Two-dimensional drawings or renderings never quite capture the three-dimensional - spatial - nature of buildings. Traditionally, designers and builders have created - and sometimes still do - physical models to help simulate the feeling, features or physical aspects of an actual environment or building. With Virtual Reality (VR) all this information can be modelled and tested within an immersive environment where finishes and spaces can be edited and viewed in real time. It's faster, more flexible, and, we find, the better way. It also means designers and clients alike can, for instance, experience a fully-simulated visitor's journey in a hotel from entering the front entrance, to checking in and making their way to their guestroom. The same approach can be applied to any type of building, enabling the client, end user and design team to envisage the finished space and environment. There is also the added benefit in using VR in the design and collaboration process, of allowing clash detection and pinch points to be reviewed from a truly realistic perspective.
