best way to draw points in gl environment

    Hi all, I got this patch from forum cos I was looking for a way to make points style picture in GL, this guy use a gen converter to make it, but when i change the mesh draw_mode to lines, I found there's lots lines (height?) anyone knows what is that? since he coordinates grey scale to x y, hence are those lines z axis? it causes so much trouble when I try to transpos my mesh, anyone knows a good way just to draw point image in gl or how to remove those lines please? I hope I describe my question okay...
    ps. eventually my goal is to make points image transform into particles
