99cb8ebacf Added more flexibility into the State::checkGLErrors() method, allowing calling code to pass in two strings.
Improved the StateSet::compileGLObjects() usage of checkGLErrors() to make the warning reports more meaningful.

94891778c4 Restructred the enabling of vertex array object support to allow one to set enable the default via osg::State.

Restructred BufferObject assigned in osg::Geometry

4b2912e096 From John Farrier, "Best I can tell, there is an enumeration for NEVER_CHECK_GL_ERRORS in CheckForGLErrors, defined in State. State.cpp does check to see if you want MORE error checking, but there is no way to turn OFF error checking. This change allows disabling of OpenGL error checking." 2016-01-25 10:45:07 +00:00
Robert Osfield
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.

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.

bead0740f2 From Aurelien Albert, "This submission allow the user to specify how to setup VertexAttributeAliasing.
I think this is necessary on OpenGL 3.2+ since this is no more "default" locations in the OpenGL specs.

The default behaviour stay the same.

There is a few new methods on osg::State :

- resetVertexAttributeAlias : reset all vertex alias to osg's default ones
- set**Alias : set a vertex attribute alias configuration
- setAttributeBindingList : set the attribute binding list (allow to specify an empty list if you're using "layout" qualifier in glsl code to specify the bindings. This save some CPU operations)"

4b223c770b From Michael Bach Jensen and Robert Osfield, "As discussed (http://forum.openscenegraph.org/viewtopic.php?t=12027) here is my submission :-)
The following change to State.cpp fixes the case where textures in a stateset along with a compute shader program did not make those textures available to the shader, since it got evaluated before the texture bind(s)."

Note from Robert, Michael only change State::apply(StateSet*) so I also applied the same reversal in apply of texutre modes/state into the State::apply() method for consistency.

382c3322c9 From Farshid Lashkari, "I just started looking into the shader composition feature. I enabled shader composition on the osg::State object and noticed a 6x increase in draw time. I figured that the default composer might have performance issues, so I created a custom ShaderComposer that overrides "getOrCreateProgram" and does nothing. This still resulted in a performance drop.
I looked into the "State::applyShaderComposition" method and noticed that it will print debug information to the osg::INFO stream. I commented that line out and the performance drop was gone.

I'm not sure if the printing was accidentally left in or is meant to be enabled. I've modified the function to only call the print function if INFO logging is enabled. I've attached the change."
