Abstract
Virtual Reality (VR) offers a promising platform for modeling man-made shapes by enabling immersive, hands-on interaction with these 3D shapes. Existing VR tools require either a complex user interface or a post-processing to model fabricable man-made shapes. In this paper, we present a VR tool that enables general users to interactively model man-made shapes for personalized fabrication, simply by using four common hand gestures as the interaction input. This is achieved by proposing an approach that models complex man-made shapes using a small set of geometric operations, and then designing a user interface that intuitively maps four common hand gestures to these operations. In our shape modeling approach, each shape part is modeled as a generalized cylinder with a specific shape type and iteratively assembled in a structure-aware manner to form a fabricable and usable man-made shape. In our user interface, each hand gesture is associated with a specific kind of interaction tasks and is intelligently utilized for performing the small set of operations to create, edit, and assemble generalized cylinders. A user study was conducted to demonstrate that our VR tool allows general users to effectively and creatively model a variety of man-made shapes, some of which have been 3D printed to validate their fabricability and usability.
