Hello, I checked the installation of osg. I was not mixing debug and release. But to be sure I uninstalled debug. However I still have the same probem as before. I copied the stack trace if it helps. Do you have any idea ? osg65-osg.dll!100042aa() [Les frames ci-dessous

[osg-users] How to delete osg graphs properly?

Hi all, It's me again, with another practical problem : how to delete properly my osg objects when they contain lots of stuff? Basically I have a PAT with lots of groups and nodes inside it. At some point I need to delete it, then reinstanciate it right away. But I found out that doing this pro

Re: [osg-users] How to delete osg graphs properly?

Hi, hold your osg nodes (or the root node of your complete scenegraph) with osg reference pointer (osg::ref) instead standard pointers. Assign NULL to this pointer, than the ref pointer doesn't point any longer the node, and the node will be destroyed - unless you point with other pointers to t

Re: [osg-users] How to delete osg graphs properly?

Hello Ku, In addition to Torben's answer, which was good, I'll add this: My object is in an osg::ref_ptr, so I tried to .release() it first, it didn't quite change anything... Actually it did: that's what introduced your large memory leak. ref_ptr::release() tells that ref_ptr to stop manag

Re: [osg-users] Development Environment

Hi Guys, FYI: Yesterday I tried to build OSG with 2010. Last stable CMake 2.8.1 is generating some cryptic errors so I checked most recent CMake 2.9.x from nightly builds. That version seems to work, so if you want to work with OSG under VS 2010 try nightly builds CMake version. Cheers, Wojt

[osg-users] Recurrent warning on SVN trunk

Re: [osg-users] Recurrent warning on SVN trunk

HI JS, The void objectDeleted(void*) method is inherited from osg::Observer, so it's odd that the compiler would complain that it's unreferenced. Perhaps VS2008 requires this templated implementation to be declared virtual as well. Could you try changing: template struct WeakReference : public O

Hi Oliver, Sorry to hear it wasn’t as simple... It could be a bug, but normally someone else would 'pipe up' and say that was fixed :) Does look like a problem with pickhandler, can you post some source code to recreate the problem? Have you tried the examples and do the work ok? Also you may w

Hi Robert, Anyways, any other things you want me to try? Afraid not. We could just use a pragma to ignore it, but I'd rather get to the bottom of it and address it directly. OK, then anyone else have any ideas of what we could try? Anyone else had this warning in the past, and what did you

Hi Jean Sebastien, I have removed the warning by putting the declaration of objectDeleted() directly into the class definition. See attached file. It seems to be a compiler bug. I love template :) Fabien -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-u
