    Inferring 3D free-form shapes from contour drawings


    We aim to create a simple intuitive interface allowing a user to model three-dimensional shapes by sketching them on a computer screen. Based on a contour drawing of some object, the system creates a 3D model that matches the given contour and is one of the plausible interpretations of the drawing. Current 3D modeling software tools like Maya are powerful but hard to learn; they’re not very well suited for initial conceptual de- sign except perhaps by experts. A sketch-based free-form modeling interface like Teddy [Igarashi et al. 1999] is simpler and more intuitive, but is limited: the input must consist of simple closed curves.
