New York Taxi’s: Origins vs. Destination Viz

By Posts One Comment

Carrying on form our previous post – Origins vs. Destinations visualises  data drawn from a random sample of New York City Yellow Cab GPS data collected in 2010:


Programmed by Juan Francisco Saldarriaga, Spatial Information Design Lab, Graduate School of Architecture, Planning and Preservation at Columbia University the data is drawn from the work of David A. King, Graduate School of Architecture, Planning and Preservation at Columbia University and Jonathan R. Peters, College of Staten Island.

For more details on this research take a look at http://davidaking.blogspot.com/2012/01/visualizing-nyc-taxi-activity.html

CityEngine: ESRI and Lumion a first look.

By arcGIS, Architectual Visualisation, CityEngine, data viz, ESRI, Lumion, Procedural Cities No Comments

Yesterday a license for CityEngine landed on our desk from the nice people at ESRI and to be honest we were a little too excited for our own good, after all its only software. However, CityEngine and its integration with ESRI ArcGIS, while maintaining full export capabilities to load into 3DMax/Lumion/Unity etc, is a game changer.

It moves GIS visualisation a step forward while at the same time bringing procedural city modelling into the mainstream game engine world. Over the coming weeks we will be putting the software through its paces and exporting into Max/Lumion and Unity as part of introducing CityEngines onto our MRes in Advanced Spatial Analysis and Visualisation. The clip below details out first output direct from CityEngine into Lumion, adding in a general landscape, sample trees and transport objects:

Linking in our previous post on ArcGIS Twitter Visualisation in Lumion it seems that the worlds of GIS and architectural visualisation/game engines are finally starting to become accessible.

Demo – Live 3D Kinect Streaming: The Future of Webcams

By Posts No Comments

George MacKerron here in CASA has been looking at using a Kinect or three in our forthcoming ANALOGIES (Analogues of Cities) conference + exhibition.

Inspired in part by Ruairi Glynn‘s amazing work here at UCL, along with Martin at CASA who has been happily experimenting with the OpenKinect bindings for Processing, George has recently got to grips with the excellent Three.js, which makes WebGL — aka 3D graphics in modern browsers. As a fan of making things accessible over the web he has begun to investigate prospects for working with Kinect data in HTML5 and the results are intriguing – a live 3D, movable webcam…

View the live stream here or click on the screenshot to connect (note it needs Chrome at the moment), you can also pan and zoom around with the mouse. Hopefully George will be at his desk for the full effect.

For those without Chrome, the movie below details the concept:



We view this as a glimpse of the future of webcams, the next step is to up the resolution (bandwidth heavy)  and add image data. The implications for video conferencing or indeed that industry that academically we probably cant mention are notable…

Take a look at the blog post from George for full technical details.
