The goal of this assignment is to refine our JavaScript knowledge while exploring the multimedia capabilities of the browser. -Baseline Requirements ---- +# basic requirement +Used canvas to add a 2D music visualizer by drawing a circle in the middle, then added the bars around it that has animation and will change according to frequency. +Used Sakura CSS template (the same one from last proj). +User Interface include (6): pause, play, bar color, radius, background color, bar length. +User Interface is displayed as a pop-out alarm when the website is opened. It will pop out again if you press the help button. -Your application is required to implement the following functionalities: - -- A server created using Express. This server can be as simple as needed. -- A client-side interactive experience using at least one of the following web technologies frameworks. - - [Three.js](https://threejs.org/): A library for 3D graphics / VR experiences - - [D3.js](https://d3js.org): A library that is primarily used for interactive data visualizations - - [Canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D raster drawing API included in all modern browsers - - [SVG](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D vector drawing framework that enables shapes to be defined via XML. - - [Web Audio API](https://developer.mozilla.org/en-US/docs/Web/API/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. [dat.gui](https://workshop.chromeexperiments.com/examples/gui/#1--Basic-Usage) 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](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events) to ensure that that 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. This documentation should be dismissable, however, users should be able to redisplay it via either a help buton (this could, for example, be inside a dat.gui interface) or via a keyboard shortcut (commonly the question mark). -- Your HTML and CSS should validate. There are options/plugins for most IDEs to check validation. - -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](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. -### 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. - -Deliverables ---- - -Do the following to complete this assignment: - -1. Implement your project with the above requirements. -3. Test your project to make sure that when someone goes to your main page on Glitch/Heroku/etc., it displays correctly. -4. Ensure that your project has the proper naming scheme `a4-firstname-lastname` so we can find it. -5. 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*. -6. 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. +# challenge +At first I tried to inplement dat.gui, but then I found that it was much easier if I just parsed the value(change theme? radius length?) and then get then using an id.
