Abstract
A 3D model of an object is rendered using centered images of the object. An algorithm executed locally or in a distributed manner calculates camera positions for the images and determines a virtual camera path based on the camera positions. The application adjusts the images to fit the plane of the virtual camera path and fills in the gaps between the images using transition renderings. To improve user experience, the application also calculates resting positions for navigation stop points using a spring system. Upon constructing the 3D model, the application can transmit the 3D model to a variety of user devices including the network connected device having a camera module that captured the images.
