    glBlendEquationSeparateEXT on Radeons

    0r@ngE
      Hi!

      In my application I need for glBlendEquationSeparateEXT function

      glBlendFuncSeparateEXT( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_SRC_ALPHA, GL_DST_ALPHA );
      if ( glBlendEquationSeparateEXT )
      glBlendEquationSeparateEXT( GL_FUNC_ADD, GL_MAX );


      but on my HD3850 & HD4850 & HD2600
      wglGetProcAddress( "glBlendEquationSeparateEXT" ) returns NULL

      But if I write wglGetProcAddress( "glBlendEquationSeparate" ) (without EXT)
      it return correct address. But in extensions list (glGetString( GL_EXTENSIONS ))
      GL_EXT_blend_equation_separate is missing.

      Can you tell me what does it means and can I use that function, or it will be
      deprecated in future ?

      Thank you a lot for future answers
