Web3D city modeling competition

A competition for the best browser-based 3D rendering of a city

Submission Deadline April 15, 2015

PRIZE: The winner will receive financial support (500$) and free registration to attend the 20th International Web3D 2015 Conference on Web3D Technology in Heraklion, Crete Greece 18-21 June 2015.

Solution Criteria:

  1. Open Software solution to stream a large 3D city model including textured buildings, terrain, sensor, and model data.
  2. The Solution should be a browser based Web Service.
  3. The client side should be able to select individual features (a building) and display further information about the selected feature.
  4. The Web Service and the streaming protocol have to be documented and open.
  5. For the streaming, an existing data format such as X3DOM, XML3D, and KML can be used; other open solutions will also be accepted.
  6. Streaming should not be a “black box” and should enable interoperability.

Source data:
  1. All Competitors must use the same source data of Rotterdam City
  2. CityGML data files for Rotterdam
  3. Terrain data from ETOPO or local terrain model
  4. Any freely accessible data (water level, weather forecast, or other sensor/model data)
  5. Maps and other features can be added on top of the terrain. These can be integrated as OGC Services.

Criteria for judging will be based on:
  • Creativity in addressing a use case,
  • Loading performance,
  • Interactive performance,
  • Diversity of data rendered,
  • Interoperability and openness of the solution

How to submit your work to the Web3D City Modelling Competition
Please include a short description and the following with your submission:
Submitting Authors / Developers
Name, email, affiliation
Student (PhD, Master/Bachelor) at German University (yes/no)
Young German Startup Company (yes/no) *[1]

Please highlight the following (max. 500 words)

How did you implement the client?
  • WebGL, using a JavaScript lib such as x3dom.js,
  • XML3D.js, three.js, etc.,
  • just images due to server side rendering

Do you support a tiling scheme?
  • What is the size of the tiles?
  • Do you support a hierarchical tiling?

How do you transfer the data from the server to the client?

Please give a short description of the streaming protocol (if applicable)

Which browser (version) did you use to test the application?

Did you include some special data sources / special features you would like to highlight?

See you in Crete!

*[1] As we have a special prize of the best contribution of a startup / student from Germany donated by the German Special Interest Group on 3D City Models (AK 3D Stadtmodelle: http://www.3d-stadtmodelle.org), we also need to know if you fit into this category.


Share and explore methods of using, enhancing and creating new 3D Web and Multimedia technologies such WebGL and HTML5 (which is a hot topic in Computer Graphics), Flash/ Stage 3D, X3D, COLLADA, and the MPEG family. The conference highlights capabilities and trends in interactive 3D graphics across a wide range of applications and supports research from mobile devices up to high-end immersive environments.
