Irregular triangle meshes are a powerful digital shape representation: they are flexible and can represent virtually any complex shape; they are efficiently rendered by graphics hardware; they are the standard output of 3D acquisition and routinely used as input to simulation software. Yet irregular meshes are difficult to model and edit because they lack a higher-level control mechanism. In this talk, I will survey a series of research results on surface modeling via mesh deformation and show how high-resolution meshes can be interactively manipulated and animated in a fast and intuitive manner. I will also discuss how the incorporation of some simple physics laws directly into the interactive modeling framework can be done inexpensively and beneficially for geometric modeling: while not being as restrictive and parameter-heavy as a full-blown physical simulation, this allows to creatively model shapes with improved realism and directly use them in fabrication.
