Enum AnimSource 

pub enum AnimSource {
    Snapshots(Vec<ParamState>),
    Curves(HashMap<String, AnimCurve>),
}

A source of time-varying morph parameters for baking animated frame sequences. See the module docs for the accepted JSON shapes.

Variants

Snapshots(Vec<ParamState>)

One fully-resolved ParamState per output frame (frame count is fixed).

Curves(HashMap<String, AnimCurve>)

Continuous per-parameter animation curves, keyed by parameter name, sampled at an arbitrary time in seconds.

Implementations

impl AnimSource

pub fn fixed_frame_count(&self) -> Option<usize>

The frame count implied by this source, if it is fixed (dense form only).

pub fn suggested_frame_count(&self, fps: f32) -> usize

A reasonable default frame count for curve sources: enough frames at fps to cover the longest-running parameter curve, at least one frame.

pub fn params_at_frame(&self, i: usize, fps: f32, start_time: f32) -> ParamState

Resolve the ParamState to apply for output frame i.

For the dense (snapshot) form, i indexes directly into the array (clamped to the last entry so callers never index out of range). For the curve form, each named parameter curve is sampled at t = start_time + i / fps.

Trait Implementations

impl Clone for AnimSource

fn clone(&self) -> AnimSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnimSource

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

Formats the value using the given formatter.
