|Title:||HIERARCHICAL MODELING OF BLOB TREE WITH PRIMITIVE BASED LOCAL REFINEMENT|
|Abstract:||This paper presents a novel method for implicit modeling of Blob Tree. Instead of modeling the implicit surface with shape transformations, refinement of the polygonization mesh or implicit particles, we introduce a method which builds a dynamic hierarchy of implicit surfaces and directly manipulates the surfaces and primitives. Based on the implicit primitives, the model is gradually refined by introducing appropriate new primitives at the specified surface areas. Refinement constraints such as local area and level of primitive hierarchy are designed to be applied on the implicit surfaces so as to achieve finer control over the local surface. The method can be used not only in modeling complex implicit objects, but also in animating the implicit surfaces and simulating the deformations of various objects.|
