BUBBLEWORLD BUILDER - 3D Modeling using Two-touch and Sketch Interaction
Amit Joshi, Glen Robertson, Burkhard Claus Wuensche, Beryl Plimmer · 2010
Commercial 3D modeling applications tend to be difficult and time consuming to use due to complex interfaces and functionality. In this paper we present a simple and intuitive interface for modeling “blobby” 3D objects using touch input. Objects are defined by sketching and modifying contours of cross-sectional slices. Two-touch interactions are used to zoom, rotate and slice the object. The resulting application allows rapid creation of 3D models and looks promising for medical imaging applications. A drawback is that intuitiveness depends on a user’s mental abilities such as 3D vision and the ability to develop a mental model and compare it with visual data. 1
