to enhance your site and make it do what you need it to. Anyway, if you get stuck and need some help you can let me know. ... Thank you!

[osg-users] [build] x86_64, cmd line, built OK - but warning in Xcode
Hi,
I've successfully compiled trunk using cmake on 10.7.3. That's with Apple LLVM
3.0.0. No additional CXX flags passed into make.
With the implicit conversion to 32bit type enabled, I am seeing warnings to
do with precision loss. e.g:
In file included from
../iShowU-v3/Frameworks/OpenSceneGraph-3.1.3/Debug/osg.framework/Headers/StateAttribute:20:
...
...
../Frameworks/OpenSceneGraph-3.1.3/Debug/osg.framework/Headers/Shader:56:47:{56:47-56:59}{56:40-56:46}:
warning: implicit conversion loses integer precision: 'size_type' (aka
'unsigned long') to 'unsigned int' [-Wshorten-64-to-32,3]
unsigned int getSize() const { return _data.size(); }
~~ ^~~~
Couldn't get the formatting to work, but the ^ char is pointing at the _data
term, just after return.
Is this something I need to be worried about? Is it safe for me to switch the
warning off?
After looking - this warning appears to be disabled in my other projects - but
it did get me a little concerned - so here I am, asking the Q. :)
Thank you!
Neil

Having just upgraded to 4.3.1 myself, I can confirm that: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer does the trick. I didn't install any newer version of cmake.
