A Facial Repertoire for Animation
(Eurographics Association, 2000)
Character design and facial animation of characters is among the most tedious parts of creation of animations. In contrast to body animations, performer data have not been successfully used for faces. The CharToon system ...
Spreading of the cultural heritage by means of multi-configurable, low cost virtual reality techniques
(Eurographics Association, 2000)
In the last few years, computer graphics techniques have been applied to preserve and promote the cultural heritage. In this first steps the bottleneck of these applications developed was the price of the hardware that ...
Robust Polygons Clipping to Model Complex Objects
(Eurographics Association, 2000)
One of the most important problems to solve in Solids Modelling is computing the boolean operations for solids (union, intersection and difference). In order to implement these three operations an algorithm to compute the ...
Virtual Humans: Ten Problems Still Not Completely Solved
(Eurographics Association, 2000)
During the 1980s, the academic establishment paid only scant attention to research on the animation of virtual humans. Today, however, almost every graphics journal, popular magazine, or newspaper devotes some space to ...
Combining finite element deformation with cutting for surgery simulations
(Eurographics Association, 2000)
Interactive surgery simulations have conflicting requirements of speed and accuracy. In this paper we show how to combine a relatively accurate deformation model—the Finite Element (FE) method—and interactive cutting without ...
Principles of Computer Graphics: the experience of a class A user
(Eurographics Association, 2000)
Computer graphics has gone a long way from the early days in the 50’s and 60’s. Today we have the web, and it’s all visual that is the fashion. What does an unsuspecting user of computers, who is not a specialist, actually ...
Volumetric Textures
(Eurographics Association, 2000)
There are some types of nature elements that are adequately represented in Computer Graphics only through volumes. In order to visualize scenes with volumes, together with geometrical objects, it is necessary to make use ...
Adding a scalar value to 2D vector field visualization: the BLIC (Bumped LIC)
(Eurographics Association, 2000)
Visualization of vector data produced from application areas such as computational fluid dynamics (CFD), environmental sciences, and material engineering is a challenging task. Texture-based methods reveal to be effective, ...
An Image Processing Approach to Detection of Ridges and Ravines on Polygonal Surfaces
(Eurographics Association, 2000)
Surface creases, ridges and ravines, provide us with important information about the shapes of 3D objects and can be intuitively defined as curves on a surface along which the surface bends sharply. Exploring similarity ...
