Re: [osg-users] glsl version 130 not supported (and related problems)
Hi, did you solve your issue? In case you are using osgViewer's GraphicsWindowCocoa class there has once been a change in OSG: it explicitely specifies the OpenGL core version 4.1. If you specify the legacy version you should be fine. You can find the line for patching in osgViewer::GraphicsWindowCocoa::realizeImplemenation() (last OpenGL profile attribute).

Re: [osg-users] glsl version 130 not supported (and related problems)
Well I did some more research, and once again tried to tackled this problem. If someone has already tried to use the current master branch on OSX 10.12, could maybe give me some more in I am using Qt 5.7 by the way. This is what I tried so far: Clone current master (which has, I think, the VAO branch merge onto it). On CMake selected OPENGL_PROFILE=GLCORE. Deactivated GL1 and GL2 support, activated GL3 support,and *deactivated* : OSG_GL_FIXED_FUNCTION_AVAILABLE OSG_GL_DISPLAYLISTS__AVAILABLE OSG_GL_VERTEX_FUNCS_AVAILABLE Compiled and installed, everything went smoothly. Then in my app, I have to request a Core Profile. I am doing so using Qt's QSurfaceFormat::setDefaultFormat() so request a OpenGL 3.2 Core Profile. Also, in my OSG code, before I instantiate an osgViewer::Viewer, I use (as Robert suggested) osg::DisplaySettings::instance()->setVertexBufferHint(osg:: DisplaySettings::VERTEX_ARRAY_OBJECT); and this effectively makes OSG print a message indicating it is requesting the usage of VAO objects. Now, with this setup, nothing is rendered on the screen, and I get lots of shader compilation errors (These come from Qt). If I DON'T asctivate the Core profile using the Qt API, These errsod o not appear, but when I try to render a point cloud in a PagedLOD node, only white points start to appear and after some LOD's are loaded the app crashes. 2016-11-13 15:21 GMT+00:00 Robert Osfield : > On 12 November 2016 at 22:24, Bruno Oliveira > wrote: > > I was now trying to solve this and searched for OSX VAO related posts, > but > > could not find relevant instructions on how to compile for OpenGL Core > > Profile under OSX.

Hello, I was now trying to solve this and searched for OSX VAO related posts, but could not find relevant instructions on how to compile for OpenGL Core Profile under OSX.

When I shortly after I first announced the vertex_array_object branch I asked for feedback on OSX GL3 core profile support and got feedback that the new VAO support for functioning and enabling GL3 usage under OSX. I don't have a OSX system so can't personally test, the best I can do provide general directions for others who have OSX to do testing and roll in any fixes that are required. For yourself I would recommend having a look through the threads on VAO over the last two months looking for discussions on the OSX, this might help you on your way. You'll also need patience, Apple over the years have made various changes that break builds and runtimes, or limit functionality to a narrow set of usage cases. Over the years I have worked under OSX at different points, but these days I'm more than happy to stay away from OSX, Apple have moved the goal posts so many times that it's a painful platform to support. I say this prepare you for the effort required to port and then maintain your application on OSX, giving you the required time and resources for OSX support is something that your management will need to be aware of and supportive of. On the OSG side I can't wave a magic wand and fix all the problems, one of the main motivations for adding VAO support to the OSG was fixing things under OSX. I spent 6 weeks work unpaid on this to make it possible but as I don't have OSX I can't do the final testing. Others in the OSG that have OSX will need to help refine things if they need it and support each other.

I'm sorry but that did not work for me.

Thank you Robert for the extensive answer. I will test it today and provide feedback ASAP. Unfortunately OSX support is a requirement for my software. Thank you Tony for the link.

Re: [osg-users] glsl version 130 not supported (and related problems)
Hi Bruno, Apple have made life difficult for OpenGL developers in the way they have tackled modern OpenGL support so it tends to be awkward and behind the curve on latest features. It's the Apple way to mess developers around though, unfortunately you just have accept the rough with the smooth under OSX if you want to support it. Personally I wouldn't recommend OSX for OpenGL these days, so if you have choice then Windows or Linux will likely lead to an easier life. On the OSX front if you want to use the latest GL features you are forced to use OpenGL core profile and dump all the backwards compatibility support the other platforms provide. So have to build the OSG with the just the core profile enabled and fixed function disabled, you'll also need to use the latest OSG dev work (master is probably best) as it includes the VAO support you'll need. The OSG CMake system has an OPENGL_PROFILE var that you can set to GL3 or GLCORE via: cmake OPENGL_PROFILE=GLCORE If you are have already built the OSG then you'll want to remove the previous CMakeCache.txt to make sure the CMake runs all setup afresh. Once the OSG has been set up then you'll need to enable Vertex Array Object usage by setting the osg::DisplaySetting::setVertexBufferHint() with VERTEX_ARRAY_OBJECT prior to setting up the viewer i.e. osg::DisplaySettings::instance()->setVertexBufferHint(osg::DisplaySettings::VERTEX_ARRAY_OBJECT); osgViewer:Viewer viewer(..). ... Or set the default value via the OSG_VERTEX_BUFFER_HINT to VERTEX_ARRAY_OBJECT. Once the VAO work is more widely tested and debugged setting the VAO hint on by default should be possible, but for now it's still a manual step. I realise this is a bit of pain, but that's down to the games that Apple plays, provides sub par support and in a manner of it's choosing not the type of solution that best fits the needs of developers.

[osg-users] glsl version 130 not supported (and related problems)
Hello, I am using a fragment shader that requires #version 130 I use OSG 3.5.5 and Qt 5.7 on MacOS 10.12 This results in a shader compilation error, 'version 130 not supported' I tried compiling OSG with GL3 enabled, but the error persists. Then I tried to activate a Core Profile globally in Qt using QFurfaceFormat (just ensures that a 3.3. Core profile is set globally for all widgets): but after I do this and start using a Core profile, I get tons of errors from OSG pipeline and can't render anything at all. What should I do here?
