dc.description.abstractThe Blob Tree provides a hierarchical data structure for the definition of complex models built from implicit surfaces, CSG Boolean operations and space warping functions. The implicit model within the system is defined as a hierarchical composition of multiple objects. In this paper, we describe an application of the Blob Tree to create visually accurate models of two invertebrates, the sea anemone, Stomphia Coccinea, and the sea star, Dermasterias Imbricata. The sea star was created using a variety of parameters that could be modified to create different variations of the Dermasterias Imbricata species. We use the phyllotactic method to obtain an accurate and visually pleasing arrangement of the sea anemone's tentacles. Using a hierarchical construction of the model, we can refine the model locally and deform it globally while maintaining the integrity of surface details. Taking advantage of the hierarchical representation of the object, we can easily adjust the model by simply changing some parameters of the surface or by performing global deformations on the anemone or local refinements on the tentacles.eng
