Lines are widely use in three-dimensional graphics. Most graphics systems render lines with a color independent of the lighting conditions in the scene. Correct lighting of lines can improve the visual appearance of scenes with many lines or long lines significantly. This paper will explain the lighting calculations used in MathGL3d and show some applications for visualization of dynamical systems and field lines. MathGL3d uses free programmable 3d graphics hardware to modify the lightning calculation for lines and can display scenes with 3∑a vertices in the lines in real-time.
