Anisotropic Filtering of Non-Linear Surface Features
(The Eurographics Association and Blackwell Publishing, Inc, 2004)A new method for noise removal of arbitrary surfaces meshes is presented which focuses on the preservation and sharpening of non-linear geometric features such as curved surface regions and feature lines. Our method uses ... -
Applied Geometry:Discrete Differential Calculus for Graphics
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Geometry has been extensively studied for centuries, almost exclusively from a differential point of view. However, with the advent of the digital age, the interest directed to smooth surfaces has now partially shifted due ... -
Approximate Soft Shadows win an Image-Space Flood-Fill Algorithm
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Most former soft shadow algorithms have either suffered from restricted self-shadowing capabilities, been too slow for interactive applications, or could only be used with a limited types of geometry. In this paper, we ... -
Approximated Centroidal Voronoi Diagrams for Uniform Polygonal Mesh Coarsening
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present a novel clustering algorithm for polygonal meshes which approximates a Centroidal Voronoi Diagram construction. The clustering provides an efficient way to construct uniform tessellations, and therefore leads ... -
Approximation of Optimal Voxel Size for Collision Detection in Maintainability Simulations within Massive Virtual Environments
(The Eurographics Association and Blackwell Publishing Ltd., 2004)This paper describes a Collision Method for massive virtual environments composed of millions of triangles. It has been applied in the aeronautics industry for maintainability simulations using virtual aircraft engine ... -

Balancing Considered Harmful - Faster Photon Mapping using the Voxel Volume Heuristic -
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Photon mapping is one of the most important algorithms for computing global illumination. Especially for efficiently producing convincing caustics, there are no real alternatives to photon mapping. On the other hand, photon ... -
A Biophysically-Based Spectral Model of Light Interaction with Human Skin
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Despite the notable progress in physically-based rendering, there is still a long way to go before we can automatically generate predictable images of biological materials. In this paper, we address an open problem in this ... -

Coherent Hierarchical Culling: Hardware Occlusion Queries Made Useful
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present a simple but powerful algorithm for optimizing the usage of hardware occlusion queries in arbitrary complex scenes. Our method minimizes the number of issued queries and reduces the delays due to the latency of ... -
Combined Correlated and Importance Sampling in Direct Light Source Computation and Environment Mapping
(The Eurographics Association and Blackwell Publishing, Inc, 2004)This paper presents a general variance reduction method that is a quasi-optimal combination of correlated and importance sampling. The weights of the combination are selected automatically in order to keep the merits of ... -
Compression of Large-Scale Terrain Data for Real-Time Visualization Using a Tiled Quad Tree
(The Eurographics Association and Blackwell Publishing Ltd., 2004)The aim of the rapid world modeling project is to implement a system to visualize the topography of the entire world on consumer-level hardware. This presents a significant problem in terms of both storage requirements and ... -

Computing Maximal Tiles and Application to Impostor-Based Simplification
(The Eurographics Association and Blackwell Publishing, Inc, 2004)The computation of the largest planar region approximating a 3D object is an important problem with wide applications in modeling and rendering. Given a voxelization of the 3D object, we propose an efficient algorithm to ... -
Crowd of Virtual Humans: a New Approach for Real Time Navigation in Complex and Structured Environments
(The Eurographics Association and Blackwell Publishing, Inc, 2004)The navigation activity is an every day practice for any human being capable of locomotion. Our objective in this work is to reproduce this crucial human activity inside virtual environments. Putting together the high ... -
Cultural Heritage Preservation Using Constructive Shape Modeling
(The Eurographics Association and Blackwell Publishing Ltd., 2004)Issues of digital preservation of shapes and internal structures of historical cultural objects are discussed. An overview of existing approaches to digital preservation related to shape modeling is presented and corresponding ... -
Deferred Splatting
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In recent years it has been shown that, above a certain complexity, points become the most efficient rendering primitives. Although the programmability of the lastest graphics hardware allows efficient implementation of ...
