The longer I think of it the more I agree with your earlier post. I realized we could start such extension cleanning but only if OSG had defined bottom line requiremnt for OGL version. As long as its not clealy defined, such clean up practice may be more problematic than frutiful.

Nothing against the proposal, simplification and clean up is good ... I just know I fall into the situation where large groups of my end users will be on what we thinks of as very old cards ( and where they cannot update or update easily ) and my paranoia then takes me down the road of oh heck.... :) Gordon Tomlinson Product Manager 3d Technology & Future Products Overwatch® An Operating Unit of Textron Systems ------------------------------------------------------------------------------ From: [email protected] [mailto:[email protected]] On Behalf Of Wojciech Lewandowski Sent: Monday, February 01, 2010 10:24 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Lets slowly update extension gl symbolstolatestOpenGL specification with each submission. Hi Gordon, What about when I'm on a machine and graphics card that only supports say OpenGL 2.1, I guess this is an argument for reverse approach ie to use common denominator and use extension versions in their earliest forms.... It is a valid point, I must admit I have not thought about it. Maybe chnging _EXT, _ARB to non suffix versions is not such a good idea after all. Maybe it was too early to come up with this proposal...

Would these only be obsolete if your using Opengl 3.2 ? What about when I'm on a machine and graphics card that only supports say OpenGL 2.1, this is a very common case for us were users are in very controlled environments and running on older equipment that is unlikely to get upgraded or new drivers etc. Gordon Tomlinson Product Manager 3d Technology & Future Products Overwatch® An Operating Unit of Textron Systems ---------------------------------------------------------------------------- From: [email protected] [mailto:[email protected]] On Behalf Of Wojciech Lewandowski Sent: Monday, February 01, 2010 6:24 AM To: [email protected] Subject: [osg-users] Lets slowly update extension gl symbols to latestOpenGL specification with each submission. Hi Everyone, Lots of older OpenGL extensions are now included in OpenGL specification (rel. 3.2). I'd like to propose a small cleaning movement of OSG sources Every time we submit a change of some OSG file we could also check for obsolete GL extension: EXT, ARB, NV, ATI etc symbols and replace them with most current OpenGL names. Idea is to take it easy and slow. Lets change only these header and source files which would get submitted anyways. Changing and submitting all OSG source at once could easily swamp Robert.
