Image data generating method for displaying computer generated object on displaying device, involves rendering divided polygon area networks with shaded value for receiving image data in display devic

The method involves supplying polygon area networks with amount of vertex for representing an object. The polygon area networks are divided according to a classification procedure e.g. butterfly-classification procedure. A normal amount of vertex is determined, where normal vertex is assigned to the amount of vertex according to the classification procedure. The divided polygon area networks are rendered with a shaded value for receiving image data in a display device, where the normal vertex is provided as calculated dataset. The classification procedure is selected from loop-classification procedure, butterfly-classification procedure, Clark algorithm classification procedure, dynamic-classification procedure and Doo-Sabin-classification procedure. Independent claims are also included for the following: (1) a computer program-product with program code for performing a method for generating image data (2) a computer program stored in a data storage medium for performing a method for generating image data.
