Technologies are generally described for methods and systems effective to generate a scene image. In an example, a processor may receive a first rendered object from a first device and may further store the first rendered object in a memory. The first rendered object may be based on object data and may include first attribute data of the object data. The processor may further receive a request from a second device to generate the scene image. The scene image may include an object image of a second rendered object that may be based on the object data and may include second attribute data of the object data. The processor may further compare the second attribute data with the first attribute data to determine a match value. The processor may further determine whether to select the stored first rendered object to generate a scene image based on the match value.

When a picture displayed on a client device is enlarged, the client device may be configured to insert new pixels between two adjacent pixels in the picture. When actual values of the new pixels are stored on a server, the client device may submit a request to the server for actual values of the new pixels. Responsive to the request, the server may first calculate interpolation values in accordance with the same interpolation algorithm and then calculate a difference value based on the interpolation values and the actual values stored on the server. If the calculated difference value is greater than a threshold value, the server may transmit the actual values for the new pixels to the client device. Otherwise, the server may instruct the client device to calculate the interpolation values.
