Level Set Methods And Dynamic Implicit Surfaces
This book is an introduction to level set methods and dynamic implicit surfaces. These are powerful techniques for analyzing and computing moving fronts in a variety of different settings. While the book gives many examples of the usefulness of the methods for a diverse set of applications, it also gives complete numerical analysis and recipes, which will enable users to quickly apply the techniques to real problems. The book begins with the description of implicit surfaces and their basic properties, and then devises the level set geometry and calculus toolbox, including the construction of signed distance functions. Part II adds dynamics to this static calculus.

Level Set Methods and Dynamic Implicit Surfaces
Level-set methods LSM are a conceptual framework for using level sets as a tool for numerical analysis of surfaces and shapes. The advantage of the level-set model is that one can perform numerical computations involving curves and surfaces on a fixed Cartesian grid without having to parameterize these objects this is called the Eulerian approach. All these make the level-set method a great tool for modeling time-varying objects, like inflation of an airbag , or a drop of oil floating in water. The figure on the right illustrates several important ideas about the level-set method. In the upper-left corner we see a shape; that is, a bounded region with a well-behaved boundary. In the top row we see the shape changing its topology by splitting in two. It would be quite hard to describe this transformation numerically by parameterizing the boundary of the shape and following its evolution.

Dynamic implicit surfaces prove useful in such fields as: Computational Geometry and Mesh Generation. Fluid and Combustion Simulation. Graphics and Animation. Image Processing and Computer Vision. The benefits of an implicit representation of surfaces include hassle free merging and separation of surfaces, easy computation of geometric properties like normals and curvature, and the fact that both curves in two dimensions and surfaces in three dimensions can be treated with the same theory and computational algorithms.

Description: Level set methods are a popular and powerful class of numerical algorithms for dynamic implicit surfaces and solution of Hamilton-Jacobi PDEs. While the advanced level set schemes combine both efficiency and accuracy, their implementation complexity makes it difficult for the community to reproduce new results and make quantitative comparisons between methods. This paper describes the Toolbox of Level Set Methods, a collection of Matlab routines implementing the basic level set algorithms on fixed Cartesian grids for rectangular domains in arbitrary dimension.

Сзади, перпендикулярно туннелю, начинался коридор, едва освещаемый красными лампочками, вмонтированными в пол. - Пойдемте, - позвал Бринкерхофф, помогая Сьюзан вылезти. Она шла следом за ним точно в тумане. Коридор, выложенный кафельными плитками, довольно круто спускался вниз, и Сьюзан держалась за перила, стараясь не отставать. Воздух в помещении становился все прохладнее. Чем глубже под землю уходил коридор, тем уже он становился.
Купол здания, похожий на спутник, находился в ста девяти ярдах от основного здания АНБ, и попасть туда можно было только через главный вход.
Ну хватит. Телефон заливался еще секунд пятнадцать и наконец замолк. Джабба облегченно вздохнул. Через шестьдесят секунд у него над головой затрещал интерком.
