Abstract
A method and apparatus of rendering object oriented image data into a frame buffer of an imaging device using a set of rendering state information is provided. Object oriented image data is read into the imaging device together with an imaging operator associated with the object oriented image data. The object type of the imaging operator is determined. Based on the object type of the imaging operator, a set of rendering state information is selected from a plurality of sets of rendering state information stored beforehand in the imaging device. Using the rendering state information, the imaging device renders the object oriented image data into a frame buffer of the imaging device for ready display. Each different object type encountered by the imaging device, a renderstate pointer is loaded with index information so that an appropriate one of the plurality of sets of rendering state information can be quickly and easily accessed for integration into the current graphic state information set for rendering differing object types on the fly.
