Interactive Face-Replacements for Modeling Detailed Shapes

In this paper, we present a method that allows novice users to interactively create partially self-similar manifold surfaces without relying on shape grammars or fractal methods. Moreover, the surfaces created using our method are connected. The modelers that are based on traditional fractal methods or shape grammars usually create disconnected surfaces and restrict the creative freedom of users. In most cases, the shapes are defined by hard-coded schemes that provide only a few parameters that can be adjusted by the users. We present a new approach for modeling such shapes. With this approach, novice users can interactively create a variety of unusual and interesting partially selfsimilar manifold surfaces.
