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