Hello Abhinav,

There is nothing for anyone to go on to even try to help you. The code
snippet is not even osg code so no chance for us to know anything
about what it does.

* use a debugger to see what readAll returns and why
* crank up OSG_NOTIFY_LEVEL
* see Paul Martz top 10 debugging tips at

Re: [osg-users] [build] iv file not being read

2009-05-15 Thread Tomlinson, Gordon

Did you build or install one of the required 3rd Part libraries fro the
Inventor plug-in ?
( see OSG281\src\osgPlugins\Inventor\README.txt)

Also did increase the OSG Notify level to debug to see what OSG may be
telling you about the issue ?

And the other normal debug technique did you step in to the OSG code to
see where its failing on the read ?

Re: [osg-users] [build] iv file not being read

2009-05-15 Thread Jean-Sébastien Guay


Hi Abhinav,


i am trying to read an iv file but its not being read. the code i am using is :
***
 SoInput sceneInput;
if ( !sceneInput.openFile( plugins\\graphs\\myInventor.iv ) ) {
QMessageBox::information(mInventorGrid[3], Error, Cannot open file 
requested iv file);
return;
}

SoSeparator *sc_root = SoDB::readAll( sceneInput );
   sc_root-ref();

 Use one of the convenient SoQt viewer classes.
mViewer = new SoQtExaminerViewer(iv_widget);
mViewer-setSceneGraph(sc_root);
mViewer-setDecoration(false);
mViewer-show();
***


That's OpenInventor (and some Qt) code. Are you using OSG or 
OpenInventor? This is an OSG mailing list, and though OSG has an .iv 
loader, we can't help you debug OpenInventor code. Please go to the 
appropriate forum/mailing list for that.

Re: [osg-users] [build] iv file not being read

2009-05-15 Thread Gordon Tomlinson

1st Question is

Did you build one of the required 3rparty libraries you need for the
inventor plugin ?

See OpenSceneGraph\src\osgPlugins\Inventor\README.txt



2nd Question is did you turn up the Notify Level to see what why it may be
failing or did you step into the code to see why its failing ?
