1. 376+xiii pages, 270 exercises, 210 figures, 259 references.
2. Although I've retained the title "...in C," all code
has been translated to Java, and both C and Java code is available
via links from http://cs.smith.edu/~orourke.
3. A Java Applet permits interactive use of the code. See previous URL.
4. First Edition code improved: Postscript output, more efficient,
5. New code (see below).
6. Expanded coverage of randomized algorithms, ray-triangle intersection,
and other topics (see below).
1. approx. 50 pages longer
2. 31 new figures.
3. 49 new exercises.
4. 74 new references
5. 4 new programs.
1. To compute the Delaunay triangulation from the 3D hull in O(n^2).
2. To intersect a ray with a triangle.
3. To decide if a point is inside a polyhedron.
4. To compute the convolution (Minkowski sum) of a convex polygon with
a general polygon.
5. To generate regularly distributed points on the surface of a
Significant code improvements:
1. Triangulation code now O(n^2) rather than n^3.
Uses lists rather than arrays.
2. Graham scan handles collinear points more cleanly.
3. Convex hull in 3D starts with double-covered triangle.
Volume determinant computations much faster. Overflow handled better.
4. Segment-segment intersection code handles special cases cleanly.
5. Point-in-polygon code classifies all boundary points correctly.
6. Intersection of convex polygons handles special cases more uniformly.
7. Robot arm configuration more robust.
New coverage of these topics:
1. Partition into monotone mountains (for triangulation).
2. Randomized trapezoid decomoposition.
3. Randomized triangulation.
4. The ultimate convex hull algorithm.
5. Randomized 3D hull construction.
6. Twin edge data structure.
7. Furthest-point Voronoi diagram figure.
8. Red-blue matching.
9. Intersection of segment and triangle.
11. The Bentley-Ottmann algorithm for intersecting segments.
12. Boolean operations between two polygons.
13. Segment search tree.
14. Sources and further reading: annotated bibliography.
