Struct SegmentTime 

pub struct SegmentTime {
    pub global_secs: f64,
    pub global_delta_secs: f64,
    pub start_secs: f64,
    pub duration_secs: f64,
    pub local_secs: f64,
    pub local_delta_secs: f64,
    pub alpha: f64,
    pub render_frame: u64,
    pub is_render_frame_boundary: bool,
}

A complete time context for one evaluation/step of an animation segment.

All time values are in seconds (_secs); alpha is normalized to [0, 1]. Deltas are only meaningful during Eval::step; during sampling they are zero.

Fields

global_secs: f64

Global scene time t at the current logic tick (seconds).

global_delta_secs: f64

Global logic step length, stable (= 1 / logic_fps).

start_secs: f64

Segment start s in its parent’s coordinates (seconds).

duration_secs: f64

Segment duration D (seconds).

local_secs: f64

Rate-warped local time u(t) = D · r((t−s)/D) (seconds).

local_delta_secs: f64

Local increment Δu for this step, varies with the rate function (seconds).

alpha: f64

Normalized progress alpha = local_secs / D.

render_frame: u64

Current render frame index (for frame-coupled segments).

is_render_frame_boundary: bool

Whether this logic step completes a render frame (for frame-coupled segments).
