Description

Interface Summary

BoxInformation	An Oriented Box is a rectangle that is rotated about its bottom right corner.
HasCentroid	Interface for all geometric objects that have some concept of a 'centroid'.
Moveable	Instances of this interface allow movement along the 8 cardinal directions.

Class Summary

AbstractMoveable	Implements the 'move' method using the 'shift' method.
BoundingBox	This class reprsents a rectangle aligned with the coordinate axes or a set of such rectangles.
Circle	A circle, specified by the center point and the radius in integer format, supporting functions necessary for simple comparison.
Component	Represents a homogonous vector.
ConvexPolygon	A class representing a Convex Polygon.
Ellipse	An ellipse.
GeometryTest	Testsuite for the geometry package.
OrientedBox	An Oriented Box is a rectangle that is rotated about its bottom right corner.
Pnt	Represents a 2d point in Rational format.
Polygon	This class represents a series of line segments.
PolyLine	This class represents a series of line segments.
PolyList	This class represents the intersection / union of several Convex Polygons.
Rational	Represents numbers as a fraction with two BigIntegers.
Squiggle	Represents a squiggly line as a list of connected line segments.
Util	A set of utility static methods for dealing with the viper geometry package.

Package edu.umd.cfar.lamp.viper.geometry Description

A set of classes for manipulating geometric data, usually used for ViPER attribute data.

Included are classes for dealing with polygonal data, which inherit from viper.geometry.PolyList. There are also some classes for dealing with , but that proved too slow and most of it has been deactivated. There is also a class for dealing with rational numbers, necessary for certain operations on polygons (notably, intersection of lines).
