get_curvature() is function that computes the curvature of a
streamline object. The curvature \(\kappa(s)\) at each point
along the arc-length abscissa is computed using cubic smoothing
splines (3 degrees of freedom per component).
Arguments
- x
A streamline object.
Value
A non-negative numeric vector of length x@n_points giving the
curvature \(\kappa(s)\) at each sampled point along the streamline.
Higher values indicate sharper bending at that location.
Examples
sl <- streamline(points = cbind(X = runif(10), Y = runif(10), Z = runif(10)))
get_curvature(sl)
