Modelling spiral phyllotaxis

Abstract In this paper, established geometric models of phyllotaxis are used to generate realistic images of flowers and fruits with spiral patterns. Two approaches to the placement of organs are considered: spiral arrangement on a plane and spiral arrangement on the surface of a cylinder. Images of sunflowers, daisies and zinnias have been synthesized using the planar model, while the cylindrical model is illustrated by pine cones and a pineapple.
