The Web3D Consortium is pleased to announce a competition for the best
browser-based 3D rendering of a city. We seek software solutions to stream
a large 3D city model including textured buildings, terrain, sensor, and
model data. As a minimum requirement, the implementation has to use some
kind of a Web Service and be browser-based. On client side it has to be
possible to select individual features (a building) and display further
information about the selected feature. The Web Service and the streaming
protocol have to be documented and open. For the streaming, an existing
data format such as X3DOM, XML3D, KML might be used, but other solutions
are possible as well. However, the streaming should not be a “black box”
but should enable interoperability.

All competitors will be provided the same source data which are:

   - CityGML data files
   <http://www.web3d.org/competition/city-modeling-2015/rotterdam-information>
   for Rotterdam (a presentation about these data
   
<http://www.3d-stadtmodelle.org/3d-stadtmodelle_2012/vortraege/15_Smit_Rotterdam3D_und_Open_Data.pdf>
   )
   - Terrain data from ETOPO
   <http://www.ngdc.noaa.gov/dem/squareCellGrid/map?theme=DDP> or local
   terain model
   
<http://studenten.tudelft.nl/en/students/faculty-specific/architecture/facilities/tu-delfts-map-room/manuals/ahn/>
   - Any freely accessible data (water level, weather forecast, or other
   sensor/model data)
   - Maps and other features can be added on top of the terrain. These can
   be integrated as OGC Services online
   <https://www.pdok.nl/en/products/pdok-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

*The winner will receive financial support to attend the 20th International
Conference on 3D Web Technology in Heraklian, Crete, Greece. *

Submission date is 2015 April 12.
