- We propose novel methods to generate a sequence of shapes that represents the pattern of morphological development ortransformation of a B챕zier curve. The methods utilize the intrinsic geometric structures of a B챕zieer curve that are derived from rib andfan decomposition (RFD) [Lee and Park 2005]. Morphological development based on RFD shows a characteristic pattern of structural growth of a B챕zier curve, which is the direct consequence of development path defined using fans. Morphological transformation based RFD utilizes development patterns of given curves inspired by the theory of evolutionary developmental biology: although two mature curves are quite different in shapes, we can easily find similarities in their younger shapes, which makes it easier to set up featurre correspondences for blending. Further controls on base transformation and extrapolation ratio can determine the dominance of features and compensate the immaturity that may occur during the transformation. The developmeent and transformation patterns generated with the methods have smooth and unique geometric style that cannot be generated using conventional methods based on multi-linear blending.
