Syntax

[V]=bezierCurve(p,n);

Description

This function uses the control points p to create a Bézier curve. The output V consists of n points on the curve.

Examples

Plot settings

fontSize=20;
lineWidth1=2;
lineWidth2=4;
markerSize1=50;
markerSize2=40;

Example 1:

p=[0 0 0; 1 1 1; 2 -1 1; 3 0 0]; %Control points
n=25; %Number of desired points

Using bezierCurve to get the curve coordinates for n points

V=bezierCurve(p,n);

cFigure; hold on;
hp1=plotV(p,'k.-','lineWidth',lineWidth1,'MarkerSize',markerSize1);
hp2=plotV(V,'r.-','lineWidth',lineWidth2,'MarkerSize',markerSize2);
legend([hp1,hp2],{'Control points','Curve'});
axisGeom(gca,fontSize); box on; grid on;
gdrawnow;

Example 2:

c=(4/3)*tan(pi/8);
p=[0 1; c 1; 1 c; 1 0;]; %Control points
n=25; %Number of desired points

Using bezierCurve to get the curve coordinates for n points

V=bezierCurve(p,n);

cFigure; hold on;
hp1=plotV(p,'k.-','lineWidth',lineWidth1,'MarkerSize',markerSize1);
hp2=plotV(V,'r.-','lineWidth',lineWidth2,'MarkerSize',markerSize2);
legend([hp1,hp2],{'Control points','Curve'});
view(2); axis tight; axis equal; box on; grid on;
set(gca,'FontSize',fontSize);
gdrawnow;
