Modeling realistic looking plants is still a complex problem requiring specification of plant structure, geometry and surface characteristics. Modeling a collection of plants is more problematic especially since each plant ...

In this paper, we present a sketch-based technique for specifying transformations for general models by means of a single stroke, offering a more streamlined form of user interaction. The shape of the stroke is interpreted ...

Interactive volume segmentation is an essential and important step in medical image processing. Conventional interactive methods typically demand significant amounts of time and do not lend to a natural interaction scheme ...
