Module linestring::nalgebra_3d

This module is optional. To use if you must include the feature impl-nalgebra in your Cargo.toml file.

By default all features are enabled (this is a work-around to enable the automatic rust doc). If you want to only enable the impl-nalgebra feature you must first disable the default features with default-features=false.

Cargo.toml example: linestring = {version="<current version>",default-features=false,features=["impl-nalgebra"]}

Structs

Aabb3	A simple 3d AABB If min_max is none the data has not been assigned yet.
Line3	A 3d line
LineString3	A 3d line string, aka polyline. If the ‘connected’ field is set the ‘as_lines()’ method will connect start point with the end-point. Todo: The builder structure of this struct needs to be revisited
LineStringSet3	A set of linestrings + an aabb Intended to contain related 3d shapes. E.g. outlines of letters with holes

Enums

Plane	Axis aligned planes, used to describe how imported ‘flat’ data is arranged in space
Shape3d	Placeholder for different 3d shapes

Functions

distance_to_line_squared	The distance between the line a->b to the point p is the same as distance = |(a-p)×(a-b)|/|a-b| https://en.wikipedia.org/wiki/Distance_from_a_point_to_a_line#Another_vector_formulation Make sure to not call this function with a-b==0 This function returns the distance²
distance_to_point_squared	The distance² between the two points
point_ulps_eq
save_to_obj_file	Rudimentary save line strings to .obj file function It is extremely inefficient, but it works. It saves with 6 decimals because that’s what Blender uses.
