   Finding SDK Extentions for OpenGL, to use latest version of OpenGL
  Someone gave me a link to this page saying that I needed the GLSDK at this page to have the extensions so that I could use the latest version, 1.5 of OpenGLhttp://oss.sgi.com/projects/ogl-sample/sdk.htmlIs this right???Cause since it''s not from the OpenGL page I got confused.All I want is to be able to use 1.5 of OpenGL.Thanks 
  I think all you need is the glext.h file.I also needed some extension (SEPARATE_SPECULAR_COLOR) which I could not access with my old glext.h, but now it works fine.You probably dont need the glsdk stuff to use version 1.5. It''s only a wrapper making the access to extensions a bit easier. I haven''t tried this one.
