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.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
