Official web site of 2018 Winter Olympics, held in South Korea, uses Blend4Web engine to showcase sport facilities and 3D maps.
The site features dozens of large-scale buildings and hundreds of smaller objects, all carefully recreated in full 3D along with interiors. The developers used a unique method of creating 3D content: photographic images are combined with 3D models. This approach allows creating almost photo-real scenes that work fine even on low-performance devices.
Every presentation is provided with both textual and graphical tips that help visitors to understand the functions of Olympic objects and infrastructure. The visitors are given an option to examine realistic-looking maps of the locations, which certainly is more helpful that contemplating schematic maps.
Presentations of indoor sport facilities also include options to examine inner structure of the buildings. Virtual tours help to explore the nuances of interior design and to find your place in the spectator stands that are divided into sectors. You can even select a sector and get an idea of the views that you can enjoy from this point.
Here are 3D presentations of the main sport facilities of the PyeongChang Winter Olympics:
