We study the use of the generative systems known as computational ecosystems to convey artistic and narrative aims. These are virtual worlds running on computers, composed of agents that trade units of energy and emulate cycles of life and behaviors adapted from biological life forms. In this article we propose a conceptual framework in order to understand(More)
DECLARATION I hereby declare that I composed this thesis entirely myself and that it describes my own research. 2 This research is an exploration of issues surrounding the artistic production of Computational Ecosystems. A Computational Ecosystem is a system of agents designed to emulate, in the computer, biological systems where autonomous individuals are(More)
In this paper a novel approach to a decentralized autonomous model of agency for general purpose Non-Player Characters (NPCs) is presented: the AI model of Computational Ecosystems. We describe the technology used to animate a population of gregarious humanoid avatars in a virtual world. This artistic work is an ethnographic project where a population of(More)
In this paper, we Secdescribe an agency model for generative populations of humanoid characters, based upon temporal variation of affective states. We have built on an existing agent framework from Sequeira et al. [18], and adapted it to be susceptible to temperamental and emotive states in the context of cooperative and non-cooperative interactions based(More)
In this paper, we examine virtual ecosystems as general-purpose authoring tools for heterogeneity and spontaneity, and discuss the use of such systems as animation drivers in a variety of contexts: from artistic abstract work, to dance choreographies, or even in the simulation of historical spaces. First, we present the background, motivation and summary(More)
xTNZ1, is focused on the exploration of the possibilities of using artificial life in the context of art. My aim is to develop an ecosystem based on a real-time three-dimensional PC based system sustaining a “living” virtual environment. The entities populating this virtual world have been designed to be active and responsive. They behave and interact with(More)
