Struct RootTrack 

pub struct RootTrack {
    pub keys: Vec<RootKey>,
}

The displacement curve of one clip, in the mesh’s model space. Keys are in ascending time order (the build bakes them from the root joint’s keyframe track, so they inherit its ordering).

Fields

keys: Vec<RootKey>

Curve keys, in ascending time order.

Implementations

impl RootTrack

pub fn sample(&self, t: f32) -> [f32; 3]

The curve’s translation at clip-local time t, clamped to the key range; between keys the translation lerps.

pub fn delta(&self, t0: f32, t1: f32, duration: f32, looping: bool) -> [f32; 3]

The displacement covered between two unwrapped clip times (t0 <= t1, in the same seconds the clip clock runs on). A looping clip adds one full per-cycle displacement for every wrap crossed, so a multi-loop frame (or a long hitch) loses no ground; a non-looping clip clamps both ends.
