Crate curve_sampling

This module provide a collection of routines to perform adaptive sampling of curves as well as manipulating those samplings.

As of now, the following is available:

• uniform sampling of the graph of functions ℝ → ℝ (see Sampling::uniform);
• adaptive sampling of the graph functions ℝ → ℝ (see Sampling::fun);
• adaptive sampling of the image functions ℝ → ℝ² (see Sampling::param).

Samplings can be saved as a list of coordinates x-y, one point per line with blank lines to indicate that the path is interrupted, with Sampling::write. They can also be saved in a format usable from the LaTeX package TikZ using Sampling::latex. This format allows to add arrows to the curves to indicate their orientation.

Structs

BoundingBox

A two dimensional rectangle [xmin, xmax] × [ymin, ymax].

Fun

Options for sampling graphs of functions ℝ → ℝ. See Sampling::fun.

LaTeX

LaTeX output, created by Sampling::latex.

Param

Options for sampling the image of functions ℝ → ℝ². See Sampling::param.

Sampling

A 2D sampling. This can be thought as a path, with possible “cuts” because of discontinuities or leaving the domain of the (parametric) function describing the path.

SamplingIter

Iterator on the curve points (and cuts).

SamplingIterMut

Mutable iterator on the curve points (and cuts).

Uniform

Options for uniform sampling graphs of function ℝ → ℝ. See Sampling::uniform.
