Status of OpenGL 3.x features in Mesa Note: when an item is marked as "DONE" it means all the core Mesa infrastructure is complete but it may be the case that few (if any) drivers implement the features. Feature Status ----------------------------------------------------- ------------------------ GL 3.0: GLSL changes (GL_EXT_gpu_shader4, etc) not started Conditional rendering (GL_NV_conditional_render) DONE (swrast only) Map buffer subranges (GL_APPLE_flush_buffer_range) not started Float textures, renderbuffers some infrastructure done Framebuffer objects (GL_EXT_framebuffer_object) DONE Half-float some infrastructure done Multisample blit DONE Non-normalized Integer texture/framebuffer formats not started 1D/2D Texture arrays mostly done Packed depth/stencil formats DONE Per-buffer blend and masks (GL_EXT_draw_buffers2) DONE GL_EXT_texture_compression_rgtc not started Red and red/green texture formats Ian? Transform feedback (GL_EXT_transform_feedback) not started Vertex array objects (GL_APPLE_vertex_array_object) DONE sRGB framebuffer format (GL_EXT_framebuffer_sRGB) not started glClearBuffer commands DONE, except for dispatch glGetStringi command DONE, except for dispatch GL 3.1: GLSL 1.30 and 1.40 not started Instanced drawing (GL_ARB_draw_instanced) not started Buffer copying (GL_ARB_copy_buffer) DONE Primitive restart (GL_NV_primitive_restart) not started 16 vertex texture image units not started Texture buffer objs (GL_ARB_textur_buffer_object) not started Rectangular textures (GL_ARB_texture_rectangle) DONE Uniform buffer objs (GL_ARB_uniform_buffer_object) not started Signed normalized texture formats not started GL 3.2: Core/compatibility profiles not started GLSL 1.50 not started Geometry shaders (GL_ARB_geometry_shader4) partially done (Zack) BGRA vertex order (GL_ARB_vertex_array_bgra) DONE Base vertex offset(GL_ARB_draw_elements_base_vertex) DONE Frag shader coord (GL_ARB_fragment_coord_conventions) not started Provoking vertex (GL_ARB_provoking_vertex) DONE Seamless cubemaps (GL_ARB_seamless_cube_map) DONE, mostly? Multisample textures (GL_ARB_texture_multisample) not started Frag depth clamp (GL_ARB_depth_clamp) DONE Fence objects (GL_ARB_sync) DONE More info about these features and the work involved can be found at http://dri.freedesktop.org/wiki/MissingFunctionality
