Hello,
I am trying to interpolate a space curve in 3d using splines. This link (https://in.mathworks.com/help/curvefit/splines-in-the-plane.html) shows that the spline is parametrised by a single parameter t, and hence I can evaluate the spline curve at distinct points using fnval(curve, t). However, how do I know the limits (min and max) of this parameter t?
For example, here I plot an incomplete curve (in blue) using an arbitrary max of 100.5 (the min is 0, I presume). The entire curve is plotted in dashed red (see attached file):
t = linspace(0,100.5,501);
plot3(cv(1,:),cv(2,:),cv(3,:),'b','LineWidth',5);
