Surface manipulation using a paper sculpture metaphor

The creation of 3D computer models is essential for many applications in science, engineering and arts and is frequently performed by untrained users. However, creating an intuitive mapping between 2D input and 3D models is a non-trivial task and is reflected in the difficulty novices have in using current 3D modelling software. Using metaphors of paper sculpture and pen sketching, our gesture based modelling tool simplifies this interaction mapping. More intuitive object manipulation means that an otherwise complex model can be rapidly created by an inexperienced, non-artistic user. To demonstrate this, we have chosen to model orchid flowers as they offer considerable challenges to the artist due to their complexity of shape and detail, especially the petal surfaces which vary a great deal in curvature.
