Deformation of 3D shapes usually requires the use of a deformation tool. The freeform deformation technique requires the use of a lattice of control point for deforming an object. This may require a synchronized movement of the lattice control points in order to obtain the desired effects. The axial deformation technique allows an object to be deformed by manipulating an axial curve. However, u...

Along with the science research field is more and more wide, solve large-scale over determined system of linear equations has become an important problem , and the parallel processing technology also become the trend of the research. Firstly, this paper introduces the basic principle of the curve fitting least squares serial algorithm, based on the least square principle we found an parallel le...

A systematic approach is presented for fitting empirical expressions to da ta depending on two variables. The problem can also be described as the simultaneous fitting of a family of curves depending on a parameter . The proposed method reduces a surface fitting problem to t h a t of fitting a few functions of one variable each. First , t he surface is expressed in terms of these one-variable f...
