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.
