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."

478e0f3ebf From Jorge Ciges, "1rst - Changes in Cmake: They make possible "make install" with the android building.
2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.

3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.

4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8

5th - OpenGL and GLSL version identification changed to recognize GLES  versions properly

1d55efb721 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. 2011-02-14 12:54:21 +00:00

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."

b199a334d9 Introduced OSG_GL*_FEATURES macros defined in include/GL that are set to 0 or 1 according to what the assocoated version of GL is compiled against.
Removed EXT postfix of FrameBufferObject functions, and added support for checking non EXT versions frame buffer object GL functions.

Introduced usage of OSG_GL*_FEATURES to avoid some #if #else #endif code blocks.

Using a submissions from Paul Martz as a guide added perliminary GL3 support to a range of OSG classes
