This tutorial provides an intuitive connection between many standard 3D geometric concepts used in computer graphics and their higher-dimensional counterparts. We begin by answering frequently asked geometric questions whose resolution, though obvious in hindsight, may be obscure to those who have never ventured beyond the third dimension. We then develop methods for describing, transforming, i...

several nonpeptide small molecules were designed as potential inhibitors of hiv protease and their structures were constructed by computer-aided molecular modeling and docked iwo the active site of hiv protease. models of the complexes of inhibitors and the hiv protease were refined using nonbonded and h-bonding terms. the refined energy of selected complexes showed that the designed inhibitors...

With many new members joining the CG&A editorial board over the past year, and with a renewed commitment to not only document the state of the art in computer graphics research and applications but to anticipate and where possible foster future areas of scienti c discourse and industrial practice, we asked editorial and advisory council members about where they see their elds of expertise going...

In today’s world of interactive computer graphics applications the choice of graphics API is crucial, but still far from clear-cut. Especially when developing for consumer-level hardware the choice of API is very important, since it will have a tremendous impact on the potential market share, as well as performance and flexibility. Nevertheless, there is no single API that is definitely better ...

We propose a framework for developing online interactive experiments for training students to master the basic concepts of 3D Computer Graphics. As 3D Computer Graphics has applications in a large range of fields (visual arts, media, geography. etc.), we need to devote particular attention to students that are nonexperts in Computer Science and particularly in programming. We also have to take ...

To present and explore topics in computer graphics traditional teaching methodologies and tools are not sufficient. An approach is needed which provides students with an easy to use programming environment and which enables them to build their own interactive graphic applications. In this paper we present our experiences with the Java 3D API in a computer graphics course on modeling and simulat...

A virtual environment is an interactive, head-referenced computer display that gives a user the illusion of presence in a virtual world. Two most significant differences between a virtual environment and a more traditional interactive 3D computer graphics system are the extent of the user's sense of presence and the level of user participation that can be obtained in the virtual environment. Ov...

Arbitrary topology shape reconstruction from planar cross sections. of irregular meshes using diffusion and curvature flow. In SIGGRAPH '99: Proceedings of the 26th annual conference on Computer graphics and interactive techniques, pages 317–324, 1999.

Emphasis is an important vehicle to communicate relevance and to guide user focus, especially in interactive computer graphics. In dynamic 3D systems in particular, emphasis techniques must also consider visibility issues. This work discusses possible solutions and describes an implementation.

The OpenGL raster graphics API is well known amongst computer graphics programmers. However, while raster graphics dominates the interactive computer graphics industry, these systems are not able to produce scenes with the realism required by ventures such as the movie industry. For markets that require high levels of realism but not online generation of the scene, raytracing has become popular...
