Graphical data processing

A method of interacting with a remote graphics system over a data network, the remote graphics system being arranged to process graphical data representing an image or graphical model the display of which can be manipulated remotely by user input, the method comprising:

• transmitting to the remote graphics system (i) image quality settings associated with respective manipulation modes, and (ii) control commands indicative of, or from which can be derived, a current manipulation mode;
• and subsequently receiving one or more images back from the remote graphics system, the images having been processed in accordance with the image quality settings for the current manipulation mode.

A system for processing graphical data for transmission to a remote computer via a data network, the graphical data representing an image or graphical model the display of which can be manipulated from the remote computer in real-time in accordance with control commands, wherein the system comprises:

• means for receiving, from the remote computer, image quality settings associated with respective manipulation modes;
• means for identifying a current manipulation mode based on control commands received from the remote computer;
• and means for processing the graphical data in accordance with the image quality settings for the identified current manipulation mode to generate an updated image or set of images for transmission to the remote computer.
