   How to connect GL_TRIANGLE_STRIP?
  The default triangle strip has some limitations when it comes to edges. I drew a line with GL_TRIANGLE_STRIP and if there are angles > 90° and the line width increases, the lines become not really a strip but a set of single lines. Line seen here: http://img14.imageshack.us/img14/7662/linejpe.jpg (why the hack isn't that clickable?)Is it possible, without the overhead of transforming them to polygons to connect the corners?Thanks   
  I assume you mean GL_LINE_STRIP. Aside from that, AFAIK there's no way to make smooth lines with GL_LINE_STRIP.Oh, and btw: to make your link clickable, add <a href="http://img14.imageshack.us/img14/7662/linejpe.jpg">your text</a> (with the url in double quotes).Like so: your text;  Yes sorry, its the GL_LINE_STRIP of course :) and too bad, got to triangulate it ...Btw, thanks for the link info, didnt know it is possible to use html tags here
