Matterport are quite expensive, it can be as $500 / year to store few of your 3d walkthroughs. And Im not trying to replace it or something, I just knew that many online floor plan aggregators, construction builders and etc looking for a way to turn their floor plans into 3D or walkthrough videos.
Admittedly I have no idea what an "online floor plan aggregator" is, but I don't see why any of Matterport's commercial property management customers would want to put in the far greater amount of work this requires of them rather than just throwing some money at Matterport to come out and scan it?
We're building our first home with a local construction company down here in Australia. I remembered browsing house designs using a virtual 3d plan that enabled me to walk around the house. Your idea looked very similar. I found one example online and turns out they're using Matterport.
