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 & softpipe) Map buffer subranges (GL_ARB_map_buffer_range) DONE Float textures, renderbuffers some infrastructure done (incl. GL_EXT_packed_float, GL_EXT_shared_exponent) Framebuffer objects (GL_EXT_framebuffer_object) DONE Half-float some infrastructure done Multisample blit DONE Non-normalized Integer texture/framebuffer formats ~50% done 1D/2D Texture arrays core Mesa, swrast 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 DONE (swrast, i965, gallium) Transform feedback (GL_EXT_transform_feedback) ~50% done glBindFragDataLocation, glGetFragDataLocation, glBindBufferRange, glBindBufferBase commands Vertex array objects (GL_APPLE_vertex_array_object) DONE sRGB framebuffer format (GL_EXT_framebuffer_sRGB) not started glClearBuffer commands DONE glGetStringi command DONE glTexParameterI, glGetTexParameterI commands DONE glVertexAttribI commands DONE (but converts int values to floats) GL 3.1: GLSL 1.30 and 1.40 not started Instanced drawing (GL_ARB_draw_instanced) DONE (gallium, swrast) Buffer copying (GL_ARB_copy_buffer) DONE Primitive restart (GL_NV_primitive_restart) DONE (gallium) 16 vertex texture image units not started Texture buffer objs (GL_ARB_texture_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 ~50% done 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) DONE (swrast, gallium) Provoking vertex (GL_ARB_provoking_vertex) DONE Seamless cubemaps (GL_ARB_seamless_cube_map) DONE, mostly?
