What a VR walkthrough needs
A virtual reality walkthrough is a real-time build. Real-time means the picture is drawn as the visitor moves, the way a video game works, instead of being rendered in advance. At the place where it is shown it needs a VR headset, the hardware to run it, a clear area of floor and a person to help visitors and guide them.
That makes VR a format for a place you control: a sales office, an experience centre, an exhibition stand or a design presentation. A buyer cannot open it at home from a link. For buyers at home, the same build can be streamed to a web browser, or you can give them a 360° tour.
