   Latest OpenGL Header Files/Libraries
  Ok, I''m working with some textures and I''m trying to do the following (I''m tileing textures as a background and I''m trying to get rid of those nasty lines that are appearing between them):glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);pretty simple... I found a few examples of this in the red book... my problem is that when I compile using VC++6.0, I get that GL_CLAMP_TO_EDGE is undefined.  Now I realize that GL_CLAMP_TO_EDGE is OpenGL 1.2 and later, which makes me think that my gl.h and libraries are 1.1   Where/How do I get the latest librarys and header files.  I have looked on google and all I can get is that www.opengl.org says they come with the Windows 2000.  I downloaded ATI''s OpenGL SDK to see if it is something that will come from the graphics card vendor but it didn''t appear to have an updated gl.h...  Am I just not looking in the right places????Any help would be appreciated.ThanksChris 
  You have to include glext.h in your project.  It contains all the variables and functions you need. ;  Where do I find that???  Is it the same as glut.h? ;  no it''s not the same. you can find it here. ;  Thanks for your help... I will try it. ;  FYI, this is covered in detail in the Forum FAQ
