ν-SPLINE CURVES FOR BOUNDARY GEOMETRY MODELING IN TWO-DIMENSIONAL POTENTIAL BOUNDARY VALUE PROBLEMS WITH SINGULAR CORNER POINTS

TASK Quarterly, 2002
The paper presents a new modeling method of boundary geometry in boundary valueproblems by ν-spline curves. To define a smooth boundary geometry both B´ezier and B-spline curves are applied. At the segment join points B´ezier curves ensure continuity C1,

A new “walking spline” method for smoothing polylines on the maps using B-spline functions based on an iteratively optimised set of vertices

Polish Cartographical Review
This research paper proposes a new method for smoothing polylines on a map, using B-splines iteratively moving away from the vertices. Splines are a popular tool used to smooth data.

B - Spline [PDF]

, 2017
U ovom radu upoznat ćemo se s još jednim pojmom iz Numeričke analize, B-spline. Definirat ćemo B-spline i neka njegova osnovna svojstva, te pokazati kako se računa. Bavit ćemo se pronalaskom stabilnog i brzog algoritma za procjenu B-spline funkcije F. Za

A tension approach to controlling the shape of cubic spline surfaces on FVS triangulations

, 2009
We propose a parametric tensioned version of the FVS macro-element to control the shape of the composite surface and remove artificial oscillations, bumps and other undesired behaviour.
