Big Data Visualization Workshop

Nov 13

Posted by admin in Events, Information Visualisation | No Comments

Do you know the real value of your data?

– Visualise your data and learn the true meaning and value of your data for you, your organisation and your partners.
At the exclusive hands-on workshop on Big Data Visualisation we show you how your data can be transformed from a big list of symbols to visualisations that can be understood, interpreted and fed into decision processes. 4 keynote speakers will guide us through a day of hands-on work-stations covering:

  1. Creating value from data through business models;
  2. Mapping the interactions between data and use;
  3. Creating beautiful and useful mock-ups of big data.

Each hands-on workstation will be manned by experts in the area, guiding the participants thorough a number of steps to develop a (1) Business Model Canvas, (2) Story Board about User Interactions and (3) Visualisation Mock-Up, based on your data and ideas.

Interactive infographics in WebGL

Oct 12

Posted by admin in Information Visualisation, WebGL | 1 Comment

In a previous post we presented a bar diagram as a quick overview over data from Danish municipalities. We have now released a live demo that utilizes some of the newest html5 features, e.g. WebGL.

Click here to launch the demo. You need a recent chrome, firefox, safari (non iOS) or opera browser. Internet Explorer is not supported.

Use the keys "wasdqe" and the mouse to navigate and change between dataset in the right column.

Molecular Visualization using OpenGL / GLSL

Sep 12

Posted by admin in Events, GPGPU, Information Visualisation, Medical Applications, Realistic Rendering | No Comments

This video demonstrates our real-time molecular visualization application written using OpenGL and GLSL. The video features three distinct visualizations: Stick-and-ball, Connolly surface and density plot. The application renders the molecule using image-based lighting combined with depth-of-field. Ambient occlusion and fog is further used to enhance the perception of depth. The Connolly surface can be dynamically recreated when changing the orbital or probe radius. When recreating the Connolly surface the ambient occlusion is dynamically updated. The density plot, which features five separate density fields, is composited onto the rasterized geometry using raymarching.





The application is part of a presentation which will be given at Symposium on Scientific Visualization held on September 25th - 26th, 2012 at The Royal Danish Academy of Sciences and Letters in Copenhagen.

Denmark rendered as a jigsaw puzzle :-)

Recently the Danish Ministry of the Interior and Health published a lot of key figures about Danish municipalities on a new web page ( http://www.noegletal.dk ). We put a little effort into making a pipeline capable of  turning all those numbers into nice graphics. The figure seen above is an example of what our software can do. It is basically a bar diagram where each bar (or 'brick') is a municipality and the bar height and color encodes a quantity - here the population figure is shown.

Capital Globe

Dec 21

Posted by admin in Information Visualisation | 1 Comment

Capital Globe is a result of our initial exploration of the iphone API. It can be used as a tool to help you learn more about the countries of the world. The capital cities are shown as dots on a globe. By rotating the globe you can shift your focus between different cities and name of the country and capital is displayed along with the flag of the country. A map mode is also available letting you explore each country in more detail. Finally the application lets you browse the Wikipedia entry for each country. Capital Globe is now on the app store.

Klimatrends – free iphone app now on app-store

Dec 7

Posted by admin in Information Visualisation | No Comments

As part of the Digital Urban Living project we have developed our first iphone app, which is now available in app store:

http://www.digitalurbanliving.dk/projects/civic-communication/klimatrends-iphone-app-english.php

833857

The climate trend app is an innovative and different way to keep up with news, opinions, emotions and environmental sensors before, under and after COP15, the United Nations Climate Change Conference in Copenhagen (December 7-18, 2009).

The app is not simply a newsreader, a social network, a measuring apparatus or a game. It's a bit of all of that, and more.

* The ocean level indicates the climate situation right now. The worse the situation, the higher the water level. The level is not an exact measure but a reflection of many impressions.
* The ice floes that emerge from below are opinions, articles and readings from CO2 sensors in Copenhagen.
* Tap an ice floe to investigate it further.
* If you are a Twitter user, you can influence the situation, both in the application and through other Twitter applications (by adding #jpcop15 in a tweet).
* You can follow other people and see what they think and how they feel right now about the climate situation.

The primary language in the app is danish. We have implemented both an OpenGL ES1.1 version and a OpenGL ES2.0 version.
