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.

Abstract: A computer graphics system generates pixel values for pixels in an image of objects in a scene, using strictly-deterministic low-discrepancy sequences, illustratively Halton sequences, as sample points for evaluating integrals which are used to simulate a number of computer graphic techniques. The computer graphics system uses the low-discrepancy sequence to ensure that the sample points are evenly distributed over a respective region or time interval, thereby reducing error in the image which can result from clumping of such sample points which can occur in the Monte Carlo technique. In particular, the invention facilitates the generation of images of improved quality when using the same number of sample points at the same computational cost as in the Monte Carlo technique.

Abstract: A computer graphics system generates a three-dimensional model of an object in an interactive manner under control of an operator. An initial model for the object to be modeled is displayed to the operator as illuminated from a particular illumination direction and projected onto an image plane. The operator can update shading of a pixel on the image plane, and, based on the updated shading, the computer graphics system generates an updated normal vector for the updated pixel, which identifies the normal of the surface of the object projected onto the updated pixel. Using the updated normal vector field and a height field, which represents the height of the respective portion of the object as projected onto the respective pixels of the image plane, the computer graphics system generates an updated height value for the updated pixel, thereby to update the height field.
