Hi Robert, I understand your opinion, but respectfully disagree. This test has been working just fine for over 20 years. This is not something made up last night. > There are people out their struggling for physical and mental health, > or have loved ones who they have lost or struggling. This test has nothing to do with that, but when we met in Virginia, you told me about what your family went through, so I do understand why you might bring this up and your reaction. My family has members who have intellectual disabilities, and members who work with disabled children, and are BCBAs by trade. So we are all psychology educated. I respect all freedom of expression and freedom of choice, so if you don't want PR submissions from me to help out the project, that is completely understandable.

It is the "modern" one since it will never be updated. It does not give you anything past OpenGL1.1 i think. With my fix, users would still need to manually use the Open GL extension functions to access all the latest functionality as they do now, but they wont have to manually configure cmake. My fix is only a cmake fix, not an OSG functionality fix. It lets the user define OPENGL_PROFILE before pressing "Configure" in windows cmake and automatically sets up the disabling of deprecated functions in OSG. Without it you have to know and manually select what you think should not be in the GL3 profile. Robert already has that defined in CMake, in windows it is just never called unless you have the old gl3.h header...which no one does anymore. So this is more of an update. I'll make a pull request, and let Robert look at it...

Re: [osg-users] GL3 Profile
Hi Maxim / Robert, I am using GL3 on Windows. I had to download and slightly modify the Khronos glcorearb.h file, to get it working right with the declspec or dllimport or whatever it was. It was not trivial or obvious by any means. But it works now, after supplying that file. I understand where you're coming from Maxim, but one thing I don't get: >> So the fix I can make is change the CMake script to use the modern default >> windows GL headers which will enable people to use the GL3 profile option, >> and configure cmake to disable everything that needs to be turned off in >> that case. What and where is the "modern default windows GL headers" ? I have the Windows Kit 8.1 installed currently. That's where my implementation is finding gl/GL.h. It has no glcorearb.h that I can find, and its GL.h is only defined up to OpenGL 1.1. Can you explain where the headers are that you're referring to? I too would like it if Windows just worked better. But without the OS having a reasonable way to update the headers, I thought we were pretty much stuck with manually configuring OSG on the command line. - Dan > -Original Message- > From: osg-users [mailto:osg-users-boun...@lists.openscenegraph.org] On > Behalf Of Robert Osfield > Sent: Tuesday, June 26, 2018 11:42 AM > To: OpenSceneGraph Users > Subject: Re: [osg-users] GL3 Profile > > Hi Maxim, > > On Tue, 26 Jun 2018 at 14:59, Maxim Stere wrote: > > We don't want to do anything like GL3_WINDOWS since most likely that will > have to have a new external dependency. > > ??

It might not be working for YOU, with you particular preference for/against certain things, but I'm pretty sure that there are other Windows users using GL3 without any issues.

Re: [osg-users] GL3 Profile
Hi Robert, That is correct, I want to do a fallback. We don't want to do anything like GL3_WINDOWS since most likely that will have to have a new external dependency. But if we make the GL3 profile fall back on what already is there, it might be missing a few functions that the user will have to link to manually in the windows environment, but at least the context version will be correct, and the deprecated functions will be gone. Right now GL3 selection and auto configuration does not work on windows at all...

I can make a PR if that makes sense. As far as I'm aware VS just installs ancient GL headers, are you just suggestion that you want to combine the OSG's fallbacks for these ancient headers but with the OSG selecting just the GL3 code paths. Are you suggestion another OPENGL_PROFILE path? Something like GL3_WINDOWS? We can't break what is there already so if you want to do something different then it has to be "yet another workaround for the mess of different combinations of what should be standard".

Re: [osg-users] GL3 Profile
Hi Robert, It does not work like that on windows. Windows by default does not come with gl3.h or GLcorearb.h and neither does Visual Studio, so you need to install extra dependencies to make the OSG GL3 or GLCORE profiles to work. Otherwise you get errors when you select them as an option and try to build. This prevents people from using the GL3 profile and GL3 graphics context because OSG will create and report a lower context version. Also if they want to have no older functions and turn off the fixed function pipeline they now have to do it manually through multiple cmake options instead of just defining OPENGL_PROFILE to GL3. So the fix I can make is change the CMake script to use the modern default windows GL headers which will enable people to use the GL3 profile option, and configure cmake to disable everything that needs to be turned off in that case. I can make a PR if that makes sense.

You only get an error if you mismatch the CMake settings to the the headers you have, these OPENGL_PROFILE is meant to help select the appropriate headers. If you have gl3 headers (which are the old ones) installed and try to use GLCORE then you should expect problems, and have the modern GLcorearb.h installed and select GL3 then you'll get problems. So I don't think it's a case of "fixing" things for Windows. Just not misusing it.

This isn't a bug, just an awkward/inconstent way that GL3 is exposed across platforms, so we've had to have GL3 and GLCORE variants to attempt to cope with this. Within Cmake you can adjust the settings yourself, the OPENGL_PROFILE are there to just provide defaults - best guesses as to what you might need. > 2) When I do have GL3 profile enabled on windows, CMake turns off the fixed > function pipeline and a few other deprecated functionalities.

Are they just not converted to using newer GL > functionality? This is normal. OpenGL core profile deliberatly drops all backwards compatibility. OpenGL provides now mapping from fixed function pipeline to shaders for us so to do this requires the whole fixed function pipeline state to have a mapping matained by the OSG, this is huge task so not something we can easily add. Unless you need to run on MacOS with it's restrictions on exposing modern GL features to just GLcore profile I would not recommend building against GLcore profile, the whole deprecation strategy for OpenGL has ended up a bit of mess and has caused more problems that it solved. Outside of MacOS all the other desktop platforms still fully support GL2 and with the advanced features all accessible via extentions - the OSG will automatically set these all up for you. So you can best of both worlds, continence of having fixed function still work plus all the new features working as well.

[osg-users] GL3 Profile
Hi, 1) I've been playing around with GL3 and CORE profiles on windows, and noticed that for CORE, the CMake script makes VS look for GL/glcorearb.h and for GL3 profile it makes VS look for GL3/gl3.h neither of which are present on windows or VS. Just taking the glcorearb.h from the cronos page and placing it in the GL folder leads to other missing libraries. Is this a bug? If I change the CMake script to just look for the standard gl/GL.h on windows, everything compiles and builds. If that is how it should be, I can submit a fix for this, so that if set, GL3 profile would not create errors in the build, using only gl/GL.h and still turning off all the deprecated functions. Getting CORE to work is a bit more workbut at least GL3 will work... 2) When I do have GL3 profile enabled on windows, CMake turns off the fixed function pipeline and a few other deprecated functionalities. After I build OSG with this, most of the examples stop running correctly. I see a lot of GL errors and warning about things missing. Is this a normal thing? Are they just not converted to using newer GL functionality?
