Augmented Reality in BIMx, the idea is that the entire hypermodel and plans can be displayed on the site, and perhaps be able to locate it with a QR code in both directions (BIMx Model and real building/terrain). There is a Brazilian application that already does that with the IFC models, but without the plans, it is called Augin. And it also integrates BCF files.
Sorry, I wouldn't hold your breath for any type of BIMx update around augmented/virtual reality. BIMx is so far behind other applications in this respect. The phone app still has an option for google cardboard! The world has moved far past this point when it comes to VR/AR. As mentioned by other posts there are a number of option out there through providers who understand the value of VR/AR and are willing to put the $ in to develop it properly. They will come at a cost but everything that's worth using has a cost. BIMx could actually be a great asset for AC but it is under developed due to the fact that GS think it is amazing already. At some point they will look out the window of their office and realize they have missed an entire decade of development.....but by then it will be too late.☹️
