Introduction
At present there is really nothing here regarding computer graphics per se; this is primarily focused on computational geometry. In keeping with the general pattern of use of the Mathematics Subject Classifications, computational topics primarily focused on geometry are classified in sections 51: Geometry and 52: Convex Geometry and their subareas such as 52B: Polygons and polyhedra . This classification is intended for topics whose geometric aspects are fairly straightforward, but for which the main questions involve efficient, accurate computation. Many geometric questions arise involving large sets of points (e.g. which of these points are closest together?) which are arguably combinatorics or statistics , but we have included them here.
Applications and related fields
Some problems (e.g. finding the best circle passing through some points) are considered Statistics.

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

• The Graphics Gems Repository is the on-line repository for the code and errata for the Graphics Gems series of books (from Academic Press ). This series focusses on short to medium length pieces of code which perform a wide variety of tasks. There are many great documents and code bits at David Eberly's site , including a quaternion tutorial and code, animation information, image analysis, etc. The journal of graphics tools has source available on-line for some of the articles it publishes. The book Numerical Recipes is now online in Postscript and PDF forms. Some figures are missing from the PDF files, but you can't beat the price. The text is free for viewing but the electronic version of the source code must be purchased. WUArchive has a lot of (older) graphics software and other resources available. I know you get dumped into a directory listing using this link, but many of the subdirectories each have an HTML guide.

Temporarily unavailable - no date available A basic problem in computer vision is to understand the structure of a real world scene given several images of it. Techniques used in the book for solving this are taken from projective geometry and photogrammetry. The authors cover the geometric principles and their algebraic representation in terms of camera projection matrices, the fundamental matrix and the trifocal tensor. The theory and methods of computation of these entities are discussed with real examples, as is their use in the reconstruction of scenes from multiple images. Recent major developments in the theory and practice of scene reconstruction are described in detail in a unified framework. The authors provide comprehensive background material, so a reader familiar with linear algebra and basic numerical methods will be able to understand the projective geometry and estimation algorithms presented, and implement the algorithms directly from the book.

It gives a thorough overview of current linear and nonlinear scale-space theory, presenting many viewpoints such as the variational approach, curve evolution and nonlinear diffusion equations. The book is meant for computer vision scientists and students, with a computer science, mathematics or physics background. Appendices explain the terminology. Many illustrated applications are given, e.g. in medical imaging, vector valued (or coupled) diffusion, general image enhancement (e.g. edge preserving noise suppression) and modeling of the human front-end visual system. Some examples are given to implement the methods in modern computer-algebra systems. From the Preface by Jan J. Koenderink:

Organized by R. Cipolla, J. Lasenby, H.C. Longuet-Higgins and A. Zisserman Computer vision is the automatic analysis and interpretation of images of real scenes. To date, geometric methods constitute the most useful tools for this analysis. The adoption of projective geometry in the mid-1980's, as a supplement to Euclidean geometry, provided a new approach to many computer vision problems and has led to improved recognition methods and a better understanding of the geometry of multiple views, particularly in the case of uncalibrated cameras. A combination of differential geometry and motion analysis has produced new algorithms for determining surface shape from the temporal evolution of image curves, and a fusion of geometry and statistics has resulted in powerful methods of tracking image features. The meeting will describe recent developments in such techniques, including their implementation in working systems.

Computer Experience:
For more than half of my life I have been using and programming computers; the thought-processes and analytical style used in computer programming come naturally to me. I have considerable practical experience with a variety of languages, operating systems, hardware platforms and networks, and I have been employed as a consultant and a programmer by universities and businesses. As a youngster, I spent my time writing editors, designing operating systems, and developing new programming languages. Fifteen of my programs have been distributed over the Internet, complete with extensive documentation and commented source code. In 1984 , after graduating from Williams college , I was hired as a consultant by the User Services division of the University Computing Center of the University of Rochester . I was responsible for answering questions concerning the VAX/VMS system from the entire campus and the associated Strong Memorial Hospital, from students, faculty, staff, doctors and medical researchers. I taught computer-related minicourses from introductory to advanced levels, and wrote on-line and printed documentation for a variety of software products. At the end of my first year as a consultant, I was promoted to
