Abstract
Modeling of realistic looking plants is still a complex problem
requiring specification of the plant structure, geometry and surface
characteristics. Modeling a collection of plants is more problematic
especially since each plant is slightly different. Altering the shape of
branches and stems is one of the most dramatic and natural methods of
creating differing instances of the same plant type. In this paper, we present
a sketch-based interface for modeling plant variations through specification
of branch and stem shape. Our system is based on interaction with the 3D
Tractus: a new physical interface we developed to support direct 3D sketching.
The 3D strokes from the 3D Tractus are used as input to a biologically-based
modeling method that mimics natural growth variation factors of real plants.
