Perception, Drawing and Interactive Modelling

Sketch interfaces have often been touted as “natural” approaches to interactive design. While this metaphor is indeed a promising medium of visual communication, there are a number of inherent limitations in human motor control, drawing skill, perception, and the ambiguities of inference, that make the leap from 2D input to 3D shape a challenging task. In this talk, I will present recent research, open challenges in the perception of shape from sketch input, and highlights of various systems such as true2formwww.ilovesketch.comwww.crossshade.comwww.meshmixer.com and www.flatfab.com, that facilitate the leap from 2D input to 3D models despite these limitations.
