GPU-Based Hierarchical Texture Decompression
(The Eurographics Association, 2006)We propose a hierarchical texture compression algorithm for real-time decompression on the GPU. Our algorithm is characterized by low computational complexity, random access and hierarchical structure which allow us to ... -
Harnessing the Human Visual System for Image Based Modeling: an Interaction System
(The Eurographics Association, 2006)We present a novel interaction system for modeling 3D geometry from photographs. Given a set of stereo pairs, along with their camera parameters, the interface tracks the movements of the users and allows them to intuitively ... -
High Quality Shadows for Real-Time Crowds
(The Eurographics Association, 2006)Real-time shadowed crowds, especially under locally lit environments, pose several distinct challenges. Current solutions for crowds are either very simplistic for multiple lights or only handle a single directional light ... -
HOPI: A Novel High Order Parametric Interpolation in 2D
(The Eurographics Association, 2006)This paper presents a novel smooth and convergent high order parametric interpolation method called HOPI with a formal treatment. It employs high order derivatives information and provides more freedom on control of curves. ... -
Lighting-Up Geometry: Accurate 3D Modelling of Museum Artifacts with a Torch and a Camera
(The Eurographics Association, 2006)This paper addresses the problem of obtaining complete, very detailed reconstructions of shiny objects such as glazed ceramics. We present an algorithm which uses silhouettes of the object, as well as images obtained under ... -
m-LOMA - a Mobile 3D Portal to Location-based Information
(The Eurographics Association, 2006)We present a novel application, a mobile 3D city map, with a capability to render dozens of textured buildings at interactive rates in desktop machines, PDA devices and mart phones. The system allows annotation of the ... -
Magical Mirrors
(The Eurographics Association, 2006)This article describes the multi-media art installation MAGICAL MIRRORS with which the tradition of the mirror, as a medium of visual simulation, is carried over into the world of digital mediums. As theoretical framework, ... -
Modeling Autumn Sceneries
(The Eurographics Association, 2006)This paper presents a system for modeling autumn leaves covering vegetation and monuments. We simulate the coloring and aging process by a stochastic model that represents the probability of evolution of a leaf according ... -
Modeling Real-time Rendering
(The Eurographics Association, 2006)The real-time rendering process is well known to be extremely dynamic and complex. This paper presents a novel approach to modeling this process via the system identification methodology. Given the process s dynamic nature ... -
Multiresolution GPU Mesh Painting
(The Eurographics Association, 2006)Mesh painting is a well accepted and very intuitive metaphor for adding high-resolution detail to a given 3D model: Using a brush interface, the designer simply paints fine-scale texture or geometry information onto the ... -
A Perceptual Approach to Texture Scaling based on Human Computer Interaction
(The Eurographics Association, 2006)The trade-off between texture quality and data size is often an important factor for online multimedia applications including 3D games, virtual reality, as well as for applications designed for portable devices. Although ... -
Rapid Interactive Modelling from Video with Graph Cuts
(The Eurographics Association, 2006)We present a method for generating a parameterised model of a scene from a set of images. The method is novel in that it uses information from several sources video, sparse 3D points and user input to fit models to a scene. ... -
Rapid Modeling of Complex Building Façades
(The Eurographics Association, 2006)Architectural settings occur in many virtual environments. Modeling such highly detailed structures manually is a time-consuming and tedious task. Therefore we propose a system for the rapid modeling of building façades. ... -
Real-time Reflection using Ray Tracing with Geometry Field
(The Eurographics Association, 2006)A novel method for accurate reflections in real time is introduced using ray tracing in geometry fields, which combine light fields with geometry images. The geometry field of a surface is defined ray space, mapping a ray ... -
Real-time Soft Shadows with Shadow Accumulation
(The Eurographics Association, 2006)This paper presents a physically plausible soft-shadow algorithm that can be executed real-time by current GPUs. The method works with a single shadow map, requires no pre- or post-processing, and can also handle self ... -
Shape From Silhouette: Towards a Solution for Partial Visibility Problem
(The Eurographics Association, 2006)Acquiring human shape is a prerequisite to many applications in augmented and virtual reality, as well as in computer graphics and animation. The acquisition of a real person must be precise enough to have the best possible ... -
Similar Motion Retrieval for Dynamic 3D Mesh Based on Modified Shape Distributions
(The Eurographics Association, 2006)A similar motion search and retrieval system for dynamic 3D mesh is presented based on a modified shape distribution algorithm. In this paper, three fundamental functions for efficient retrieval have been developed: feature ... -
Simulating Drilling on Tetrahedral Meshes
(The Eurographics Association, 2006)Bone drilling is a fundamental task in several surgical procedures, including mastoidectomy, cochlear implantation, orbital surgery. It consists in eroding the part of the bone in contact with the tip of the surgical tool ... -
Solving Local Reflections: a Direct Methodology
(The Eurographics Association, 2006)Reflection and refraction are key processes intended for realism within simulation platforms. There are several parameters related to those techniques whose values have been traditionally selected by using subjective ...
