arbitrary equal division function

divide an arbitrary curve into pieces along the curve without coordinate dependency

Description

Divide an arbitrary curve into pieces along the curve without coordinate dependency. Example script file generating the title screen shot shows below:

%spiral of Archimedes
a=1;
t=0:0.2:20; % theta
r=a*t; % r
x = r.*cos(t);
y = r.*sin(t);
z = t;
% polar(t,r,'-or');
subplot(1,2,1);
plot3(x,y,z,'-r');axis equal;
grid on;
[xx,yy,zz] = CurveSliceHomogenize3D(x,y,z,400);
hold on;
plot3(xx,yy,zz,'-*k');axis equal;
title('spiral of Archimedes');

• Required Products: MATLAB
• MATLAB release: MATLAB 7.5 (R2007b)

I confess that my implementation is not as good as the follow job. good for him/her :-]

if you have got the same problem of spacing a curve into equally several pieces you'd better refer to the link above directly and save your time.
