Crate hyperbolic_drawing 

Library for manipulating and displaying elements of 2D hyperbolic space (ℍ²).

All implementation is done in terms of the hyperboloid model, without requirements for normalization.

The component along the axis of the hyperboloid is named t (in reference to spacetime algebra). However, contrary to popular convention, we use γ₀² = −1 and γ₁² = γ₂² = 1. As such, elements on the hyperboloid are normalized to p² = −1.

Modules

svg

Elements for interfacing with the svg crate.

svg_common

Common elements for interfacing with either the svg or svg_fmt crates.

svg_fmt

Elements for interfacing with the svg crate.

Structs

Center

A center of some transformation in ℍ²: a point, ideal point, or line.

IdealPoint

An ideal point (‘point at infinity’) in hyperbolic space.

Line

A unitized line in hyperbolic geometry. Enables some additional calculations compared to WeightedLine.

Motor

Precomputed values for performing a motion on other objects.

Point

A unitized point in hyperbolic space. Enables some additional calculations compared to WeightedPoint.

WeightedLine

A line in hyperbolic geometry.

WeightedPoint

A point in 2D hyperbolic space.

Enums

CenterKind

The kind of a Center as determined by Center::classify.

Traits

Multivector

An element of the Clifford algebra 𝒢(2,1) under the homogenous coordinates interpretation.

Scalar

Common trait for operations available on float types.

Unitize

A common implementation for unitizing (scaling to weight ±1) a multivector.
