HOWIN TSUI

nodeGTFS (2014) is a small node.js script that periodically downloads full General Transit Feed Specification(GTFS) formatted data and allows basic queries using a RESTful API, in order to provide modularized data to a client.

N-body problem (2014) Combining my interests in both astronomy and programming, I wrote a simulator in ActionScript3 using verlet integration that models a solar system, complete with a moon.

DrawTogether (2013) is a collaborative real-time paint application. It uses websockets, with the server written in Java, and the client written using JavaScript. Users in the same room will be able to see each other draw in real time. Rooms are wiped when no users are left in the room. This project is a work in progress.

webVAB (2012) is a web application, written with PHP and JavaScript, making use of WebGL. It allows players to upload and share their spaceships from the game, Kerbal Space Program. This project has been put on hold, due to possible copyright issues with game textures, forcing me to render the ships as colored geometry rather than complete models.
