Ray shooting, implicit point location, and related problems form the core of this research. The author presents efficient techniques for answering various queries on planar arrangements of segments and certain related structures. These techniques extend and modify recent efficient techniques for half-plane range searching to obtain algorithms for answering efficiently several types of queries on arrangements of segments and certain related structures. A typical example is the implicit point location problem â" given such an arrangement A, preprocess it so that, given any query point x, we can calculate quickly certain properties of the face of A containing x. The results of this book have been conceived and developed in the summer of 1987, but for various reasons were left unpublished for almost two years. Meanwhile, there has been significant progress on the problems studied here. In particular, a recent work by Agarwal presents techniques that achieve query time roughly O(sqrt(n)) and involve deterministic, rather than randomized, preprocessing. Agarwal's results are based on a decomposition technique that is different from the one used in this book. Still, many of Agarwal's arguments are taken from this book. As a public service, to make our results somewhat more accessible, the author has decided to elevate this book from the status of unpublished manuscript to that of a technical report. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
