Link to the new ARB extensions

Along with the OpenGL 3 and GLSL 1.3 specifications, the OpenGL Working Group has also released a number of ARB extensions which bring any OpenGL 3 core functionality to OpenGL 2.1 if possible. Although the OpenGL 3 specification’s ARB extension annex doesn’t list them, they are available on the OpenGL Extension Registry. Below are direct links to the extension specifications. Most of them are the ARB form of NVIDIA’s Shader Model 4 EXT extensions.

• GL_ARB_depth_buffer_float
• GL_ARB_draw_instanced
• GL_ARB_framebuffer_sRGB
• GL_ARB_geometry_shader4
• GL_ARB_half_float_vertex
• GL_ARB_instanced_arrays
• GL_ARB_map_buffer_range
• GL_ARB_texture_buffer_object
• GL_ARB_texture_compression_rgtc
• GL_ARB_texture_rg
• GL_ARB_vertex_array_object
