Interactive Image-Guided Modeling of Extruded Shapes
A recent trend in interactive modeling of 3D shapes from a single image is designing minimal interfaces, and
accompanying algorithms, for modeling a specific class of objects. Expanding upon the range of shapes that
existing minimal interfaces can model, we present an interactive image-guided tool for modeling shapes made up
of extruded parts. An extruded part is represented by extruding a closed planar curve, called base, in the direction
orthogonal to the base. To model each extruded part, the user only needs to sketch the projected base shape in the
image. The main technical contribution is a novel optimization-based approach for recovering the 3D normal of
the base of an extruded object by exploring both geometric regularity of the sketched curve and image contents.
We developed a convenient interface for modeling multi-part shapes and a method for optimizing the relative
placement of the parts. Our tool is validated using synthetic data and tested on real-world images.
