d49f0d67af change the design of BufferIndexBinding to work with BufferData instead of BufferObject
allow convenient BufferData abstraction +  serialization of BufferIndexBinding

949aca196d Refactored handling of StateAttiribute's that override the StateAttiribute::getMember() so that when they change their Member value they update the StateSet parents that own them to keep the StateSet's maps coherent. 2016-06-25 12:24:19 +01:00

78b99c7143 Refactored osg::TextureBuffer to support assigning any type of osg::BufferData rather than just osg::Image as was previously required.
Refactored osgforest and osggpucull examples to take account of changes to TextureBuffer.

Added osg::DrawIndirectBufferBinding.

1b6e50a2dd From Marcus Hein, Added support for OpenGL SSBO and SSBB via osg::ShaderStorageBufferObject and osg::ShaderStorageBufferBinding to core OSG library, and added new osgSSBO example

aab27e106c From David Callu, "Here an update of osg::Uniform :
- add non square matrix
- add double
- add all uniform type available in OpenGL 4.2
- backward compatibility for Matrixd to set/get an float uniform matrix
- update of IVE / Wrapper ReadWriter

implementation of AtomicCounterBuffer based on BufferIndexBinding

add example that use AtomicCounterBuffer and show rendering order of fragments,
original idea from geeks3d.com."

e5a9eaa711 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."
