Struct EmotionSpace 

pub struct EmotionSpace { /* private fields */ }

A collection of EmotionAnchors that defines an interpolatable emotion space.

Implementations

impl EmotionSpace

pub fn new() -> Self

Create an empty emotion space.

pub fn add_anchor(&mut self, anchor: EmotionAnchor)

Add an anchor to the space.

pub fn anchor_count(&self) -> usize

Return the number of anchors.

pub fn find_anchor(&self, name: &str) -> Option<&EmotionAnchor>

Find an anchor by name (case-sensitive).

pub fn default_space() -> Self

Build the default space with Ekman’s seven basic emotions mapped to PAD space.

Each emotion has a canonical set of facial morph target weights drawn from common MakeHuman-style expression unit names.

pub fn evaluate(&self, pad: &PadPoint) -> HashMap<String, f32>

Evaluate expression weights at pad using inverse-distance weighting (IDW).

Uses power = 2.0 (standard Shepard’s method).

pub fn evaluate_rbf(&self, pad: &PadPoint, sigma: f32) -> HashMap<String, f32>

Evaluate expression weights using Gaussian RBF interpolation.

sigma controls the width of influence: smaller = sharper, larger = broader.

pub fn nearest_anchor(&self, pad: &PadPoint) -> Option<&EmotionAnchor>

Find the nearest anchor to pad in PAD space.

pub fn valence_blend(&self, valence: f32) -> HashMap<String, f32>

Blend expression weights along the valence (pleasure) axis at valence ∈ [-1, 1].

Arousal and dominance are held at 0.

pub fn arousal_blend(&self, arousal: f32) -> HashMap<String, f32>

Blend expression weights along the arousal axis at arousal ∈ [-1, 1].

Pleasure and dominance are held at 0.

Trait Implementations

impl Default for EmotionSpace

fn default() -> Self

Returns the “default value” for a type.
