Parallelizing the ZSWEEP Algorithm for Distributed-Shared Memory Architectureschines, and study its performance on three generations of SGI multiprocessors, including the new Origin 3000 series..The main idea of the ZSWEEP algorithm is very simple; it is based on sweeping the data with a plane parallel to the viewing plane, in order of increasing ., projecting the faces of ce

Visualization of Labeled Segments Cross-Contour Surfacesres in parallel image slices of volume models. They are also suitable for the representation of CAD objects with tubular elongated shapes such as pipes and tools. Rendering these surfaces consists of tiling between successive contours, which is mainly a problem of establishing correspondences: betwe

Topology-Guided Downsamplingng methods by preferably selecting scalar values of critical points. In particular, many critical points can be preserved which are lost by traditional downsampling methods. Our method is named “topology-guided downsampling” as topology-preserving downsampling is impossible in general. However, we s

This year‘s event was the second in the series, following a successful premiere in Swansea, Wales, in March 1999, and was co-sponsored by the IEEE Technical Committee on Visualization and Graphics (TC-VG) as well as EUROGRAPHICS. The Volume Graphics Workshop is held bi-annually and ha

Volume Graphics Modeling of Ice Thawing visual effect as physically-based models, without highly-complex computations. This paper focuses on ice thawing as a quite common phenomenon in our daily life, and presents volume modeling of the phenomenon using mathematical morphology and cellular automaton.

Refraction in Discrete Ray Tracingields as well as volumetric datasets. In particular, the study shows that the normal estimation plays a critical role in synthesizing aesthetically pleasing images. The paper also includes the results of various tests, and our quantitative and qualitative analysis.

A Study of Transfer Function Generation for Time-Varying Volume Datacharacteristics were used for our study. Results obtained using two different classes of methods are discussed, along with lessons learned. These methods, including a new multi-resolution opacity map approach, can be used for semi-automatic generation of transfer functions to explore large-scale time-varying data sets.
