Struct AnimationClip 

pub struct AnimationClip {
    pub duration: f32,
    pub looping: bool,
    pub tracks: Vec<JointTrack>,
    pub morph_keys: Vec<(f32, Vec<f32>)>,
    pub root: Option<RootTrack>,
}

One animation clip: a fixed-length set of per-joint keyframe tracks.

Fields

duration: f32

Total clip length in seconds.

looping: bool

When true, sampling past duration wraps; otherwise it holds the end.

tracks: Vec<JointTrack>

One track per animated joint.

morph_keys: Vec<(f32, Vec<f32>)>

Morph-target weight keys in time order: (time, one weight per target). Empty for clips that animate no morph targets.

root: Option<RootTrack>

The character-displacement curve stripped from the root joint at build time, when the clip opted into root motion. The pose tracks above keep the root anchored; the runtime turns this curve’s frame delta into character movement instead.

Implementations

impl AnimationClip

pub fn sample_into(&self, t: f32, skeleton: &Skeleton, out: &mut Vec<Mat4>)

Sample the clip at time t against skeleton, writing one local matrix per joint into out (cleared first, so its capacity is reused). Joints with no track keep their bind transform.

pub fn sample_looped_into( &self, t: f32, looping: bool, skeleton: &Skeleton, out: &mut Vec<Mat4>, )

sample_into with the loop mode supplied by the caller instead of the clip’s own flag. Lets a graph state override looping without cloning the clip.

pub fn sample_morph_weights_into( &self, t: f32, looping: bool, out: &mut Vec<f32>, )

Sample the morph-weight track at time t into out (cleared first, so its capacity is reused), lerping between the surrounding keys with the same wrap/clamp semantics as pose sampling. out is left empty when the clip has no morph keys.

Trait Implementations

impl Clone for AnimationClip

fn clone(&self) -> AnimationClip

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnimationClip

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