1 2Status of OpenGL 3.x features in Mesa 3 4 5Note: when an item is marked as "DONE" it means all the core Mesa 6infrastructure is complete but it may be the case that few (if any) drivers 7implement the features. 8 9 10Feature Status 11----------------------------------------------------- ------------------------ 12 13GL 3.0: 14 15GLSL changes (GL_EXT_gpu_shader4, etc) not started 16Conditional rendering (GL_NV_conditional_render) DONE (swrast & softpipe) 17Map buffer subranges (GL_ARB_map_buffer_range) DONE 18Float textures, renderbuffers some infrastructure done 19 (incl.
