Virtual Reality Tours have been around for many years, though it took a lot of time to put them together. At the time they needed special subsystem software to allow you to see the VR tour on your computer and it didn't play in all desktops and smart devices.
You can search the internet for 360 VR's and find some that won't play in your present browser, let alone your smart devices. They probably feel it takes too much effort to get working again.
I found one this week that prompted me to install version 9 of Java scripting. Of course, the newer technology VR as used here a Honu360VR is using the very latest in programming technology.
We also use the latest camera technology and techniques that help us to capture the images we need for the tours.
