This question should probably be posted in the OpenGL forum of this site. Not sure what you mean by lines with 'round edges'. I've attached a figure that shows how to round off the corners and end points of a series of line segments. It's done by simply drawing anti-aliased points of the same width of the lines at the end of each line segment. So you are drawing the line segments twice: 1) once as anti-aliased lines, and 2) as anti-aliased points. Does this answer your question?
