Re: [osg-users] osgUtil::Simplifier in OpenSceneGraph 1.1 or 1.2 Version
Hi Sam, You can should be able to back port osgUtil::Simplifier to OSG 1.2. The other approach you could take is just port your app to OSG 2.8, as this will bring you plenty of other benefits besides the Simplifier. Robert.

Since the older version there was no support for the Simplifier option in OSG. Is it possible to integrate this option in older versions or no?. Please if you have any suggestion or answer or may be you already experience a problem like this let me know Thank you in advance.

Re: [osg-users] osgUtil::Simplifier in OpenSceneGraph 1.1 or 1.2 Version
Thank you Robert for the answer. But updating the osg version of the application(it's a huge application with too many classes and dependencies) may cause some problems. I don't know realy the real impact of a such update but i remember that i tried to update the old version to the new one and finelly somthing was wrong. Is there way to update the OSG without causing problems later. Thank you in advance.

Re: [osg-users] osgUtil::Simplifier in OpenSceneGraph 1.1 or 1.2 Version
I've migrated one small-medium project from 1.2 to 2.x and am preparing to migrate another really large project. The biggest issue is removing producer. If you don't do much with the internals of osgProducer::Viewer or Producer::Cameras then the upgrade should be pretty straight forward. If you do, then there is a bit of work to do. Another area that caused some pain was migrating our 1.x .ive files to 2.x. We use the .ive format exclusively for run time and distibution. The .ives are created from .flt files and the flt loader changed in 2.x. We found a couple differences in the loaders but were able to make changes on the .flt side. Just make sure you test the models extensively. Brian This is a PRIVATE message.

Thank you Brian. But once again if i tried to use osgUtil::Simplifier in osg1.2 what should i do to get the Simplifier options in my program without updating the OSG version Thank you in advance.

The code to the OSG is all open source, you can grab what you want and back port to your heart's content. Exactly how you want to go about it is your problem, it should be just basic C++ issues such as modifying project/makefiles and tweaking code where necessary. It might just be worth your while pulling down OSG-2.8 and learning about it. You can test the Simplifer in OSG-2.8 and see if it suits your needs. You can also look the task o porting at the same-time, it needn't be a huge task if you application code was well written as the majority of the OSG API is very similar between 1.x and 2.x, the main difference is the viewer code.

Re: [osg-users] osgUtil::Simplifier in OpenSceneGraph 1.1 or 1.2 Version
Sam, Robert suggested back porting the osgUtil::Simplifier class. Grab those files and add them to your 1.x distribution. Brian This is a PRIVATE message.
