An upcoming app, named Walkabout Worlds, is hoping to drastically simplify the process of creating a 3D model of existing spaces. Designed as both a tool for turning 360 photographs into 3D models and for creating photographic 3D walkthroughs for VR viewing, the app has turned heads for its demonstration that a 360 photograph can be converted into a rough, simple 3D model in as little as a minute by selecting key points in the image such as the corners of the room, as shown in the video below.
Basic 3D model building has been added to the walkabouts mobile app. You can now create simple photorealistic models straight from your mobile device and 360 camera. This is a screen capture of creating the model for a single room from start to finish (including taking the 360 image, marking corners of the room and generating the 3D model).
