Hello,
i have created a new class LineRenderer3D, which combines LineAndShapeRenderer with an Effect3D. If someone needs this, or you want to implement this class in the next Release of JFreeChart, ask me for code.
Greetings,
Tobi

I would be interested to incorporate this into JFreeChart.

here is the code of my class, maybe some changes hav to be done, to make it suitable for the library. This code works fine for my application.
