Abstract

A server for use in connection with a network including at least one client and a communication link interconnecting the client and server. The server comprises a user interaction control module, an image rendering module and an interface. The image rendering module is configured to render, from three-dimensional scene data representing a scene, a two-dimensional image. The interface configured to transmit the two-dimensional image over the communication link to the client. The user interaction control module is configured to regulate interactions between the server, in particular the image rendering module, and respective clients who may be using the server concurrently to control images in which customizations requested by, for example, respective clients are rendered.

B. a connection manager module configured to connect the selected operators into the operator graph.

10. A server as defined in claim 9 in which scenes for which images are to be rendered are selected in response to requests therefor, and in which a request can include scene customization information requesting at least one customization to the scene, the user manager module being configured to select operators for use in the operator graph in response to the image requested by and scene customization information contained in a request.

11. A server as defined in claim 8 in which the image rendering module comprises:

A. a scene database configured to store scene data representing at least a portion of the scene for which an image is to be rendered

B. a customization module configured to customize the scene data contained in the scene database;

C. a rendering engine module configured to utilize the scene data in the scene database in connection with rendering at least a portion of an image; and

D. a job manager module configured to control the customization module and the rendering module in connection with execution of said at least one operator in the operator graph.

12. A server as defined in claim 11 in which, in response to execution of said at least one operator, the job manager module is configured to establish at least one job, the at least one job being executable by at least one of said customization module or the rendering engine module.

13. A server as defined in claim 12 in which, in response to execution of said at least one operator, the job manager module is configured to establish a plurality of jobs in a job dependency graph, each job being executable by at least one of said customization module or the rendering engine module, and select ones of the jobs in the graph for execution.

14. A server as defined in claim 13 in which the job manager module is configured to select ones of the jobs for execution in relation to respective job cost values associated with the respective jobs.

15. A server as defined in claim 14 in which the job manager module is configured to assign respective job cost values in relation to an estimate of server resources used during execution of the associated jobs.

16. A computer program product for use in connection with a computer to form a server for use in a network, the network including at least one client and a communication link interconnecting the client and server, the computer program product comprising a computer-readable medium having encoded thereon:

A. an image rendering module configured to enable the computer to render, from three-dimensional scene data representing a scene, a two-dimensional image; and

B. an interface module configured to enable the computer to transmit the two-dimensional image over the communication link to the client.

17. A computer program product as defined in claim 16 further comprising a user interaction control module configured to enable the computer to control interactions with said at least one client in connection with rendering of the image from the scene data.
