 Summary

Current graphics cards (GPUs) shade small polygons inefficiently. When surfaces are represented using micropolygons of less than a pixel in size, many shading computations performed by a GPU are redundant. Since shading is typically the most expensive operation in a graphics pipeline, this leads to poor rendering performance. This thesis presents a prototype implementation of quadfragment merging, which reduces redundant shading work by buffering and selectively merging rasterized fragments prior to shading. The prototype quadfragment merger is described in detail, and evidence is presented that it is amenable to implementation in fixedfunction hardware. Performance results indicate that our implementation decreases shader executions by a factor of eight when rendering micropolygons, and effectively makes use of a number of optimizations to yield high performance. Finally, an early prototype of a corollary technique that shades scenes with motion blur is described, and preliminary results are presented.

 Summary

Verdict is a collection of subroutines for evaluating the geometric qualities of triangles, quadrilaterals, tetrahedra, and hexahedra using a variety of metrics. A metric is a real number assigned to one of these shapes depending on its particular vertex coordinates. These metrics are used to evaluate the input to finite element, finite volume, boundary element, and other types of solvers that approximate the solution to partial differential equations defined over regions of space. The geometric qualities of these regions is usually strongly tied to the accuracy these solvers are able to obtain in their approximations. The subroutines are written in C++ and have a simple C interface. Each metric may be evaluated individually or in combination. When multiple metrics are evaluated at once, they share common calculations to lower the cost of the evaluation.

 Summary

The Common Geometry Module (CGM) is a code library which provides geometry functionality used for mesh generation and other applications. This functionality includes that commonly found in solid modeling engines, like geometry creation, query and modification; CGM also includes capabilities not commonly found in solid modeling engines, like geometry decomposition tools and support for shared material interfaces. CGM is built upon the ACIS solid modeling engine, but also includes geometry capability developed beside and on top of ACIS. CGM can be used asis to provide geometry functionality for codes needing this capability. However, CGM can also be extended using derived classes in C++, allowing the geometric model to serve as the basis for other applications, for example mesh generation. CGM is supported on Sun Solaris, SGI, HP, IBM, DEC, Linux and Windows NT platforms. CGM also includes support for loading ACIS models on parallel computers, using MPIbased communication. Future plans for CGM are to port it to different solid modeling engines, including Pro/Engineer or SolidWorks. CGM is being released into the public domain under an LGPL license; the ACISbased engine is available to ACIS licensees on request.

 Description
 Book — xi, 255 p. : col. ill. ; 27 cm.
 Summary

Discrete geometry is a relatively new development in pure mathematics, while computational geometry is an emerging area in applicationsdriven computer science. Their intermingling has yielded exciting advances in recent years, yet what has been lacking until now is an undergraduate textbook that bridges the gap between the two. Discrete and Computational Geometry offers a comprehensive yet accessible introduction to this cuttingedge frontier of mathematics and computer science. This book covers traditional topics such as convex hulls, triangulations, and Voronoi diagrams, as well as more recent subjects like pseudotriangulations, curve reconstruction, and locked chains. It also touches on more advanced material, including Dehn invariants, associahedra, quasigeodesics, Morse theory, and the recent resolution of the Poincare conjecture. Connections to realworld applications are made throughout, and algorithms are presented independently of any programming language. This richly illustrated textbook also features numerous exercises and unsolved problems. The essential introduction to discrete and computational geometry Covers traditional topics as well as new and advanced material Features numerous fullcolor illustrations, exercises, and unsolved problems Suitable for sophomores in mathematics, computer science, engineering, or physics Rigorous but accessible An online solutions manual is available (for teachers only). To obtain access, please email: Vickie_Kearn@press.princeton.edu.

 Summary

This anthology is based on the First ACM Workshop on Applied Computational Geometry, WACG '96, held in Philadelphia, PA, USA, in May 1996, as part of the FCRC Conference.Today, CG is in transition and applied computational geometry has established itself as a fertile meeting ground for theorists from core computational geometry and practitioners from the potential application areas to exchange their ideas and identify issues of common interest. The book presents 11 invited contributions and stateoftheart reports by leading experts together with 12 refereed full papers selected from 32 submissions. It points the way towards geometrical engineering and addresses researchers and professionals sharing an interest in geometric algorithms and techniques and their use in computational sciences and engineering.

 Description
 Book — xvii, 393 p. : ill. ; 24 cm.
 Summary

Often a solution to a problem lies simply in uncovering its correct description. It is this underlying concept that consolidates the text of this survey of geometric ideas. The aim of this book is to provide a way in which to visualize a variety of geometric problems and present the tools for their accurate representation. Disassociating fundamental ideas and methods from special applications, they clarify these concepts for the reader and allow for applying the material to other problems of a geometric nature. They also provide a foundation of applied geometry as used in geometric design and geometric modelling.
