\section P2T2_Performance Performance
The performance of the 2D periodic Delaunay triangulation is compared
to the Euclidean 2D Delaunay triangulation. The plot shows the running
time in seconds for different numbers of batch inserted points. The
points are uniformly randomly distributed in the unit rectangle. The
tests were done on an Intel i7 @ 2.67GHz.
to the Euclidean 2D Delaunay triangulation. The points are inserted in
the Euclidean 2D Delaunay triangulation using spatial sorting. In the
Periodic triangulation the points are first inserted in random order
until the triangulation is valid in the 1 sheeted covering space. The
remaining points are then inserted using spatial sorting. For the
large point set, first dummy points are inserted to create a valid
triangulation in the 1 sheeted covering space. Then all points are
inserted using spatial sorting. As a final step, the dummy points are
removed again.
