8fc287c1b7 Added asUpdate/Cull/EventVisitor and asCamera/asDrawable to osg::Object and usage of these within the code base to avoid dynamic_cast<> usage. 2016-01-20 17:49:10 +00:00

161246d864 Refactored the GL object deletion management to use new osg::GraphicsObjectManager/GLObjectManager base classes, and osg::ContextData container. 
This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

b90503fdf5 Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based 
on defines passed in from osg::StateSet::setDefine(..).

f8c4ad4b90 From Pjotr Svetachov, "I was experimenting with VBO's to try to get them on par with display 
lists when drawing lots of batches and noticed that my program
generated a lot of unneeded glClientActiveTexture calls. Digging
deeper I found out it came from State::disableTexCoordPointer where
the function would call glClientActiveTexture but not
glDisableClientState because the geometry didn't have texture
coordinates for that channel. This is because in our scene there are
some geometries that have move than one uv channels making
State::_texCoordArrayList grow. Then the method
State::applyDisablingOfVertexAttributes() will call
disableTexCoordPointer multiple times.

I rearrange the method a little to combat this. Now the logic has the
same ordering as disableTexCoordPointersAboveAndIncluding which
already combats this."

7dc3b34bfd Removed State::AppliedProgramObjectSet container and Obsever usage from osg::State to address threading bug crash. 
The State::AppliedProgramObjectSet wasn't ever being used actively in the current rev of the OSG so populating and clearing was no longer neccessary, allowing the code to be removed completely.

5597248895 Introduced new scheme for setting up which version of OpenGL/OpenGL ES the OSG is compiled for. 
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.
