Implicit surface transformation methods [40-42] represent source and target shapes by implicit functions.
For an implicit surface building mission, energy minimization can be solved using RBF (radial basis function), a well-established mathematical tool for solving scattered data interpolation problems [23], which accounts for its popularity in surface recovery applications.
The aim of implicit surface reconstruction is to obtain an implicit function from unconstructed scattered data using interpolation or approximation.
Among particular topics are an example-driven symbol recognition approach based on key features in engineering drawings, spherical projective displacement mesh, a variational harmonic method for parameterizing the computational domain in two-dimensional isogeometric analysis, an efficient adaptive vortex particle method for real-time smoke simulation, the behavior-based simulation of real-time crown evacuation, and implicit surface reconstruction based on adaptive clustering.
[13] proposed an algorithm for detecting ridges and valley lines that combines multi-level implicit surface fitting with finite-difference approximations.
The implicit surfaces of Schoen gyroid is defined by a function.
Twenty-three full papers and four short papers from a June 2007 conference are presented here, focusing on shape matching and retrieval, modeling with implicit surfaces, and various issues of shape analysis, representation, and processing.
The parametric and implicit surfaces are very often used in the sphere of computer graphics.
Twenty full papers and ten short papers from the June 2006 conference present recent research on shape matching and retrieval, modeling with implicit surfaces, and various issues of shape analysis, representation, and processing.
Papers from a December 2005 conference describe recent work in the fields of computer-aided design and computer graphics, in the areas of curves, surfaces, subdivision of surfaces, implicit surfaces and point-based surfaces, shape analysis, CAD systems, and reverse engineering and industrial applications.
