    Area, spline-based and structural models for generating and animating 3 D characters and logos (1985)
    Springer
    The visual computer 1 (1985), S. 15-23

    Notes: Abstract Various models and methods for generating three-dimensional texts and logos are reviewe. These methods are classified into area-modelled methods, surface methods and structural methods. Two innovative techniques are introduced. One is based on the propagation of polygons to generate beta-spline surfaces. The second is based on ruled surfaces which are generated with polygonal characters. Each method is illustrated by means of original examples. A methodology for creating animated logos is also illustrated with two examples.

    A “lifegame” approach to surface modeling and rendering (1986)
    Springer

    Notes: Abstract Conway's Lifegame is a trivial and wellknown application of a more general theory called the theory of cellular automata. Complex systems modeling may be based on the theory of cellular automata, originated by John von Neumann. Our approach is to define simple components that we call “analog automata”. An analog automaton is a finite state automaton where the state is defined in terms of real numbers representing physical quantities such a position, velocity, mass or color. Deterministic state transition function are applied to these automata using information from the state of neighboring automata. In our case, successive generations in the evolution of these cellular automata are mapped onto polygonal meshes in order to build and texture arbitrary surfaces.
