This memoir for accreditation to supervise research deals with continuous models of computation. It is proven that plane geometry provides computation power. In the world of cellular automata, one often hears of particles or signals (that forms discrete lines on space-time diagrams), both for analyzing some dynamics and for conceiving particular cellular automata. The starting point of this work is to consider continuous counterparts of signals. We define a continuous model, \emph{signal machines}, that generates geometrical figures complying strict rules. This model can be understood as a continuous extension of cellular automata. The memoir begins with a brief introduction to cellular automata and signals, and a classification of models o...
