(LaTeX) Abstract:
We describe the following data structures. For halfspace range reporting,
in 3-space using expected preprocessing time $O(n\log n)$, worst case storage
$O(n\log\log n)$ and worst case reporting time $O(\log n+k)$ where $n$ is
the number of data points and $k$ the number of points reported; in $d$-space,
with $d$ even, using worst case preprocessing time $O(n\log n)$ and storage
$O(n)$ and reporting time $O(n^{1-1/\lfloor d/2\rfloor}\log^c n+k)$. For ray
shooting in a convex polytope determined by $n$ facets using deterministic
preprocessing time $O((n/\log n)^{\floor{d/2}}\log^c n)$ and storage $O((n/
\log n)^{\lfloor d/2 \rfloor}2^{\log^* n})$ and with query time $O(\log n)$.
For ray shooting in arbitrary direction among $n$ hyperplanes using preprocessing
$O(n^d/ \log^{\floor{d/2}} n)$ and query time $O(\log n)$. We also
describe algorithms to construct the $k$-level of $n$ planes in 3-space dual
to points in convex position: the first one is randomized and uses nearly optimal
expected time $O(n\log n + nk2^{c\log^* k})$ and the second one is deterministic
and uses time $O(nk\log^c n)$. By a standard geometric transformation the same
time bound applies for the construction of the $k$-order Voronoi diagram of $n$
sites in the plane.
