FSOSS 2011- Free Software and Open Source Symposium

Introduction

FSOSS is an event which offers presentations and workshops about the latest trends in open source used in schools, labs and industries. The goal of the symposium is to explore how open source, open standards, and open content are changing technology, the web, the media and arts, education, and business.

Being a volunteer at FSOSS I got the chance to watch four presentations. But the two main presentations I was interested in were “Building a Commercial Game Using Processing.js for Cross-platform Delivery” and “XB PointStream: Rendering Point Clouds with WebGL”. I will be writing my research paper on these two topics as I know the presenters Daniel Hodgin and Andor Salga, and it will better to analyze my report on their thoughts about open source. The other two presentations I watched were “Unity and GNOME 3” and “Popcorn.js & Popcorn-Maker”.

Building a Commercial Game Using Processing.js for Cross-platform Delivery

This presentation was about using the Processing.js libraries and how this project created a cross platform, plugin free HTML 5 game that requires no install time. Processing.js is a programmer and artist friendly language that enables the creation of graphically complex interactive applications which can be instantly ported to the web and any mobile devices.

Daniel Hodgin, the project manager and David Perit, the game designer of the team gave the background of the project. Both the developers talked about Processing and Processing.js and the development of the game and why these languages were used for the game. Both projects are Open Source and free to use and contribute to. Processing was originally developed at the MIT Media Lab by Ben Fry and Casey Reas. Processing.js is a port of the Processing language to JavaScript using the HTML canvas. Processing works on Windows and Mac, where as Processing.js works on Firefox, Chrome, Internet Explorer, Opera, Safari and mobile browsers that support the HTML5 canvas element. Processing.js does not require a plugin to be installed. This allows it to run in environments where plugins cannot be installed like mobile, business and public. As it is open source it has the ability to change things to work the way you want. There is full control and access to the development community to contribute and there is no licensing costs.

Daniel also talked about moving away from Flash as it will not work on Apple devices and the company Spongelab wants to reach the mobile iOS audience and its instantly portable. Then Daniel talked about developing the game. When Spongelab delivered a game design document outlining features of the game and how the game would progress and play, they started creating the storyboards of what screens would look like and how they would tie together. Then they programmed the screen structure and navigation and once the basic screens were put together they began programming game play mechanics and features. They wrote code to mimic the JAVA interaction with audio for the HTML5 Audio element. He told that when the game came together they began testing for bugs and performance issues. From this, they optimized load times and animation speeds. Once optimizations were made they did basic play testing to further improve the game play mechanics and the beta release of the game went out in early October.

XB PointStream: Rendering Point Clouds with WebGL

The second presentation was to introduce WebGL which allows hardware-accelerated graphics on the web and the XB PoinStream’s capabilities. Also the Seneca’s Center for Development of Open Technology has partnered with Arius3D to develop XB PointStream, an open source JavaScript framework for streaming and rendering point clouds (3D images) on a web page. Andor Salga, the presenter also showed us interesting assortment of demos.
