Experimenting Prioritized IK for Motion Editing
(Eurographics Association, 2003)
The presented work illustrates the potential of an IK algorithm enforcing priorities among constraints for motion editing. Motion capture is a very efficient technique to deliver believable motions but usually most of the ...
Virtual Endoscopy in Research and Clinical Practice
(Eurographics Association, 2003)
Virtual endoscopy is among the most active topics in virtual medicine and medical imaging. It focuses on the virtual representation of minimally invasive procedures for training, planning, and diagnosis without an actual ...
Parametric Foveation for Progressive Texture and Model Transmission
(Eurographics Association, 2003)
Spatially varying sensing (foveation) has been used in many different areas of Computer Vision, such as image compression and video teleconferencing and in perceptually driven Level of Detail (LOD) representations in ...
Predictive fixed-frame rate tessellation of NURBS surfaces
(Eurographics Association, 2003)
In this work we propose a predictive fixed-frame rate scheme that shows how to control the visualization frame rate using uniform dynamic tessellation. Similar to previous works5; 6, tessellation quality criteria is based ...
Animating Tree Movement with Sound Effects Generation
(Eurographics Association, 2003)
This video demonstrates the methods for automatically generating tree motions and sound effects for an animation of branches and leaves moving in the wind. Natural motions of leaves and branches swaying in a wind field are ...
A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes
(Eurographics Association, 2003)
We present a spatial representation based on a hierarchical structure using the well-known spatial indexing structure called octree. There are very useful spatial representations for scenes whose objects can be distributed ...
VelvetPath - Layout Design System with Sketch and Paint Manipulations
(Eurographics Association, 2003)
We describe the VelvetPath system, a system that allows users to design layouts for visualized information by using sketch and paint manipulations. Many systems enable users to visually search and browse through information ...
Multi-resolution modelling of terrains by using non restricted quadtree triangulation
(Eurographics Association, 2003)
The interactive visualization of terrains requires the processing of a high amount of data in real time, usually it is not possible to work with all of them on main in memory. In this work we present, a method which solves ...
On the characterization of avatars in Distributed Virtual Worlds
(Eurographics Association, 2003)
Current Distributed Virtual Environment (DVE) systems run simulations based on a server-network architecture, where the population of avatars should be properly assigned to the servers in the DVE. This goal, called ...
Facial Modeling and Animation
(Eurographics Association, 2003)
In this tutorial we present an overview of the concepts and current techniques that have been developed to model and animate human faces. We introduce the research area of facial modeling and animation by its history and ...
