From Art Tevs, "A new texture class Texture2DArray derived from Texture extends the osg to support the new EXT_texture_array extensions. Texture arrays provides a feature for people interesting in GPGPU programming. Faetures and changes: - Full support for layered 2D textures. - New uniform types were added (sampler2DArray) - FrameBufferObject implementation were changed to support attaching of 2D array textures to the framebuffer - StateSet was slightly changed to support texture arrays. NOTE: array textures can not be used in fixed function pipeline. Thus using the layered texture as a statemode for a Drawable produce invalid enumerant OpenGL errors. - Image class was extended to support handling of array textures Tests: I have used this class as a new feature of my application. It works for me without problems (Note: Texture arrays were introduced only for shading languages and not for fixed function pipelines!!!). RTT with Texture2DArray works, as I have tested them as texture targets for a camera with 6 layers/faces (i.e. replacement for cube maps). I am using the array textures in shader programming. Array textures can be attached to the FBO and used as input and as output."

From Tim Moore, "Here is initial support for uniform buffer objects. The binding between a buffer object and an indexed target is implemented as a new StateAttribute, UniformBufferBinding. I've included an example program based on the code in the ARB_uniform_buffer_object specification. A few things remain to do: * The binding between a uniform block in a shader program and a buffer indexed target number is fixed, like a vertex attribute binding. This is too restrictive because that binding can be changed without relinking the program. This mapping should be done by name in the same way that uniform values are handled i.e., like a pseudo state attribute; * There's no direct way yet to query for the offset of uniforms in uniform block, so only the std140 layout is really usable. A helper class that implemented the std140 rules would be quite helpful for setting up uniform blocks without having to link a program first; * There's no direct support for querying parameters such as the maximum block length, minimum offset alignment, etc. Having that information available outside of the draw thread would make certain instancing techniques easier to implement."

// ARB_get_program_binary
#ifndef GL_ARB_get_program_binary
From Michael Platings, I've added initial support to osg for glGetProgramBinary and glProgramBinary. This means that shader programs can now be cached to disk and later reloaded, which is much faster than linking shaders from source code. This should mean significantly shorter load times for people who use lots of combinations of shaders.

From Tim Moore, "Here is initial support for uniform buffer objects. The binding between a buffer object and an indexed target is implemented as a new StateAttribute, UniformBufferBinding. I've included an example program based on the code in the ARB_uniform_buffer_object specification. A few things remain to do: * The binding between a uniform block in a shader program and a buffer indexed target number is fixed, like a vertex attribute binding. This is too restrictive because that binding can be changed without relinking the program. This mapping should be done by name in the same way that uniform values are handled i.e., like a pseudo state attribute; * There's no direct way yet to query for the offset of uniforms in uniform block, so only the std140 layout is really usable. A helper class that implemented the std140 rules would be quite helpful for setting up uniform blocks without having to link a program first; * There's no direct support for querying parameters such as the maximum block length, minimum offset alignment, etc. Having that information available outside of the draw thread would make certain instancing techniques easier to implement."

From Tim Moore, "Here is initial support for uniform buffer objects. The binding between a buffer object and an indexed target is implemented as a new StateAttribute, UniformBufferBinding. I've included an example program based on the code in the ARB_uniform_buffer_object specification. A few things remain to do: * The binding between a uniform block in a shader program and a buffer indexed target number is fixed, like a vertex attribute binding. This is too restrictive because that binding can be changed without relinking the program. This mapping should be done by name in the same way that uniform values are handled i.e., like a pseudo state attribute; * There's no direct way yet to query for the offset of uniforms in uniform block, so only the std140 layout is really usable. A helper class that implemented the std140 rules would be quite helpful for setting up uniform blocks without having to link a program first; * There's no direct support for querying parameters such as the maximum block length, minimum offset alignment, etc. Having that information available outside of the draw thread would make certain instancing techniques easier to implement."

From Michael Platings, I've added initial support to osg for glGetProgramBinary and glProgramBinary. This means that shader programs can now be cached to disk and later reloaded, which is much faster than linking shaders from source code.

From Tim Moore, "Here is initial support for uniform buffer objects. The binding between a buffer object and an indexed target is implemented as a new StateAttribute, UniformBufferBinding. I've included an example program based on the code in the ARB_uniform_buffer_object specification. A few things remain to do: * The binding between a uniform block in a shader program and a buffer indexed target number is fixed, like a vertex attribute binding. This is too restrictive because that binding can be changed without relinking the program. This mapping should be done by name in the same way that uniform values are handled i.e., like a pseudo state attribute; * There's no direct way yet to query for the offset of uniforms in uniform block, so only the std140 layout is really usable. A helper class that implemented the std140 rules would be quite helpful for setting up uniform blocks without having to link a program first; * There's no direct support for querying parameters such as the maximum block length, minimum offset alignment, etc. Having that information available outside of the draw thread would make certain instancing techniques easier to implement."

From Michael Platings, I've added initial support to osg for glGetProgramBinary and glProgramBinary. This means that shader programs can now be cached to disk and later reloaded, which is much faster than linking shaders from source code. This should mean significantly shorter load times for people who use lots of combinations of shaders.
