Struct FacsMapper 

pub struct FacsMapper { /* private fields */ }

Maps FACS Action Units to morph-target weights.

Each AU can influence one or more named morph targets with a configurable weight at full (1.0) intensity. The Self::evaluate method scales each morph contribution by the AU intensity and accumulates the results.

Implementations

impl FacsMapper

pub fn new() -> Self

Create an empty mapper.

pub fn add_mapping( &mut self, au: ActionUnit, morph: impl Into<String>, weight: f32, )

Register a morph target for the given AU.

weight is the morph-target weight applied when the AU has intensity 1.0. Multiple calls for the same AU accumulate additional mappings.

pub fn mappings_for(&self, au: &ActionUnit) -> &[(String, f32)]

Return the list of (morph_name, weight) pairs registered for au.

pub fn evaluate(&self, state: &FacsState) -> HashMap<String, f32>

Convert a FacsState into a flat map of morph-target weights.

For each active AU, each associated morph target receives a contribution of intensity × weight_at_full. When multiple AUs influence the same morph target, contributions are summed and clamped to [0.0, 1.0].

Trait Implementations

impl Default for FacsMapper

fn default() -> Self

Returns the “default value” for a type.
