If you’ve been shopping for houses or apartments online in recent years, you may have run into 3D virtual walkthroughs — these are software models of interior spaces you can “walk” through by clicking on a computer screen, or by wearing VR glasses (still not widely available.) After initially clumsy and low-res beginnings, these have now become quite useful, allowing you to see finishes, traffic flow, and even appliance labels far more than is possible in the 30-40 photos now standard for high-end house listings. This makes it more practical for overseas and remote buyers to consider buying a house without ever having seen it in person.
The VR model is created using a specialized camera setup. The photographer places the camera tripod at eye level in representative spots throughout the space, and software stitches the resulting high-res 360-degree photos together into a virtual model of the interior.
