bezier_polynomial: Bezier Polynomial Interpolator

Description

Constructs a Bezier polynomial interpolator given control points.

Usage

bezier_polynomial(control_points)

Value

An object of class bezier_polynomial with methods:

• interpolate(xi): Evaluate the interpolator at point xi.

• prime(xi): Evaluate the derivative of the interpolator at point xi.

• edit_control_point(new_control_point, index): Insert a new control point at the specified index.

Arguments

control_points

List of control points, where each element is a numeric vector of length 3.

Examples

control_points <- list(c(0, 0, 0), c(1, 2, 0), c(2, 0, 0), c(3, 3, 0))
interpolator <- bezier_polynomial(control_points)
xi <- 1.5
interpolator$interpolate(xi)
interpolator$prime(xi)
new_control_point <- c(1.5, 1, 0)
interpolator$edit_control_point(new_control_point, 2)
