Porting BIM Models to Virtual Reality Using Google Cardboard

Abstract

Virtual Reality for BIM (Building Information Modelling) is an exciting development in the virtual design and construction (VDC) process. However, the lack of reasonably priced solutions along with lack of computing power on cellular devices has restricted its success and most people continue to use desktop solutions.

This paper dwelves into porting BIM models into virtual reality using the Google Cardboard: a low cost solution. The new perspective obtained when you view a BIM model in virtual reality will allow users to view scaled models as if they are actually in a real life structure. This, along with the relevant data attached to every 3D structure would provide users with a virtual walk-around of a BIM model. The advantage of the Google Cardboard is not only its affordability, but also its portability. For just 15 USD, anyone can insert their phone into a Google Cardboard and view a BIM model. The possibility of selectively loading sections of the model in a contextual manner from models published into a cloud service can also help circumvent the limitations of memory and computing power available on a mobile device.
