The goal of this assignment is to refine our JavaScript knowledge while exploring the multimedia capabilities of the browser. -[WebAudio / Canvas / Three Tutorial](https://github.com/cs4241-21a/cs4241-21a.github.io/blob/main/webaudio_canvas_three.md) -[SVG + D3 tutorial](https://github.com/cs4241-21a/cs4241-21a.github.io/blob/main/using_svg_and_d3.md) +## Your Project -Baseline Requirements ---- +On the front-end, -Your application is required to implement the following functionalities: +- Edit `views/index.html` to change the content of the webpage +- `public/client.js` is the javacript that runs when you load the webpage +- `public/style.css` is the styles for `views/index.html` +- Drag in `assets`, like images or music, to add them to your project -- A server created using Express.

[tweakpane](https://cocopon.github.io/tweakpane/) is highly recommended for this, but you can also use regular HTML `` tags (the `range` type is useful to create sliders). You might also explore interaction by tracking mouse movement via the `window.onmousemove` event handler in tandem with the `event.clientX` and `event.clientY` properties. Consider using the [Pointer Events API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events) to ensure that that both mouse and touch events will both be supported in your app. -- Your application should display basic documentation for the user interface when the application first loads. +On the back-end, -The interactive experience should possess a reasonable level of complexity.

Your interface controls the behavior / appearance of these agents. -- A simple 3D game... you really want this to be a simple as possible or it will be outside the scope of this assignment. -- An 3D audio visualization of a song of your choosing. User interaction should control aspects of the visualization. -### Canvas -- Implement a generative algorithm such as [Conway's Game of Life](https://bitstorm.org/gameoflife/) (or 1D cellular automata) and provide interactive controls. Note that the Game of Life has been created by 100s of people using ; we'll be checking to ensure that your implementation is not a copy of these. -- Design a 2D audio visualizer of a song of your choosing. User interaction should control visual aspects of the experience. -### Web Audio API -- Create a screen-based musical instrument using the Web Audio API. You can use projects such as [Interface.js](http://charlie-roberts.com/interface/) or [Nexus UI](https://nexus-js.github.io/ui/api/#Piano) to provide common musical interface elements, or use dat.GUI in combination with mouse/touch events (use the Pointer Events API). Your GUI should enable users to control aspects of sound synthesis. If you want to use higher-level instruments instead of the raw WebAudio API sounds, consider trying the instruments provided by [Tone.js]() or [Gibber](https://github.com/charlieroberts/gibber.audio.lib). -### D3.js -- Create visualizations using the datasets found at [Awesome JSON Datasets](https://github.com/jdorfman/Awesome-JSON-Datasets). Experiment with providing different visualizations of the same data set, and providing users interactive control over visualization parameters and/or data filtering. Alternatively, create a single visualization with using one of the more complicated techniques shown at [d3js.org](d3js.org) and provide meaningful points of interaction for users. +- your app starts at `server.js` +- add frameworks and packages in `package.json` +- safely store app secrets in `.env` (nobody can see this but you and people you invite) -Deliverables ---- +Click `Show` in the header to see your app live.
