Enum ChartSide 

pub enum ChartSide {
    SPlus,
    SMinus,
    TPlus,
    TMinus,
}

Which side of a chart square a cube edge is: the chart’s other coordinate runs along the edge.

Variants

SPlus

s = +1

SMinus

s = -1

TPlus

t = +1

TMinus

t = -1

Implementations

impl ChartSide

pub const ALL: [ChartSide; 4]

pub fn edge(self, chart: usize) -> (usize, f64)

The cube edge this side of chart chart lies on, and the sign relating the chart’s free coordinate f to the edge parameter: q = sign · f.

This is the single place the two charts meeting along a cube edge agree about its identity and its direction, so a subdivision computed once in q reaches both of them unchanged.

pub fn coords(self, f: f64) -> (f64, f64)

(s, t) of the point at free coordinate f on this side.
