  abstract = {Creating 3D plant models is often a hard and laborious task. To
              make it easier and more natural, we propose a sketch-based
              interface for modeling single-compound plant structures with
              phyllotactic arrangements. Our approach is based on the
              traditional illustration technique of concept sketching. The user
              sketches the key construction lines for the main plant body and
              lateral organs. Our system then automatically constructs the 3D
              plant arrangement in phyllotactic patterns rendered as pen-and-ink
              line drawings. The user is then able to edit the model by
              oversketching the construction lines, adjusting density of lateral
              organs, and specifying different phyllotactic patterns. We
              demonstrate the capabilities of our system for a variety of plant
              models.},
