Recent technological improvement in character animation has increased the number of characters that can appear in a virtual scene. Besides, skeletal and mesh structures are expected to be more complex in the future. Therefore, simulating massive characters ...
This work is dedicated to the study of Dynamical Systems, depending on a slowly varying parameter. It contains, in particular, a detailed analysis of memory effects, such as hysteresis, which frequently appear in systems involving several time scales. In a ...
In networked virtual environments (NVEs), users are represented by their virtual embodiments. The articulated structure of these embodiments introduces a new complexity in the representation and streaming of animations, especially when the number of partic ...
We have designed a mobile -PDA-based- interface for real-time control of virtual characters in multiuser semi-immersive virtual environments - using a large rear-projection screen. The proof-of-concept implementation we present shows the potential of handh ...
Three-dimensional (3-D) motion estimation is applied to the problem of motion compensation for video coding. We suppose that the video sequence consists of the perspective projections of a collection of rigid bodies which undergo a rototranslational motion ...
This paper describes the implementation and modelling of a biologically inspired collective behaviour. The experiments are concerned with the gathering and clustering of randomly distributed small cylinders. Each experiment has been repeated ten times in a ...
Virtual reality is gaining on importance in many fields – scientific simulation, training, therapy and also more and more in entertainment. All these applications require the human user to interact with virtual worlds inhabited by intelligent characters an ...
We describe an approach to construct interactive virtual environments, which are suitable for the development of artificial virtual human life simulations. Our main goal is to have virtual human actors living and working autonomously in virtual environment ...
This paper presents a novel method of collaborative problem solving for intelligent agents in virtual environments. We describe a planner for STRIPS-like domains enhanced by techniques of "delegated computing". Instead of having one central planner with co ...
After implementing a motivational model of action selection applied to autonomous virtual humans inspired by models of animals' decision-making, the problem consists of testing it in good conditions for validation. Indeed this model has to respect the six ...
