Struct ProportionLayer 

pub struct ProportionLayer { /* private fields */ }

Proportion entries resolved against one skeleton, ready to apply to a local-pose buffer every frame without further lookups.

Implementations

impl ProportionLayer

pub fn resolve( skeleton: &Skeleton, proportions: &[JointProportion], ) -> ProportionLayer

Resolve proportions against skeleton by joint name. Entries naming an unknown joint are skipped (the caller reports them); entries that change nothing are dropped.

pub fn is_empty(&self) -> bool

Whether no joint is changed.

pub fn apply(&self, locals: &mut [[[f32; 4]; 4]])

Apply the layer to locals (one local matrix per joint, as sampled from a clip or copied from the bind pose). A joint’s scale multiplies its local basis; its children’s local translations gain the length offset. Entries past the end of locals are ignored.

pub fn root_scale(&self, skeleton: &Skeleton) -> f32

Uniform scale of the skeleton’s first root joint, or 1 when no entry changes it.

pub fn height_ratio(&self, skeleton: &Skeleton) -> f32

Ratio of the proportioned skeleton’s height to the bind height, both measured as the highest joint position (model Y) in the rest pose. 1 when the bind skeleton has no height.
