Sending & Receiving SMS on Linux

A little while ago I worked on a mixed media theatre production called If There Was A Colour Darker Than Black I’d Wear It. As part of this production I needed to build a system that could send and receive SMS messages from audience members. Today we’re looking at the technical aspects of how to do that using SMS Server Tools. Continue reading Sending & Receiving SMS on Linux

How OpenNI Nearly Spoiled The Show

Half RealSo, for the last few months I’ve taken a break from the PhD to do some work for a theatre show for The Border Project, Half Real.

There’s a lot of technology in the show. In particular, most of the set is projected, and we are using a Microsoft Kinect to track the actors on stage, and modifying the projections based on their location.

I’m working on Linux, and using OpenNI for interfacing with the Kinect. Things almost worked perfectly. In this post I will document the trials and tribulations of getting the Kinect to work for Half Real.

Kinect on Ubuntu with OpenNI

UPDATED March 1 2014 for the latest versions of everything!

I’ve spent all this morning trying to talk to the Microsoft Kinect using OpenNI. As it turns out, the process is not exceptionally difficult, it’s just there doesn’t seem to be any up to date documentation on getting it all working. So, this post should fill the void. I describe how to get access to the Kinect working using Ubuntu 12.04 LTS, OpenNI 1.5.4, and NITE 1.5.2. Continue reading Kinect on Ubuntu with OpenNI

Behaviours Demo – Android Programming

Hey Everyone

So this week I became a member sponsor on The first thing I had a look at was their XNA Behaviour Programming videos, which are the first in their set on AI programming. However, not being particularly interested in XNA, I implemented the algorithms presented in the videos for Android.

Here’s a video of the demo running on my Nexus One:

Since I was on Android and only using the Android and OpenGL ES libraries, I had to write a lot of low level code to replace the XNA functionality that 3DBuzz’s videos rely on. I also had to implement an on-screen joystick. I might write up a couple of posts on the more interesting parts of the code (what is not in the videos) soon.


OpenSceneGraph, Dual Screens & TwinView

So some of my work at uni involves programming using OpenSceneGraph. Now, anybody who has used OSG before will know that as powerful as it may be, it is seriously lacking in the documentation department. So, this article describes how to do dual screen graphics on Linux using OpenSceneGraph. First we’ll look at the X Screens approach, which is easier but probably not the best solution. Then we’ll look at a method that works with a single X screen. Continue reading OpenSceneGraph, Dual Screens & TwinView
