+# Vello Pacing
+
+A frame pacing library for wgpu, optimised for 2d graphics use cases.
+
+In particular, special care is taken to handle animation use cases correctly.
+
+## Backends
+
+This library currently only targets Android, but has working fallbacks for other platforms.

+///
+/// In the rendering once case, we just render as soon as possible.
+/// It *could* be possible to coalesce these updates.
+/// There are two phases to the multiple renders case:
+/// 1) Up-to-date control loop
+/// 2) Outdated control loop.
+///
+/// The outdated control loop case is due to the Presentation Time API having ~5 frames of latency.
+/// (see <https://themaister.net/blog/2018/11/09/experimenting-with-vk_google_display_timing-taking-control-over-the-swap-chain/>,
+/// the "Android 8.0, presentation timing latency" heading).
+///
+/// At the start of rendering, we are in the outdated control loop case, because of the above mentioned latency. That involves:
+/// 1) We render the first frame immediately. This uses a best-effort estimated present time.
+///    This does *not* have an requestedPresentationTime.
+/// 2) We then set about rendering the second frame, which uses an estimated present time *one* interval
+///    of display refresh rate after the first presentation. We start the rendering work for this frame
+///    (tunable) ~20% sooner than one refresh rate interval after the start of rendering work for the first frame.
+///    - If work has already finished on the first frame, then
+///    - A potential option here is to cancel this render (GPU side) if the previous frame took (significantly) longer
+///      than one refresh interval. It is future work to reason about this.
+///      We foresee this as potentially advantageous because the CPU side work would be a relatively small part of
+///      a frame, and so it would probably lead to "better" animation smoothness.
+/// 3) Once the first frame finishes rendering, we present the second frame. We use "render end time" - "render start time" (`T_R`) to
+///    estimate how many refresh durations (`N`) this render took, with a (tunable) ~25% "grace reduction" in the value.
+///    This grace amount is to account for a likely ramping up of GPU power states, so future frames will probably be faster.
+///    We also use `T_R` to estimate how many refresh durations the second frame will take to render (`N_2`), for scheduling the
+///    present of the second frame. This does not use the grace reduction, but does have a grace subtraction of ~45% of the refresh cycle to
+///    count as one frame. This grace period is to account for the fact that we don't know when in the refresh cycle we started rendering,
+///    so there's a chance that even if both frames took longer than one refresh duration to render, we can "fake" smoothness.
+///    Additionally, this slightly helps account for the GPU power state ramp-up.
+/// 4) We present the second frame with a time which is "render end time" + previous "present clock - latching clock" + `N_2`  * refresh durations.
+/// 5) We start rendering on the third frame, either `N_2 + N` or `2*N` (TBD) refresh durations after the first frame rendering started.
+///    This will have an estimated present time of the same `N_2 + N` or `2*N` refresh durations from the estimated present time.
+///
+/// Using a statistical model for the variable time from starting rendering from event `1` to `2`.

+/// A slightly tweaked version of the thinking, now that we have an understanding of `AChoreographer`.
+///
+/// Observations:
+/// 1) A frame drop can happen because CPU or GPU work overruns.
+/// 2) GPU work starts ~a fixed time after the end of the [`wgpu::Queue::submit`] call.
+/// 3) We can predict a frame drop due to CPU time problems due to this case.
+/// 4) Just dropping a frame is better than stuttering when we do so.
+///
+/// We need to think about three cases:
+///
+/// 1) The CPU-side work to prepare a scene is longer than one vsync. We ignore this case due to parallel command construction.
+/// 2) The GPU-side work to prepare a frame is longer than one vsync.
+/// 3) The total GPU+CPU side work is longer than one vsync (but individually each is shorter)
+/// 4) Neither is the case.
+///
+/// For the first draft of this feature, we focus only on the third of these.
+/// I.e. both the CPU and GPU side work of a frame are relatively cheap.
+/// N.B. we do `Scene` preparation on the main thread, but it is included in
+/// this CPU-side work.
+///
+/// The rendering loop goes as follows:
+///
+/// 1) We submit frame A.
+/// 2) We start the CPU side work for frame B at the estimated start time.
+/// 3) We race wait until the *deadline* for frame A with the CPU side work for frame B.
+/// 4) If the deadline happened first (normal case, GPU work less than 1 frame), we compare
+///    the timestamp of the end of the blit pass with the deadline.
+///
+/// For the moment, we ignore the possibility of a frame failing.
+/// That doesn't actually change any behaviour here, because we render with `MailBox`.
