Thin and long objects

Hi,

scene rendered by my application contains some thin and long cylinders (radius=3 units, length=3000 units). When I try to render this scene in a 300x300 window these cylinders not always rendered by OpenGL and sometimes they are rendered only partially. I understand that being scaled into 300x300 window these cylinders have diameter only about 0.5 pixel but I’d like to see them rendered always at least as 1 pixel line. Is it possible with OpenGL?

Thanks

perhaps with each cylinder also draw a line ( GL_LINE ) inside from the top to bottom, the lines will retain the same screen width no matter how far from the camera they are

Multisample might help (Don’t know for sure though).
