L-Systems and Artificial Chemistry to Develop Digital Organisms

Abstract

With the purpose of populating virtual worlds with various adapted artificial organisms, we propose an ontogenetic and phylogenetic hybrid model to generate complete organisms possessing metabolism, morphology, and behavior from a single initial cell. The initial purpose of our work is to generate organisms that are thereafter used to define complete organisms. In this paper, we introduce a bioinspired cellular developmental model that links different approaches of ontogenesis systems: grammatical and cell chemistry approaches. Thus, we propose an alternative to parametric L-systems (APL-systems) in order to simulate morphogenesis of organisms according to their internal states. The developed organisms have a metabolism using environmental substrates to grow and to act. Moreover, they are able to exhibit almost perfect self-healing characteristics afterwards or even during their development
