Parallel Visibility Test and Occlusion Culling in Avango Virtual Environment Framework
(Eurographics Association, 2003)
Real-time visibility test is an attractive feature for Virtual Environment (VE) applications where large datasets should be interactively explored. In such scenes most of the objects are usually occluded by other ones, and ...
Lip-Synching in Sourdough
(Eurographics Association, 2003)
This animation relates the story of a seemingly sweet doughy spokesman that has now gone sour. Through his crusty demeanor and somewhat greasy antics, our hero discovers that if you try to have your cake and eat it too, ...
VR Game Interfaces for Interaction onto 3D Display
(Eurographics Association, 2003)
This paper describes the VR game interfaces for interaction onto 3D display. The challenge we are interested in is how to build and use a low cost 3D display that satisfies semi-immersive requirements and how to coordinate ...
Alternative Augmented Reality Approaches: Concepts, Techniques, and Applications
(Eurographics Association, 2003)
In this tutorial we discuss application specific alternative augmented reality (AR) approaches –such as Virtual Showcases and Shader Lamps– that focus on overcoming some of the limitations linked to conventional AR displays. ...
Trans-Polygon Stroke Method for Frame Coherent Pastel Images
(Eurographics Association, 2003)
We propose Trans-Polygon Stroke Method (TPSM) for creating pastel-like animation that keeps frame-to-frame coherence. There are several variable factors in hand-drawn pastel such as paper roughness and pigments. When these ...
Real time positioning system based on active stereo and facial features identification
(Eurographics Association, 2003)
We propose a new system for patient’s head positioning for radiology and radiotherapy. The system is constituted of two low-cost digital cameras and a digital projector. As a first step a bright pattern is projected onto ...
Fast Marching farthest point sampling
(Eurographics Association, 2003)
We introduce the Fast Marching farthest point sampling (FastFPS) approach for the progressive sampling of planar domains and curved manifolds in triangulated, point cloud or implicit form. By using Fast Marching methods2, ...
Interactive demo: OpenGLfly, version Euskadi
(Eurographics Association, 2003)
This paper describes the demo associated to one of our projects, which is currently under development. The version presented can be considered as a large terrain simulation over the Basque Country area (North of Spain), ...
A Framework for Video-based and Hardware-Accelerated Remote 3D-Visualization
(Eurographics Association, 2003)
This paper presents a framework for video-based and hardware-accelerated remote 3d-visualization that produces and delivers high quality video streams at an accurate frame rate. The framework is based on the portable ...
Large XML Document Manager and Visualizer
(Eurographics Association, 2003)
This work presents an interactive Graphical User Interface used to display and manipulate collection of large XML documents. It relies on a geometrical model that combines hierarchical and sequential representations. In ...
