3D Volume Drawing on a Potter´s Wheel

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.
