Polygonization of implicit surfaces

TL;DR: An application independent algorithm that uses local operations on geometry and topology to reduce the number of triangles in a triangle mesh and results from two different geometric modeling applications illustrate the strengths of the algorithm.

TL;DR: A technique for rendering images of volumes containing mixtures of materials is presented, which allows both the interior of a material and the boundary between materials to be colored.

TL;DR: The Numerical Continuation Methods for Nonlinear Systems of Equations (NCME) as discussed by the authors is an excellent introduction to numerical continuuation methods for solving nonlinear systems of equations.

TL;DR: This paper describes a new method for contouring a signed grid whose edges are tagged by Hermite data (i.e; exact intersection points and normals) and develops an octree-based method for simplifying contours produced by this method.

TL;DR: This study investigates the effects of underground structures on wave propagation and surface ground acceleration, employing a nonlinear cyclic model to analyze the impact of input motion, embedment, and dimensions on spectral ratio, peak ground acceleration, and relative displacement under near-fault and far-fault earthquakes.

TL;DR: L'accentuation est mise sur la representation de donnees dans les applications de traitement d'images, d'infographie, les systemes d'informations geographiques and the robotique.

TL;DR: Efficient (linear time) algorithms have been developed for the Boolean operations, geometric operations,translation, scaling and rotation, N-dimensional interference detection, and display from any point in space with hidden surfaces removed.

TL;DR: A new algorithm applicable to other functional forms, in particular to the summation of several gaussian density distributions is presented, created to model electron density maps of molecular structures but can be used for other artistically interesting shapes.
