Abstract: A method for displaying a three-dimensional scene in which some objects are blurred because of motion comprises the steps of categorising the objects in a scene into two sets, a first set containing objects to be blurred and a second set containing objects not to be blurred. The first set of objects is rendered directly to a first buffer, the render time period is then divided into a plurality of time slices and for each time slice each object in the second set is rendered to the first buffer, a scene is accumulated from the first buffer to an accumulation buffer to be displayed. Thus, static objects (non-blurred) are rendered only once and moving objects (blurred) are rendered over a series of time slices. Preferably the categorising step includes determining if a motion vector is associated with an object.
