Assignment 4 - Creative Coding: Interactive Multimedia Experiences

Due: October 11th, by 11:59 PM.

For this assignment we will focus on client-side development using popular audio/graphics/visualization technologies; the server requirements are minimal. The goal of this assignment is to refine our JavaScript knowledge while exploring the multimedia capabilities of the browser.

Baseline Requirements

Your application is required to implement the following functionalities:

• A client-side interactive experience using at least one of the following web technologies frameworks.
  • Three.js: A library for 3D graphics / VR experiences
  • D3.js: A library that is primarily used for interactive data visualizations
  • Canvas: A 2D raster drawing API included in all modern browsers
  • SVG: A 2D vector drawing framework that enables shapes to be defined via XML.
  • Web Audio API: An API for audio synthesis, analysis, processing, and file playback.
• A user interface for interaction with your project, which must expose at least six parameters for user control. tweakpane is highly recommended for this. 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 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.

The interactive experience should possess a reasonable level of complexity. Some examples:

Three.js

• A generative algorithm creates simple agents that move through a virtual world. Your interface controls the behavior / appearance of these agents.
• A simple 3D game
• 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 (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 or Nexus UI 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.

D3.js

• Create visualizations using the datasets found at 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 and provide meaningful points of interaction for users.

Deliverables

Do the following to complete this assignment:

1. Implement your project with the above requirements.
2. Test your project to make sure that when someone goes to your main page on Glitch/Heroku/etc., it displays correctly.
3. Ensure that your project has the proper naming scheme a4-firstname-lastname so we can find it.
4. Fork this repository and modify the README to the specifications below. NOTE: If you don't use Glitch for hosting (where we can see the files) then you must include all project files that you author in your repo for this assignment.
5. Create and submit a Pull Request to the original repo. Name the pull request using the following template: a4-firstname-lastname.

Sample Readme (delete the above when you're ready to submit, and modify the below so with your links and descriptions)

Your Web Application Title

your hosting link e.g. http://a4-charlieroberts.glitch.me

Include a very brief summary of your project here. Images are encouraged when needed, along with concise, high-level text. Be sure to include:

• the goal of the application
• challenges you faced in realizing the application
• the instructions you present in the website should be clear enough to use the application, but if you feel any need to provide additional instructions please do so here.
