Struct BlendShapeSet 

pub struct BlendShapeSet {
    pub shapes: Vec<BlendShape>,
    pub weights: Vec<f64>,
}

A blend shape set with named targets and weights.

Fields

shapes: Vec<BlendShape>

The blend shapes.

weights: Vec<f64>

Current weights for each shape.

Implementations

impl BlendShapeSet

pub fn new() -> Self

Create a new empty blend shape set.

pub fn add_shape(&mut self, shape: BlendShape) -> usize

Add a blend shape and return its index.

pub fn set_weight(&mut self, idx: usize, weight: f64)

Set the weight for a blend shape.

pub fn evaluate(&self) -> HashMap<usize, [f64; 3]>

Evaluate the blend shapes and return the accumulated deltas per vertex.

The result maps vertex_index to accumulated delta.

pub fn interpolate_weights(a: &[f64], b: &[f64], t: f64) -> Vec<f64>

Interpolate weights between two sets of weights.

Trait Implementations

impl Clone for BlendShapeSet

fn clone(&self) -> BlendShapeSet

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

Performs copy-assignment from source.

impl Debug for BlendShapeSet

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

Formats the value using the given formatter.

impl Default for BlendShapeSet

fn default() -> Self
