ComputationA B-spline is defined by the degree and quantity of knots, and it is observed to provide a higher level of flexibility in curve and surface layout. The extended cubic B-spline (ExCBS) functions with new approximation for second derivative and finite ...

Point constraints for B-spline surfaces based on energy model and least square method
, 2007 This paper presents an algorithm of the point constraint for B-spline surfaces. Based on static energy model, the shape of the surface can be sculpted in an intuitive manner by changing the force distribution vector and control point constraint, thus ...

An arbitrary mesh network scheme using rational splines
, 1991 A C1 surface scheme is described which interpolates points defined on an arbitrary mesh network. The scheme involves the blending of strip ‘functions’ developed from a rational spline method.

B-Spline Wavelet-Based Multiresolution Analysis of Surface Texture in End-Milling of Aluminum
, 2011 Modern manufacturing requires close monitoring by correlating finer frequency regimes of the surface texture to process parameters. This paper presents a study of B-spline wavelet-based multiresolution analysis (MRA) for surface texture characterization ...

Curve and Surface Representations for Bezier B-spline Systems
, 1979 The Bezier approach to the computer-aided design of surfaces, using interactive design of curves to construct surface sections, can be implemented using spline curves just as well as the original polynomial curves, and with some advantages. In the paper,

Medical Object 3D Modelling Using B-spline Surface
3D visualization of a medical object is an important and actual task in medical engineering. At the same time, the input data for this task often is described in 2D layer form (for example, medical images acquired with Magnetic Resonance Imaging ...

An Iterative Deflectometry Method of Reconstruction of Separate Specular Surfaces
SensorsPhase measuring deflectometry (PMD) plays a more and more significant role in the measurement of specular surfaces. However, most of the deflectometric methods are only suitable for continuous specular surfaces, but not for the discontinuous surfaces. In

Smooth parametric surfaces and n-sided patches
, 1989 The theory of 'geometric continuity' within the subject of CAGD is reviewed. In particular, we are concerned with how parametric surface patches for CAGD can be pieced together to form a smooth Ck surface.
