Object orientation and concurrency are inherent to computer animation. Since the pieces of an animation can come from various media such as computer-generated imagery, video, and sound, the case for object orientation is all the stronger. However, languages for expressing the temporal coordination of animated objects have been slow in coming. We present such a language in this paper. Since the ...

A sampled object representation (SOR) defines a graphical model using data obtained from a sampling process, which takes a collection of samples at discrete positions in space in order to capture certain geometrical and physical properties of one or more objects of interest. Examples of SORs include images, videos, volume datasets and point datasets. Unlike many commonly used data representatio...

Facial animation has a lengthy history in computer graphics. To date, most efforts have concentrated either on labor-intensive keyframe schemes, on manually animated parameterized methods using FACS-inspired expression control schemes, or on performance-based animation where facial motions are captured from human actors. As an alternative, we propose the fully automated animation of faces using...

Currently, computer-animation programs are frequently used to instruct and stimulate young children in performing maximal expiratory flow/volume (MEFV) curves. The reproducibility and maximal performance of MEFV manoeuvres with and without the use of two computer-animation programs (the "candles" and the "balloon" programs) were evaluated. Eighty-eight children, aged 4-8 yrs, were randomly assi...

We present a new highly interactive computer animation tool to increase the mathematical skills of deaf children. We aim at increasing the effectiveness of (hearing) parents in teaching arithmetic to their deaf children, and the opportunity of deaf children to learn arithmetic via interactive media. Using state-ofthe-art computer animation technology we have designed and modeled three 3-dimensi...

This project aims to review existing approaches to animate in real time the facial features of a virtual character. We investigate a tool that will be usable for artists in live performances or to facilitate the creation of animation movies thanks to a quick preview of the results. The animation data are obtained by facial motion capture instrumentation (marker-based or markerless) or are gener...

Speech animation synthesis is still a challenging topic in the field of computer graphics. Despite many challenges, representing detailed appearance of inner mouth such as nipping tongue’s tip with teeth and tongue’s back hasn’t been achieved in the resulting animation. To solve this problem, we propose a method of data-driven speech animation synthesis especially when focusing on the inside of...

Facial animation has been combined with text-to-speech synthesis to create innovative multimodal interfaces. In this paper, we present an architecture for this multimodal interface. A face model is downloaded from a server into a client. The client uses an MPEG-4 compliant speech synthesizer that animates the head. The server sends text and animation data to the client in addition to regular co...

As 3D computer animation becomes more accessible to novice users, it makes it possible for these users to create high-quality animations. This paper introduces a more powerful system to create highly articulated character animations with an intuitive setup then the previous research, Spatial Keyframing. As the main purpose of Spatial Keyframing was the rapid generation of primitive animation ov...
