Free-form deformation of solid geometric models
- IN PROC. SIGGRAPH 86
, 1986
"... A technique is presented for deforming solid geometric models in a free-form manner. The technique can be used with any solid modeling system, such as CSG or B-rep. It can deform surface primitives of any type or degree: planes, quadrics, parametric surface patches, or implicitly defined surfaces, f ..."

Rendering of Surfaces from Volume Data
- IEEE COMPUTER GRAPHICS AND APPLICATIONS
, 1988
"... The application of volume rendering techniques to the display of surfaces from sampled scalar functions of three spatial dimensions is explored. Fitting of geometric primitives to the sampled data is not required. Images are formed by directly shading each sample and projecting it onto the picture ..."

Abstract Synthetic carving using implicit surface primitives
"... Several techniques of computer-aided synthetic carving are presented. We describe both procedural methods for relief carvings and patterned lattices, as well as interactive carving. Different techniques of depth data generation for relief carving are described: polygon-tofunction conversion, pattern ..."

Fast Extraction of Surface Primitives from Range Images
, 1996
"... An efficient algorithm for extracting planar and curved surface patches that express distinctive parts of the objects contained in a given range image is presented. The proposed technique does not directly segment the range image but a triangular approximation of it obtained through a fast adaptive ..."

Particle Systems - A Technique for Modeling a Class of Fuzzy Objects
- ACM Transactions on Graphics
, 1983
"... This paper introduces particle systems--a method for modeling fuzzy objects such as fire, clouds, and water. Particle systems model an object as a cloud of primitive particles that define its volume. Over a period of time, particles are generated into the system, move and change form within the syst ..."

A finite-volume, incompressible Navier–Stokes model for studies of the ocean on parallel computers.
- J. Geophys. Res.,
, 1997
"... Abstract. The numerical implementation of an ocean model based on the incompressible Navier Stokes equations which is designed for studies of the ocean circulation on horizontal scales less than the depth of the ocean right up to global scale is described. A "pressure correction" method i ..."

field is separated into surface, hydrostatic, and nonhydrostatic components. First, as in hydrostatic models, a two-dimensional problem is inverted for the surface pressure which is then made use of in the three-dimensional inversion for the nonhydrostatic pressure. Preconditioned conjugate
RENDERING FUR WITH THREE DIMENSIONAL TEXTURES
, 1989
"... We present a method for rendering scenes with fine detail via an object called a texel, a rendering primitive inspired by volume den-sities mixed with anisotropic lighting models. This technique solves a long outstanding problem in image synthesis: the rendering of furry surfaces. ..."

Non-Linear Approximation of Reflectance Functions
, 1997
"... We introduce a new class of primitive functions with non-linear parameters for representing light reflectance functions. The functions are reciprocal, energy-conserving and expressive. They can capture important phenomena such as off-specular reflection, increasing reflectance and retro-reflection. ..."

Hierarchical mesh segmentation based on fitting primitives
- THE VISUAL COMPUTER
, 2006
"... In this paper we describe a hierarchical face clustering algorithm for triangle meshes based on fitting primitives belonging to an arbitrary set. The method proposed is completely automatic, and generates a binary tree of clusters, each of which fitted by one of the primitives employed. Initially, e ..."
