Deferred, Self-Organizing BSP Trees
(Blackwell Publishers, Inc and the Eurographics Association, 2002)bsptrees and KD trees are fundamental data structures for collision detection in walkthrough environments. A basic issue in the construction of these hierarchical data structures is the choice of cutting planes. Rather ... -
Designing 2D Vector Fields of Arbitrary Topology
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We introduce a scheme of control polygons to design topological skeletons for vector fields of arbitrary topology. Based on this we construct piecewise linear vector fields of exactly the topology specified by the control ... -
Dynamic Textures for Image-based Rendering of Fine-Scale 3D Structure and Animation of Non-rigid Motion
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The problem of capturing real world scenes and then accurately rendering them is particularly difficult for fine-scale 3D structure. Similarly, it is difficult to capture, model and animate non-rigid motion. We present a ... -
Efficient Fitting and Rendering of Large Scattered Data Sets Using Subdivision Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We present a method to efficiently construct and render a smooth surface for approximation of large functional scattered data. Using a subdivision surface framework and techniques from terrain rendering, the resulting ... -
Efficient Multidimensional Sampling
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Image synthesis often requires the Monte Carlo estimation of integrals. Based on a generalized concept of stratification we present an efficient sampling scheme that consistently outperforms previous techniques. This is ... -
Fast Continuous Collision Detection between Rigid Bodies
(Blackwell Publishers, Inc and the Eurographics Association, 2002)This paper introduces a fast continuous collision detection technique for polyhedral rigid bodies. As opposed to most collision detection techniques, the computation of the first contact time between two objects is inherently ... -
Flattening 3D objects using silhouettes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)An important research area in non-photorealistic rendering is the obtention of silhouettes. There are many methods to do this using 3D models and raster structures, but these are limited in their ability to create stylised ... -
Free-form sketching with variational implicit surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2002)With the advent of sketch-based methods for shape construction, there's a new degree of power available in the rapid creation of approximate shapes. Sketch [Zeleznik, 1996] showed how a gesture-based modeler could be used ... -
A Frequency-Domain Approach to Watermarking 3D Shapes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)This paper presents a robust watermarking algorithm with informed detection for 3D polygonal meshes. The algorithm is based on our previous algorithm [22] that employs mesh-spectral analysis to modify mesh shapes in their ... -
Geometric Approximations Towards Free Specular Comic Shading
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We extend the standard solution to comic rendering with a comic-style specular component. To minimise the computational overhead associated with this extension, we introduce two optimising approximations; the perspective ... -
Geometric Snakes for Triangular Meshes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Feature detection is important in various mesh processing techniques, such as mesh editing, mesh morphing, mesh compression, and mesh signal processing. In spite of much research in computer vision, automatic feature ... -
Grid Based Final Gather for Radiosity on Complex Clustered Scenes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Radiosity methods handle large scenes and complex objects using clustering techniques. To reconstruct a high quality image, usually a second very time consuming final gather pass is applied which exactly recomputes the ... -
Hardware Accelerated Interactive Vector Field Visualization: A level of detail approach
(Blackwell Publishers, Inc and the Eurographics Association, 2002)This paper presents an interactive global visualization technique for dense vector fields using levels of detail. We introduce a novel scheme which combines an error-controlled hierarchical approach and hardware acceleration ... -
Hardware-Based Volumetric Knit-Wear
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We present a hardware-based, volumetric approach for rendering knit wear at very interactive rates. A single stitch is represented by a volumetric texture with each voxel storing the main direction of the strands of yarn ... -
Hybrid Geometric - Image Based Rendering
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We present a Hybrid Geometric-Image Based Rendering (HGIBR) system for displaying very complex geometrical models at interactive frame rates. Our approach replaces distant geometry with a combination of image-based ... -
Image-Swept Volumes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Many graphical objects can be represented by swept volumes (including its subset - generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept ... -
Improved Scene Reconstruction from Range Images
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The modeling of real scenes is a complex and challenging task for which the use of laser rangefinders is one of the most promising approaches. Unfortunately, in many situations, it is not possible or practical to guarantee ... -
Interactive Visualization with Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2002)One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ... -
Intrinsic Parameterizations of Surface Meshes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Parameterization of discrete surfaces is a fundamental and widely-used operation in graphics, required, for instance, for texture mapping or remeshing. As 3D data becomes more and more detailed, there is an increased need ...
