Abstract

It is important when making 3D virtual cities for virtual reality (VR) that they perform well as a “break in presence” (BIP) might occur when the FPS becomes too low. The key contributions of this research paper are a performance analysis that checks whether two separate virtual cities are “VR ready” on a recommended specification system to qualify for the Oculus Store (i.e., applications must meet a consistent 90 frames per second (FPS)) and several guidelines that are important when rendering large virtual cities for VR. Both virtual cities (Endless City Driver versions) without pedestrians and parked vehicles (but with foliage in the case of the next generation) are VR ready. Reducing the city tile size by half resulted in a much better performance in general.

For the ECD TOV this was not easily possible as the tiles were handmade, and the tiles do not fit together anymore if cropped.

The tiles should be large enough so that the end of the world is not easily visible.

For example, in the video game Grand Theft Auto V the cities were made by human artists which leads to high realism but also means a lot of time and effort in comparison to PCG content. “Los Angeles was extensively researched for the game. The team organised field research trips with tour guides and architectural historians, and captured around 250,000 photographs and many hours of video footage.” (Wikipedia Contributors, 2020).
