Patent ID: 7898549

Claim:
A method for creating a sequence of rendered images, comprising: resetting a first set of values defining a first bounding area memory connected with a graphics pipeline; creating a first rendered image in a first memory buffer from a first set of rendering commands defining a first set of primitives; modifying the first set of values defining the first bounding area memory in response to the first set of rendering commands; displaying the first rendered image from the first memory buffer; storing the first set of values defining the first bounding area memory as a first bounding area value in a memory; resetting a second set of values defining a second bounding area memory connected with the graphics pipeline in preparation for a second rendered image; creating the second rendered image in a second memory buffer from a second set of rendering commands defining a second set of primitives; modifying the second set of values defining the second bounding area memory in response to the second set of rendering commands; displaying the second rendered image from the second memory buffer; and clearing a portion of the first memory buffer corresponding to the first bounding area value.
