[osg-users] OSG using OpenGL 3.2 in Mac OS X 10.7 (Lion)
Hi David -- I posted your change #1 to osg-submissions. (To refresh your memory, this is the fix for how OpenGL.h is included by the include/osg/GL header.) With this change, we (at least) have OSG trunk building for GL3 on OSX 10.7. To actually get it running (i.e., support for forward compatible / core profile, vertex array objects, etc), that can be a follow-on submission. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG using OpenGL 3.2 in Mac OS X 10.7 (Lion)
HI David,
The OSG is designed to check for extensions at runtime, so even if you
compile the OSG against OpenGL 1.1 it will still be able to load up
OpenGL 3.2 features at runtime and use them.
The CMake option to compile specifically against OpenGL 3 is for when
you want to compile against OpenGL 3 without the backwards
compatibility to OpenGL 2.x, this disables all the fixed function
pipeline. This is something you might want, but it's mostly not
necessary.
Robert.

The question is now, can OpenGL 3.2 be use in Mac OS X? I'm doing something
wrong?

Re: [osg-users] OSG using OpenGL 3.2 in Mac OS X 10.7 (Lion)
Since release 3.0.0, OSG has supported OpenGL versions 3.0 on Windows. On svn
trunk, see the example 'osgsimplegl3', especially the comment block at the end
of the file that discusses building OSG for GL3 use.
But to my knowledge no one has contributed code to make it work on OS X or
Linux. Please do so, if you need that functionality.

Besides the specific CMAKE_VARIABLES to get Open GL 3 support on OS X
GraphicsWindowCocoa needs some love when creating a graphics context.
Just setting the NSPixelFormat to
NSOpenGLPixelFormatAttribute pixelFormatAttributes[] =
{
NSOpenGLPFAOpenGLProfile, NSOpenGLProfileVersion3_2Core,
0
};
when compiling for Open GL 3 should help.

Hi,I have been able to compile it for GL3 (both in 3.0 and 3.1 branches).I did the following modifications:1) In GL I add two includes, three defines for missing symbols and an ifdef __APPLE__ #if defined(OSG_GL3_AVAILABLE) #ifdef __APPLE__ #include OpenGL/OpenGL.h #include OpenGL/gl3.h #define GLint64EXT GLint64 #define GLuint64EXT GLuint64 #define GL_BGRA_EXT GL_BGRA #else #include GL3/gl3.h #define GL3_PROTOTYPES 1 #endif2) When compiling my original cmake line lacks extra defines (as seem inosgsimplegl3.cpp).
