The Eucart Geometry Package is a library of subroutines providing efficient
solutions for a comprehensive set of common geometry problems arising in 2
dimensions.  The package eliminates the time consuming and error-prone
process of implementing solutions to problems that are conceptually simple
but difficult in practice.

Special attention has been paid to the numerical accuracy and stability of
the solutions.

The Geometry Package will be of special interest to software developers
working in the areas of computer graphics, CAD/CAM, cartography, and GIS.

Product Features

Supports points, segments, rays, lines, triangles, rectangles, bounding
boxes, and simple and self-intersecting polygons.  This provides a
sufficient set of object primitives required for most applications.

Operations include angular orientation, length, perimeter, area, closest
points, intersection query, intersection result, planar subdivision, and
polygon reduction.  These are the common geometric operations required for
most applications.

Arbitrarily complex, self-intersecting polygons can be reduced to a set of
simple, distinct polygons.  Applications no longer need be restricted to
special case simple polygons.

New algorithms, invented by Eucart Consulting using state-of-the-art data
structures and methodologies, are employed throughout the package.  This
results in faster, more accurate, and more robust applications.

A variety of error handling techniques are provided including return codes,
message strings, and callbacks.  Applications have the option of choosing
the most appropriate means of error notification.
