Addresses Courses, Seminars, Conferences, Workshops Collaboration with other groups. Visitors ... Information for our visitors General description The area of research. The Group. Research activities in Computational Geometry started at the UPC in the early nineties, with the work of Professors Hurtado, Noy, Serra and Trias. An official Line of Research (UPC code 12030905) was created in 1993, under the responsibility of Prof. F. Hurtado. Due to the background of many members of the Group, the interface with Combinatorics and Graph Theory is an specially active area of research. A research Subline on Computational Algebra has been recently created (1998), under the responsability of Prof. A. Montes, and another possible one on Geometric Software, which would be coordinated by Prof. J. Trias, is being considered. Ongoing research. The official projects currently alive are Combinatorial and algorithmic methods in discrete geometry (Research Project MCYT-MEC) and Algorithms and fundamental concepts for triangulations (Austria-Spain) this one jointly with the group at the Technical University of Graz. General research is also funded by the

It's free! Save it. Software for computer graphics represents three-dimensional space a little differently than one might expect. Euclidean geometry is not quite right. The usual approach uses what is called projective geometry, certainly one of the most beautiful systems in mathematics. Yet even with this approach, when the mathematics actually meets the computer code there are some awkward inconveniences. Perhaps the best solution may be what is called oriented projective geometry. This geometry was worked out in detail by Jorge Stolfi [10, 11] in 1987; it has also found more recent application in computer vision [6]. This paper is an elementary introduction to this still unfamiliar geometry from a coordinate-based point of view, restricted to three dimensions. It assumes only a background in linear algebra.

It allows complicated objects to be built as various ordered "union", "intersection" and "difference" of simpler objects, which may be bounded primitives or half-spaces. It is supported by the Boolean algebra and a set of well-understood regularized set operations. Constructive volume geometry (CVG) is a major generalization of CSG. Unlike CSG, CVG does not limit itself to geometrical operations only, and it can also be employed to manipulate physical properties that are associated with objects. Its combinational operations, mostly defined in the real domain, can be used to model complex interior structures of objects and amorphous phenomena in a constructive manner. In CVG, combinational operators are defined upon unbounded

135. Research Activity In recent years, there have been regular seminars in applied mathematics, analysis, computational geometry, computer science, magnetofluid dynamics, http://www.cims.nyu.edu/information/brochure/activity.html

Research Activity The Courant Institute's research activities are diverse, spanning the continuum from "pure" to "applied," both in mathematics and computer science. The Institute has long been a leader in the study of partial differential equations, with their many applications and ramifications. It is also strong in topics such as scientific computation and numerical analysis, which lie at the interface between mathematics and computer science. An unusual feature of the Institute is its breadth, which extends beyond the conventional boundaries of mathematics and computer science to include aspects of biology, engineering, linguistics, physics, and other areas of science. Central to the scientific life of the Institute is its lively program of research seminars . The purpose of these seminars is to stimulate education and research at the level where the two are synonymous. Seminars promote the formation of working groups by drawing students and visitors into contact with ongoing research activities. They also keep the Courant community abreast of new developments around the world. In recent years, there have been regular seminars in applied mathematics, analysis, computational geometry, computer science, magnetofluid dynamics, probability and statistical physics, numerical analysis, and programming languages. Additional seminars are organized each year depending on the interests of the faculty and postdoctoral visitors; recent examples include atmosphere/oceans, differential geometry, dynamical systems, mathematical finance, materials science, and neuroscience.

Next: Molecular surface and volume Up: Molecular Modeling Previous: Computer representation of chemical Computer representation of geometry Molecules are not static entities. Even at absolute zero temperature atoms in a molecule are actively vibrating. The molecular geometry represented by a static picture on the computer screen or a Dreiding model is therefore only an approximation. The term atom position The simplest way to specify molecular geometry to the computer is to list cartesian coordinates for each atom. In most cases the right-handed coordinate system is used, whose axes are perpendicular to each other (i.e., orthogonal), as represented in Fig. Figure 6.6: Cartesian system of coordinates with orthogonal axes. Cartesian coordinates are usually listed in 3-column format, X, Y, and Z coordinates for each atom. Sometime the coordinates are listed in natural crystal axes, called notional axes, which refer to the shape and dimensions of the unit cell. The notional axes are not generally perpendicular, and the coordinates are scaled by lengths of the unit cell edges. For the general case of a triclinic system, represented in Fig. , the edges of the unit cell along oblique axes, x y and z , are a b and c , respectively, and the interaxial angles: and , are denoted by

Computer Graphics/Geometric Design Group Overview Scientists and engineers often model and analyze the physical world. Computer graphics and geometric design are vital tools in this task. Consider the problem of designing mechanical parts for industrial applications such as automobile manufacturing. Computer models are replacing physical models. They are cheaper to construct, easier to change, and simpler to analyze. They enable a broad range of automated technologies including finite element analysis, process planning, robotics, and computer controlled manufacturing. Computer simulations save industry both time and money, and computer analyses of geometric models lead to better and cheaper products. Applications of these technologies include the design and manufacture of car bodies, ship hulls, airplane wings, and a large variety of mechanical components and assemblies. At the core computer graphics and geometric design is the fundamental problem of defining, representing and manipulating shape. As a result, the scope of computer graphics and geometric design is very broad. Related areas include automated design and manufacture, solid modeling, mesh generation, finite element analysis, computer animation, image and signal processing, computational geometry, computer vision, robotics, and scientific visualization.
