Visitors to Madrid this weekend have another attraction to consider.
Telefonica, the Spanish telecommunications company, has partnered with its subsidiary Movistar to present the Nadal Challenge. The experience, which will go on tour after it leaves Madrid on Tuesday, includes a virtual reality game in which users can play against Rafael Nadal.
The game uses a stereoscopic 360-degree video of Nadal set against a green screen and chroma key and accompanied by the 3D modeling of 300 photographs to create the virtual reality environment. The game presents real-time situations and objects to mimic the effect of playing on an actual tennis court.
