Struct PaintFrame 

pub struct PaintFrame {
    pub time: f64,
    pub scenario_time: f64,
    pub frame_index: u32,
    pub fps: u32,
    pub video_width: u32,
    pub video_height: u32,
    pub scene_duration: f64,
    pub camera: Option<PlaneCamera>,
}

Frame-level paint context (timing + viewport).

Fields

time: f64

scenario_time: f64

Seconds since the start of the scenario (of the view, for a world view), as opposed to time, which restarts at every scene.

Only the audio-reactive painters want this: an audio analysis is indexed on the scenario’s own timeline, so reading it with time gave a scene starting at t=73 s the analysis at 73 s into that scene. Everything else — animation progress, reveals, transitions — is correctly scene-local and must stay on time.

frame_index: u32

fps: u32

video_width: u32

video_height: u32

scene_duration: f64

Total duration of the scene in seconds — used by the dispatcher to compute animation progress (time / scene_duration).

camera: Option<PlaneCamera>

Resolved scene camera for per-plane parallax (issue #90). Some only when the scene declares a camera AND at least one top-level child has an explicit style.depth — the paint pass then applies the camera per plane (each direct child of the root, scaled by its depth) and the caller must NOT apply the global camera transform.
