Sketch Interface for 3D Modeling of Flowers

Abstract

We present a user interface that easily models flowers from freehand sketches. The user creates the models by sketching on a transparent canvas displayed in 3D space. To model the stalk of a flower, the user draws two strokes, which indicate a shadow and the appearance of the stalk. To model a leaf or petal, the user first draws the strokes representing the outline of the leaf, and the interface creates a plane-like leaf object. The user then draws modifying strokes representing the 3D form of the leaf, and it transforms the leaf object accordingly.
