Preserving the Mental Map using Foresighted Layout
(The Eurographics Association, 2001)First we introduce the concept of graph animations as a sequence of evolving graphs and a generic algorithm which computes a Foresighted Layout for dynamically drawing these graphs while preserving the mental map. The ... -
Progressive View-Dependent Isosurface Propagation
(The Eurographics Association, 2001)This paper proposes a new isosurface extraction algorithm that extracts portions of the isosurface in a view-dependent manner by ray casting and propagation. The algorithm casts rays through a volume to find visible active ... -
The Rendering of Unstructured Grids Revisited
(The Eurographics Association, 2001)In this paper we propose a technique for resampling scalar fields given on unstructured tetrahedral grids. This technique takes advantage of hardware accelerated polygon rendering and 2D texture mapping and thus avoids any ... -
Salient Representation of Volume Data
(The Eurographics Association, 2001)We introduce a novel method for identification of objects of interest in volume data. Our approach conveys the information contained in two essentially different concepts, the object s boundaries and the narrow solid ... -
A Selective Refinement Approach for Computing the Distance Functions of Curves
(The Eurographics Association, 2001)We present an adaptive signed distance transform algorithm for curves in the plane. A hierarchy of bounding boxes is required for the input curves. We demonstrate the algorithm on the isocontours of a turbulence simulation. ... -
Space-Efficient Boundary Representation of Volumetric Objects
(The Eurographics Association, 2001)In this paper we present a compression technique for efficiently representing boundary objects from volumetric data-sets. Exploiting spatial coherency within object contours, we are able to reduce the size of the volumetric ... -
Stream Surface Generation for Fluid Flow Solutions on Curvilinear Grids
(The Eurographics Association, 2001)A stream surface in a steady-state three-dimensional fluid flow vector field is a surface across which there is no flow. Stream surfaces can be useful for visualization because the amount of data presented in one visualization ... -
Subdivision Surfaces for Scattered-data Approximation
(The Eurographics Association, 2001)We propose a modified Loop subdivision surface scheme for the approximation of scattered data in the plane. Starting with a triangulated set of scattered data with associated function values, our scheme applies linear, ... -
Three-dimensional Reconstruction and Visualization of the Cerebral Cortex in Primates
(The Eurographics Association, 2001)We present a prototype interactive application for the direct analysis in three dimensions of the cerebral cortex in primates. The paper provides an overview of the current prototype system and presents the techniques used ... -
Topology-Based Visualization of Time-Dependent 2D Vector Fields
(The Eurographics Association, 2001)Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ... -
Vector and Tensor Field Topology Simplification on Irregular Grids
(The Eurographics Association, 2001)Topology-based visualization of planar turbulent flows results in visual clutter due to the presence of numerous features of very small scale. In this paper, we attack this problem with a topology simplification method for ... -
Virtual Colon Flattening
(The Eurographics Association, 2001)We present a new method to visualize virtual endoscopic views. We propose to flatten the organ by the direct projection of the surface onto a set of cylinders. Two sampling strategies are presented and the introduced ... -
Visualization of directed associations in e-commerce transaction data
(The Eurographics Association, 2001)Many real-world e-commerce applications require the mining of large volumes of transaction data to extract marketing and sales information. This paper describes the Directed Association Visualization (DAV) system that ... -
Visualization of Generalized Voronoi Diagrams
(The Eurographics Association, 2001)Voronoi diagrams are an important data structure in computer science. However well studied mathematically, understanding such diagrams for different metrics, orders, and site shapes is a complex task. We propose a new ... -
Visualization of Thermal Flows in an Automotive Cabin with Volume Rendering Method
(The Eurographics Association, 2001)A predictive system of thermal flow with quick turnaround time in a passenger compartment has been developed. An efficient method based on the Cartesian mesh system was used to reduce the period of analysis. The computed ... -
Volume Rendering Data with Uncertainty Information
(The Eurographics Association, 2001)This paper explores two general methods for incorporating volumetric uncertainty information in direct volume rendering. The goal is to produce volume rendered images that depict regions of high (or low) uncertainty in the ... -
Voxel Column Culling: Occlusion Culling for Large Terrain Models
(The Eurographics Association, 2001)We present Voxel Column Culling, an occlusion culling algorithm for real-time rendering of large terrain models. This technique can greatly reduce the number of polygons that must be rendered every frame, allowing a larger ...
