Video Trace: 3D Models from Video

By 3D Modelling

VideoTrace is a system for interactively generating realistic 3D models of objects from video. The user interacts with VideoTrace by tracing the shape of the object to be modelled over one or more frames of the video.

By interpreting the sketch drawn by the user in light of 3D information obtained from computer vision techniques, a small number of simple 2D interactions can be used to generate a realistic 3D model.

In many ways the system is similar to the sadly demised CANOMA but with video, the movie below provides a good insight into how Video Trace works:

By way of simple comparison with CANOMA below is a movie we created some 8 years ago from a postcard – if we had the video capability it would of provided a similar output to Video Trace:



A version of CANOMA but from video is an intriguing step forward – if this can be semi-automated then low end rapid capture of city models could be round the corner.

You can find out more about Video Trace via their main page.

London Aerial Photography – 4cm Super Zoom

By mapping

192.com has published the highest resolution imagery of London we have seen. Coming in at a staggering 4cm resolution the imagery is of such quality to pin point individuals and with it come privacy concerns.

The Guardian’s Technology section has a full article covering these issues:

The map, from 192.com, publishes aerial photography at a resolution of 4cm for London and 12.5cm for the rest of the UK. In the right conditions, images at this resolution are enough to identify individuals – a step that existing online mapping ventures such as Google Earth and Microsoft’s Virtual Earth have so far been careful to avoid.

You can read the full article here.

* as an update – the site has great resolution but the interface and screen layout is poor – if it was in Google Maps or Live Local it would be great, as it is its a bit of a disappointment *

*you can view the maps full screen via a beta flash interface by clicking here – the extra screen space definitely helps. Thanks to eAI for the tip in our comments box, the long URL got truncated, thus our update*

Virtual Purdue: Future City Animation

By 3D City, Purdue


Istanbul is at such high risk for a devastating earthquake that engineers at Purdue University and the Republic of Turkey have come up with a bold new proposal: build a second city.

A second, satellite city would provide immediate refuge to inhabitants of the old city in the event of a catastrophic earthquake and soften such an event’s effects on the nation’s economy.

The animation of the future Turkish city was created in two months by using the TeraGrid, a National Science Foundation-funded research computing grid.

Purdue is one of 11 research institutions that comprise TeraGrid, which is the world’s largest open science computing grid. The movie is embedded below:

The animation was rendered using the TeraGrid Distributed Rendering Environment, or TeraDRE, developed by research scientists in Information Technology at Purdue.

See Purdue University News for more info.

It would be interesting to read peoples thoughts on the output, feel free to post your comments..
