To select standard OpenGL 1/2 build with full backwards and forwards comtability use:
./configure
make
OR
./configure -DOPENGL_PROFILE=GL2
To select OpenGL 3 core profile build using GL3/gl3.h header:
./configure -DOPENGL_PROFILE=GL3
To select OpenGL Arb core profile build using GL/glcorearb.h header:
./configure -DOPENGL_PROFILE=GLCORE
To select OpenGL ES 1.1 profile use:
./configure -DOPENGL_PROFILE=GLES1
To select OpenGL ES 2 profile use:
./configure -DOPENGL_PROFILE=GLES2
Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.
From Robert Osfield, changed Roni's code to use a #define GETDEVICEPIXELRATIO to access the versioned Qt devicePixelRatio() method to avoid duplication of the Qt version checking.
- renamed osgQt::GraphWidget to osgQt::GLWidget
as it better fits to Qt naming (osgQt::GLWidget is derived from QGLWidget
while recent GraphWidget... it is unclear, maybe QGraphicsView,
QGraphicsScene,....)
- added the code to properly manage ON_DEMAND rendering scheme
(involves osgQt::setViewer() and internal HeartBeat class)
- added forward key events functionality. It allows to not eat the key events
by GLWidget, but it forwards them to Qt processing as well.
- destroying GLWidget before GraphicsWindowQt and vice versa does not crash
the application
- it is possible to request particular QGLFormat in GLWidget constructor
- added QtWindowingSystem class
- multithread OSG rendering improvements/fixes

From Robert Osfield, added back in getGraphWidget() method for backwards compatibility.
