The future of property viewing is here, thanks to software from a Melbourne-based company that allows potential buyers to take a virtual walk through a home so it feels like they are actually standing inside. Scann3d sets up a 3D camera on a tripod inside the home and rotates it around the room to film every detail and measure its exact dimensions. The camera's images are then pulled together so viewers can virtually walk from room to room as if they were physically inspecting the property, getting a more accurate impression of the property than traditional photos provide. "You have the control to actually walk around and look behind the bed and get a sense of space and the layout," Scann3d's Trent Clews-De Castella told AAP. "You are immersed in it. It gives a powerful sense of environment." Clews-De Castella says the 3D technology is cheaper to produce than traditional video used to advertise homes, and will eventually replace it and traditional photos. He has just demonstrated the Scann3d technology to a group of more than 100 Australian entrepreneurs taking part in a think tank in Antarctica.
