Re: [osg-users] API changelog for OSG3
Hi Ehsan, For the most part the common API of 2.8.x and 3.0.x has been maintained so applications should port from 2.8.x to 3.0.x easily. Often it will simply be a case of recompiling against the new version, occasionally you might find a difference, if you do just ping the list or have a look through the API in question, if there has been a change that effects you it's very likely it's something like typo fix or minor revision. The big differences between 2.8.x and 3.0.x lie in internals of the OSG, and additional new functionality that sits alongside the old classes. The really big change is that the OSG now supports OpenGL ES, but for an OpenGL/OSG application developer this will just be latent functionality that you won't use and won't be affected by. Robert.

It seems I should be able to start with 3.0 but then I wonder why 2.8 is still popular. Specially I noticed alphapixel kindly provides desktop binaries, that also includes the rather old 2.8.5. Is there any major leap that has made 3.0 dramatically different? Thank you!

In my experience providing OSG consulting and dev services, some of my customers are content with the stability of 2.8.5 (June 2011), and have no particular need for the features in OSG 3.0.1 (July 2011 -- so 2.8.5 is really not that much older per se). Of my customers who *have* moved to 3.0.1, none are making extensive use of the big new features as far as I know. The big features that I recall are: - OpenGL ES support - OpenGL 3 support - New native file format - Performance enhancements for DBPager I know there are many people on the list who are using these features. Whether you have a need to move to 3.0.1 or not is entirely up to you and your needs. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] API changelog for OSG3
Paul and Robert, Thank you that is exactly the information I was looking for, and for the reference both 2.8.5 and 3.0.1 linked fine and so far I do not see any issues. Well, even 2.8.2 was working great, OSG is an excellent software. I guess I will update to 2.8.5, and then to 3.0.1 later after doing some more tests. Thank you for this great software!

Re: [osg-users] API changelog for OSG3
I'd wait until the next stable release before going with 3. There's several bugs in the 2.9.x/ 3 releases that have been resolved. Such as incorrect text rendering, buggy slow path rendering and some sort of GL resource handling bug that was causing reuse of invalid display lists. These have all been fixed in the 3.1.x branch.
