[osg-users] OsgAnimation Wrapper doesn't compile
Hello, This morning I've done a "svn up" and tried to compile osg under Ubuntu 9.04 All worked well until osgAnimation wrapper. This wrapper looks for Skinning header. I've seen that "Skinning" is obsolete, replaced by "RigTransformSoftware", but in osgWrapper/osgAnimation directory there is a file named Skinning.cpp. I think osgAnimation wrapper is not up to date.

Re: [osg-users] osgEarth seg fault in libosg
Hi Jason, A run with gdb and osg in debug mode and I've found the trouble : bad characters in xml .earth file.

Re: [osg-users] osgEarth seg fault in libosg
Hi Jan,
Thanks for your answer. Unfortunately, it doesn't work for me. I've got the
same error
I will try to compile osg and osgEarth in debug mode in order to have more clues

Johan

Re: [osg-users] osgviewerQT, qt4.4.0 and .osg file
Hi Norman, Thanks for the link. With GDAL way, no need for controlling the output, it's during the reading phase that conversion in done To resume : 1- searching local decimal separator 2- replace separator character into input string 3- convert string using standard method (atof for example) Step 1 could be done at initialization time. Steps 2 and 3 should be done each reading. The overhead is only step 2, as step 3 must be and is already called. As far as I known, only osgDB::Field should be changed, for getFloat and calculateFieldType methods. With only this, reading an osg file will work regardless of locale. Robert and others : I'm right ? Do you think it worth the effort ? Forgot something ? Johan.

Re: [osg-users] osgviewerQT, qt4.4.0 and .osg file
Hi Robert, Bingo ! I've modified Geometry.cpp to print out vertices before and after modification by osg::Field::getFloat and the result is a troncation of the float, only integer part is interpreted. You're right. What is the complexity of coding custom atof ? Is the hypothesis that '.' is a separator ? It means also controling osg output to write a '.' instead of ','. Or do you prefer that osg file can be with a ',' or a '.' as integer/decimal separator ? In first, I will see how to force QT local to C. But if I it is not to heavy to do custom atof, I'll try to do it as I think this way is better. Thanks a lot. Johan. Robert Osfield a écrit : Hi John, Great, a pictures saves a thousand words! The problem looks the same as others have encountered when WxWidgets modifies the C local such that atof switches from treating . and , as decimal points. My guess the later version of Qt is doing the same. We've tried several different attempts in the past to insulate the OSG from this change in local but weren't able to come up with a workable solution. The conclusion back then was that we might would need to use a custom atof method, this hasn't been developed yet though. Robert.
