This paper surveys methods for simplifying and approximating polygonal surfaces. A
polygonal surface is a piecewiselinear surface in 3-D defined by a set of polygons; typically …

We describe an improved, anatomically based approach to modeling and animating
animals. Underlying muscles, bones, and generalized tissue are modeled as triangle …

These tutorial notes provide an introduction, review, and discussion of the state-of-the-art on
simplification methods, Level Of Detail, and multiresolution models for surface meshes, and …

This thesis presents a generic and principled solution for optimising the visual complexity of
any arbitrary computer-generated virtual environment (VE). This is performed with the …

We describe a method for reconstructing an unknown surface from a set of data points. The
basic approach is to extract the surface as a polygon mesh from an α‐shape. Even though …

We describe a method for reconstructing an unknown surface X of arbitrary topology,
possibly with boundaries, from a set of scattered points. Our method generates a parametric …

In order to construct a 3D model from a collection of 2D images of an object, an energy
function is defined between the object's images and corresponding images of an articulated …

A system and method for modeling smooth free-form shapes using B-splines over irregular
meshes, in a simple and efficient manner, to generate a display of aesthetically pleasing …

We present a model-based method for the multi-level shape, pose estimation and
abstraction of an object's surface from range data. The surface shape is estimated based on …

Three-dimensional (3D) visualization techniques are becoming an important tool for medical
applications. Computer-generated 3D reconstructions of the human skull are used to build …
