	Computational geometry - Wikipedia, the free encyclopedia
		In computer science, computational geometry is the study of algorithms to solve problems stated in terms of geometry.
		Often, the latter kind of computational geometry is considered to be branch of computer graphics and/or CAD, and the former one is called simply computational geometry.
		The primary goal of research in combinatorial computational geometry is to develop efficient algorithms and data structures for solving problems stated in terms of basic geometrical objects: points, line segments, polygons, polyhedra, etc.

		As a consequence, the excitement of the computational geometry community at its theoretical accomplishments was mitigated by a sense of discomfort at the perceived loosening of ties with the very same applications that motivated the establishment of the discipline.
		Computational geometry is typically taught in specialized courses, or as a single short section in algorithms classes.
		Computational geometry is a lively discipline that is undergoing a crucial phase of its evolution.

		Computational geometry is the study of algorithms for solving geometric problems on a computer.
		The field of computational geometry is less than 20 years old and a thriving community of researchers has emerged working on fundamental problems relevant to several application domains including computer graphics, solid modeling, computer generated forces,virtual reality, simulated training, computer-aided ma nufacturing, robotics, computer vision, VLSI design, CAD/CAM, geographic information systems, and statistics.
		This all-new introduction to computational geometry is a textbook for high-level undergraduate and low-level graduate courses.

	Computational Geometry, Algorithms and Applications
		Computational geometry emerged from the field of algorithms design and analysis in the late 1970s.
		The choice of the applications was guided by the topics in computational geometry we wanted to cover; they are not meant to provide a good coverage of the application domains.
		Having said this, we believe that knowledge of computational geometry is important to solve geometric problems in application areas efficiently.

	Strategic Directions in Computational Geometry Working Group Report (Site not responding. Last check: 2007-10-07)
		As a testimony to the original success of this mission, the initial body of computational geometry literature had a prominent presence both in the field of theory of computing and in applied areas, such as graphics, robotics, mechanical engineering, and pattern matching (see, e.g., the 1984 survey of the area [LP84]).
		Researchers should be able to build and maintain a reputation within the computational geometry community, while at the same time making their applied results known to the community of the application area.
		The vision for many in the computational geometry community is that computational geometry emerge as the discipline where for geometry, theory meets practice, where problems of an applied nature inspire and inform research problems in computational geometry and mathematics, where theoretical results are implemented, made usable, and disseminated to application domains.

		FastGEO is a library that contains a wide range of highly optimized computational geometry algorithms and routines for many different types of geometrical operations such as geometrical primitives and predicates, hull construction, triangulation, clipping, rotations and projections.
		In the past it has been widely acknowledged by many computational geometers that vectorized primitives are in general the most efficient and highly optimized path for computational geometry solutions.
