Polygonization of Implicit Surfaces
, 1988
"... This paper discusses a numerical technique that approximates an implicit surface with a polygonal representation. The implicit function is adaptively sampled as it is surrounded by a spatial partitioning. The partitioning is represented by an octree, which may either converge to the surface or track ..."

Modelling with Implicit Surfaces that Interpolate
 ACM Transactions on Graphics
, 2002
"... We introduce new techniques for modelling with interpolating implicit surfaces. This form of implicit surface was first used for problems of surface reconstruction [24] and shape transformation [30], but the emphasis of our work is on model creation. These implicit surfaces are described by specify ..."

Variational Implicit Surfaces
, 1999
"... We introduce a new method of creating smooth implicit surfaces of arbitrary manifold topology. These surfaces are described by specifying locations in 3D through which the surface should pass, and also identifying locations that are interior or exterior to the surface. A 3D implicit function is crea ..."

An Implicit Surface Polygonizer
 Graphics Gems IV
, 1994
"... Introduction Some shapes are more readily defined by implicit, rather than parametric, techniques. For example, consider a sphere centered at C with radius r. It can be described parametrically as {P}, where: (P x , P y , P z ) = (C x , C y , C z )+(r cosb cosa, r cosb sina, r sinb), a (0, 2p), b ..."

Using Particles to Sample and Control Implicit Surfaces
, 1994
"... We present a new particlebased approach to sampling and controlling implicit surfaces. A simple constraint locks a set of particles onto a surface while the particles and the surface move. We use the constraint to make surfaces follow particles, and to make particles follow surfaces. We implement c ..."

Isotopic implicit surface meshing
 STOC'04
, 2004
"... This paper addresses the problem of piecewise linear approximation of implicit surfaces. We first give a criterion ensuring that the zeroset of a smooth function and the one of a piecewise linear approximation of it are isotopic. Then, we deduce from this criterion an implicit surface meshing algor ..."

Guaranteed Ray Intersections with Implicit Surfaces
, 1989
"... In this paper, we present a robust and mathematically sound rayintersection algorithm for implicit surfaces. The algorithm is guaranteed to numerically find the nearest intersection of the surface with a ray, and is guaranteed not to miss fine features of the surface. It does not require fine tuni ..."

Trimming implicit surfaces

"... ABSTRACT Algorithms of trimming implicit surfaces yielding surface sheets and stripes are presented. These twodimensional manifolds with boundaries result from settheoretic operations on an implicit surface and a solid or another implicit surface. The algorithms generate adaptive polygonal approxi ..."

Implicit surfaces that interpolate
 Proceedings of the 7th International Conference on Shape Modeling and Applications

"... Implicit surfaces are often created by summing a collection of radial basis functions. Recently, researchers have begun to create implicit surfaces that exactly interpolate a given set of points by solving a simple linear system to assign weights to each basis function. Due to their ability to inter ..."
