Abstract: A server for generating custom jewelry can be configured to access a first product photo based on a first user selection at a remote computer system of a first available selection for a first customization option. The server can send display instructions over a network to display the first product photo. The server can then generate an updated product photo by layering a second cached product photo (selected based upon a second user selection of a second available selection for a second customization option) with the first cached product photo according to a predetermined layering protocol. The updated product photo can display a second visual element of the second product photo overlaid on a first visual element of the first product photo. The server can send display instructions to cause the remote computer system to display the updated product photo in place of the first cached product photo.

Abstract: A computer system for just-in-time rendering using distributed cache servers can receive at least one edited photo comprising at least one available selection of a customization option. The computer system can also cache the at least one edited photo of the at least one available selection of the customization option. Further, the computer system can receive a user request comprising the at least one available selection of the customization option and at least one available selection of at least one additional customization option. The computer system can also stitch the at least one edited photo comprising the at least one available selection of the customization option with at least one additional edited photo comprising the at least one available selection of the at least one additional customization option to render a product photo. Finally, the computer system can cache the requested product photo and send display instructions for the cached requested product photo to a user over a network.

Abstract: A server for generating custom jewelry through a step-by-step customization process can be configured to send display instructions over a network to display a plurality of available selections for a first customization option at a remote computer system. The server can also access a first product photo based on a user selection at the remote computer system of an available selection for the first customization option. Further, the server can send display instructions over a network to display a plurality of available selections for a second customization option at the remote computer system. The server can then access an updated product photo based on a user selection at the remote computer system of an available selection for the second customization option. Finally, the server can send over the network display instructions to the remote computer system for the updated product photo.
