Patent ID: 7746346

Claim:
A method of rendering three-dimensional graphics data, the method comprising: dividing initially inputted first graphics data into a first static object and a first dynamic object; performing a first rendering process with respect to the first static object; updating a buffer with a result of the rendering, the rendering result including rendered color information or depth information with respect to the first graphics data; performing a transformation process; performing a portion of a second rendering process with respect to the first dynamic object; determining an updating area; storing a portion of the rendering result corresponding to the updating area in a predetermined storage unit; performing a remaining portion of the second rendering process with respect to the first dynamic object; updating the buffer with the result of the second rendering process with respect to the first dynamic object; outputting a first image whose rendering is completed; restoring the rendering result of the updating area to the buffer by referring to the storage unit to create a restored buffer; and utilizing the restored buffer as a second rendering result of subsequently inputted second graphics data.
