Abstract: Methods and systems for determining the shape of an object based on shadows cast by the object are described. An example method may include receiving a plurality of images of an object casting a shadow. Each image may include a shadow cast by the object as the object is illuminated by a light source that moves over a plurality of positions. The method may further include determining, by a computing device, respectively for each image of the plurality of images a two-dimensional (2D) silhouette of the object and a respective position of the light source relative to the object. According to the method, a three-dimensional (3D) object data model of the object may be generated by the computing device based on the 2D silhouette of the object and the respective position of the light source relative to the object for each image of the plurality of images.

Abstract: An example method may involve a computing device receiving low-resolution images of an object and high-resolution images of the object. The method may also involve causing a 3D image viewer to display a first high-resolution image of the object. The method may further involve receiving an input associated with adjusting a view of the object in the 3D image viewer. The method may still further involve, based on the input, causing the 3D image viewer to sequentially display at least a portion of the low-resolution images so as to adjust the view of the object in the 3D image viewer. The method may yet still further involve, in response to a completion of the sequential display, causing the 3D image viewer to display a second high-resolution image of the object that corresponds to a respective low-resolution image of the object displayed at the completion of the sequential display.

Abstract: System and methods for rendering three-dimensional (3D) object data models based on a comparison of images. A 3D object data model of an object can be characterized by parameters defining rendering features of the 3D object data model. A comparison can be made of a first rendering of the 3D object data model to one or more reference images related to the object and, based on the comparison, the parameters of the 3D object data model can be modified. Following the modification, the 3D object data model can be rendered to generate a second rendering. Based on the second rendered 3D object data model, statistical information can be obtained and based on the statistical information, the parameters of the 3D object data model can be modified again to further adjust the appearance of the second rendering of the 3D object data model.
