The proposed 3D-volume-drawing interface can easily create various organic, artistic models. To provide intuitiveness, it adopts the metaphor of the potter's wheel. With one hand, users control a wooden wheel whose rotation is synchronized with that of the virtual space. A 3D depth camera captures the mid-air poses of the users' other hand, which the system translates into a virtual brush for interacting with a model. Through this configuration, the interface enables simultaneous view control and drawing. Also, because the brush's shape imitates the hand pose, the shape can vary. This makes our system flexible and maximizes expressiveness. With it, designers and artists can easily transfer their expertise to the virtual-modeling interface.
