Struct Affine 

pub struct Affine {
    pub a: f32,
    pub b: f32,
    pub c: f32,
    pub d: f32,
    pub e: f32,
    pub f: f32,
}

One map’s raw affine coefficients: x' = a·x + b·y + e, y' = c·x + d·y + f.

The output form: what recompose produces and what the GPU is handed. It is also the form the curated tables are authored in, because published IFS coefficients are quoted this way and a reviewer can check them against a source. Nothing morphs or levers here — that all happens in IfsMap.

Fields

a: f32

Linear part, row 0 column 0.

b: f32

Linear part, row 0 column 1.

c: f32

Linear part, row 1 column 0.

d: f32

Linear part, row 1 column 1.

e: f32

Translation in x — never enters contractivity (ADR-0075).

f: f32

Translation in y — never enters contractivity (ADR-0075).

Trait Implementations

impl Clone for Affine

fn clone(&self) -> Affine

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Affine

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Affine

fn eq(&self, other: &Affine) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
