ABSTRACT:
There is described a computer graphics apparatus having a data store for storing data defining a computer model comprising a plurality of three-dimensional objects, the computer model varying over time. The computer graphics apparatus processes the data defining the computer model to generate display data defining a sequence of two-dimensional display images, which change as the computer model varies over time, for display to a user. The computer graphics apparatus is also able to generate static image data corresponding to a displayed image in response to an initiation signal. In order to ensure that the static image data corresponds to the displayed image on receipt of the initiation signal, the computer apparatus is arranged to detect modification of the computer model subsequent to the reception of the initiation signal and to store recovery data enabling the computer model corresponding to the display image on receipt of the initiation signal to be generated using the computer model as modified subsequent to the reception of the initiation signal.
