Creates a polynomial deformed cylinder.

Description

Creates a polynomial deformed cylinder.

Usage

polynomial_cylinder(length_body, radius_body, n_segments, polynomial)

Arguments

length_body	Length (m).
radius_body	Maximum/uniform radius (m).
n_segments	Number of segments to discretize object shape. Defaults to 1e2 segments.
polynomial	Polynomial coefficient vector.

Value

Creates the position vector for a polynomial deformed cylinder.

Examples

## Not run: 
# We can use the polynomial coefficients defined in Smith et al. (2013) to
# define the position vector of a sub-Arctic krill.
poly_vec <- c(0.83, 0.36, -2.10, -1.20, 0.63, 0.82, 0.64)
# Create the position vector
# This outputs a list containing "rpos" and "radius"
pos <- polynomial_cylinder(length_body = 15e-3, radius_body = 2e-3, polynomial = poly_vec)
str(pos)
