for cubic curves has developed into a paper (Eigenwillig, Kettner,
Wolpert, Schömer: "Complete, exact, and efficient computations with
cubic curves") which was accepted to SoCG 2004.
Within the AG1 noon seminar, I would like to do a practice run of my
conference talk (length: 20 minutes, including questions).
I'd specifically like to invite the _non-experts_ on exact geometry
for curved objects to get a realistic simulation of SoCG.
