We have built a solution for this, however only offering as a web service at the moment.
Essentially you can view an entire city in your browser with 15-30cm accuracy in realtime (as example).
You simply upload your model, watch it convert and within minutes you can view, examine and share your result.
Obviously a big model will take time to upload but on the plus you share the model instantly rather than send non-interactive fly throughs.
Pricing is being finalised but its mostly geared for enterprise customers right now.
Currently in beta and will be making some big announcements soon (partnerships with leading VR manufacters too).
You can message me and I can provide details.
