Description

The purpose of this research is to develop a new procedure of modeling free-form mesh by modeling the network structure of “Phallus Indusiatus”. This network structure can be regarded as the freeform mesh made mainly of hexagons. In previous methods, mesh modeling has typically taken the procedure of, first, fixing the final surface form and then, splitting it into small hexagons of the same size. However, the mushroom shows various sizes and non homogeneous density of hexagons. In this paper, the authors take new approach: first, hypothesize the primary form for the mushroom; then, organize homogeneous Voronoi mesh over the primary form by deforming it according to internal dryness distribution; and finally gain the variety of the mushroom forms and, at the same time, non-homogeneous density of the hexagonal mesh.
