Bezier surface

(graphics)
A surface defined by mathematical formulae, used in computer graphics. A surface P(u, v), where u and v vary orthogonally from 0 to 1 from one edge of the surface to the other, is defined by a set of (n+1)*(m+1) "control points" (X(i, j), Y(i, j), Z(i, j)) for i = 0 to n, j = 0 to m.

P(u, v) = Sum i=0..n Sum j=0..m [

B(i, n, u) = C(n, i) * u^i * (1-u)^(n-i)

C(n, i) = n!/i!/(n-i)!

Bezier surfaces are an extension of the idea of Bezier curves, and share many of their properties.

As an essential part of this quantitative analysis, formulated Bezier surfaces were used as resulting surfaces, which indicate the goodness of the tactical solutions and performance of an attack.
Extensive research has also been conducted to find means to describe the shape information of Bezier surfaces [8] for interpreting different modeled phenomena.
Because the surfaces are produced from measured data into the form of Bezier surfaces, it is possible to add mathematical comparison and pattern recognition in the CMEP method.

An example of the Bezier surface, which is calculated based on the measured data in the SCA research [5], for successful attacks is presented in Figure 5.
When evaluating the reliability aspects of the surface modeling, two main points were checked: How the selected Bezier surface calculation differed from other possible modeling techniques in relation to pattern recognition and what the difference is in grading.
FreeDimension is based on patented N-sided surfacing (NSS) technology, which frees users from quadrilateral surfacing technologies like NURBS and Bezier surfaces.

Bernard said Dassault had held off on implementing NURBS in Catia because Bezier surfaces have better continuity for complex curves.
In this paper we introduce a class of surface patch representations, called S-patches, that unify and generalize triangular and tensor product Bezier surfaces by allowing patches to be defined over any convex polygonal domain; hence, S-patches may have any number of boundary curves.
The 3-D capability will allow the analysis to handle the contact of deformable bodies idealized as curved shells and brick elements, and of rigid bodies modeled as flat patches, ruled surfaces, surfaces of revolution, or Bezier surfaces.
