Tether Timeline

This is a Rust application that allows the creation and playback of timelines through a web UI.
You can create an arbitrary number of timelines, name them, set their duration, and specify whether or not they should loop.

A timeline can contain one or more tracks, which can currently be of the curve, event or color type.
Curve tracks define a single cubic bezier curve, and emit a single value on update.
Event tracks contain one or more triggers at distinct times, each containing an optional piece of data (currently limited to strings). Events are emitted

To trigger timeline playback, the agent listens to start and stop messages on topics that can be defined via configuration.

Agent

The main agent application is written in Rust. To build it, run the following from the app/ directory:

cargo build

and/or run it with

cargo run

The full timeline functionality is headless, i.e. it does not require the web UI in order to run.

Command line arguments

Provide any of the following arguments to configure the agent application:

• --tether.agent_id Optional Tether agent id
• --tether.host Optional Tether broker hostname or IP address. Defaults to 127.0.0.1.
• --tether.user Optional Tether user
• --tether.password Optional Tether password
• --http.port Network port to expose the server on. Defaults to 8888.
• --fps Frame rate to use for output. Defaults to 60.
• Set verbosity level with -v: warn, -vv: info, -vvv: debug, , -vvvv or more: trace

Web UI

The web UI is built to and served up by the Rust application. To build it, run the following from the ui/ directory:

npm run build

This compiles the assets and places them in app/public/. When running the agent application, the UI will be accesible via a web browser, on port 8888 unless otherwise specified in the launch arguments.
