Robust Motion Watermarking based on Multiresolution Analysis
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Digital watermarking is one of commonly used solutions for copyright protection. A watermark should be imperceptible and robust to various attacks. In this paper, we address watermarking for motion data. Our watermarking ... -
Using an Intermediate Skeleton and Inverse Kinematics for Motion Retargeting
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we present a new method for solving the Motion Retargeting Problem, by using an intermediate skeleton. This allows us to convert movements between hierarchically and geometrically different characters. An ... -
Priority-Driven Acoustic Modeling for Virtual Environments
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Geometric acoustic modeling systems spatialize sounds according to reverberation paths from a sound source to a receiver to give an auditory impression of a virtual 3D environment. These systems are useful for concert hall ... -
Haptic Cues for Image Disambiguation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Haptic interfaces represent a revolution in human computer interface technology since they make it possible for users to touch and manipulate virtual objects. In this work we describe a cross-model interaction experiment ... -
External Memory View-Dependent Simplification
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we propose a novel external-memory algorithm to support view-dependent simplification for datasets much larger than main memory. In the preprocessing phase, we use a new spanned sub-meshes simplification ... -
Subdivision Surface Tesselation on the Fly using a versatile Mesh Data Structure
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Subdivision surfaces have become a standard technique for freeform shape modeling. They are intuitive to use and permit designers to flexibly add detail. But with larger control meshes, efficient adaptive rendering techniques ... -
Augmented Reality with Back-Projection Systems using Transflective Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we introduce the concept of Extended VR (extending viewing space and interaction space of back-projection VR systems), by describing the use of a hand-held semi-transparent mirror to support augmented reality ... -
Interpolatory ?3-Subdivision
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a new interpolatory subdivision scheme for triangle meshes. Instead of splitting each edge and performing a 1-to-4 split for every triangle we compute a new vertex for every triangle and retriangulate the old ... -
Real Time, Accurate, Multi-Featured Rendering of Bump Mapped Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a new technique to render in real time objects which have part of their high frequency geometric detail encoded in bump maps. It is based on the quantization of normal-maps, and achieves excellent result both ... -
Physically-Based Patination for Underground Objects
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Although current photorealistic rendering techniques can produce very impressive images, the rendered objects are often too clean and shiny. Thus, the resulting images look unnatural. This paper proposes a physically-based ... -
A Novel Approach Makes Higher Order Wavelets Really Efficient for Radiosity
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Since wavelets were introduced in the radiosity algorithm 5, surprisingly little research has been devoted to higher order wavelets and their use in radiosity algorithms. A previous study 13 has shown that wavelet radiosity, ... -
Scene-Graph-As-Bus: Collaboration between Heterogeneous Stand-alone 3-D Graphical Applications
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We describe the Scene-Graph-As-Bus technique (SGAB), the first step in a staircase of solutions for sharing software components for virtual environments. The goals of SGAB are to allow, with minimal effort, independently-designed ... -
Generating Animatable 3D Virtual Humans from Photographs
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present an easy, practical and efficient full body cloning methodology. This system utilizes photos taken from the front, side and back of a person in any given imaging environment without requiring a special background ...
