    Okay I found the answer in a book for perl. Obviously packing the arrays or giving reference isnt good enough
    glMaterialfv_p(GL_FRONT, GL_SPECULAR, 1, 1, 1, 1); glMaterialfv_p(GL_FRONT, GL_SHININESS, 50); glLightfv_p (GL_LIGHT0, GL_POSITION, 1, 1, 1, 0);
    did the trick
      Hi, I'm using the latest SVN rev from New Perl OpenGL Release. I found that I also had to remove the line glEnable(GL_LIGHTING); from init, or the screen was black. By the way, if you havn't seen it, there is a very nice example in the SVN rev called isosurf.pl, that is where I found those function's need for arrays. Isosurf.pl looks like it displays DNA type shapes, maybe you will find it contains some useful ideas.

      P.S. I'm running the NVidia driver on linux.
