While the use of digital models and simulation has already spread in many disciplines, recent advances in Computer Graphics open the way to a much lighter ways of creating 3D contents. In this talk, I’ll show how the expressive modeling paradigm - namely, the combination of graphical models embedding knowledge with gestural interfaces such as sketching, sculpting or copy-pasting - can allow seamless 3D modeling, progressive refinement, and animation of a variety of models, from individual shapes to full, animated 3D worlds. We discuss how prior knowledge can be enhanced by learning from examples, the later being possibly injected on the fly during a modeling session. As we show through examples, this methodology opens the way to seamless creation and interaction of scientists and engineers with the mental models of their object of study, in areas as different as soft products manufacturing, medicine, plants and ecosystem simulation, or geology.
