—This paper presents an integral system capable of generating animations with realistic dynamics, including the individualized nuances, of three-dimensional (3-D) human faces driven by speech acoustics. The system is capable of capturing short phenomena in the orofacial dynamics of a given speaker by tracking the 3-D location of various MPEG-4 facial points… (More)
This paper describes a technique for animating in real time garments placed over an articulated character. In order to do this, the character to be dressed must be approximated using a hierarchy of ellipsoids. The pieces of clothing are represented using mass-spring particle systems. First the particles move following the ellipsoids; this is followed by the… (More)
The ESTIA project aims to provide the means for mass adoption of Business-to-Consumer (B2C) E-Commerce in the tourism sector. Its main objective is to exploit emerging infrastructures and access devices, and develop advanced applications in order to provide innovative services to all parties involved in the Tourism sector with emphasis on tourists and SME… (More)
INTRODUCTION The internal jugular vein locates anterior or anterolateral to the common carotid artery in two-thirds of the subjects studied by ultrasound when the head is in a rotated position. AIM To identify variables associated with the anterior location of the internal jugular vein. METHODS Ultrasound examinations were performed with the patients in… (More)
A virtual environment application, including a clothed human as an avatar, is being developed. In this article we describe the overall application, how the real-time clothing simulation module was implemented as well as the technical issues that had to be solved for integration into a VR application.
