Abstract: System and method for rotational video-like display of images of a gemstone in a viewer having a pan feature. In response to a pan command specifying a direction of rotation for a displayed gemstone, a computing system receives multiple datasets of images of the gemstone. Each dataset contains multiple images of the gemstone, with each image captured from a different angular perspective as compared to other images in the dataset. The different perspective can be captured, for example, around an axis of rotation that depicts the item at a particular angle of view. Once multiple images are received in a dataset, the images are progressively displayed in a viewer by transitioning between individual images in a certain order based on the received pan command. The pan command can specify both a direction and a magnitude of rotation, such as by clicking and dragging or swiping on a touchscreen.

Abstract: A system and method for progressively displaying images of an item to create a rotational video-like display. The displayed images are contained within multiple datasets that are received by a computing device. Each received dataset contains multiple images of the same item, with each image captured of the item from a different perspective as compared to the other images in the dataset. The different perspective can be captured, for example, around an axis of rotation that reflects the item at a particular angle of view. Once multiple images are received in a dataset, the images are progressively displayed to a user in a viewer by transitioning between individual images in a certain order so as to create the video-like display. The transitioning between individual images, including the speed of transition and selection of the next image to be displayed, can be controlled by the user.
