摘要
Interfaces of the three-dimensional graphics system using parametric modeling unit for modeling the high-order objects on a surface, and a rendering system of the polygon base to render the modeled object to the polygon for display. To form an input device for receiving data representing a higher-order surface patches of a single leaf patch data representative of the patch in the subdivision of the first level by processing the data, and the interface, said data at least subdivision unit for forming a sub-leaf patch data representative of the patch subdivision of the second level to further processing (18), the first representing the vertices describing tessellation polygon the leaf patch is obtained from the leaf patch data values of multiple transducers and for determining from the sub-leaf patch data to a second value representing the vertices describing tessellation polygon the subpatch and (20)) and the first It includes a coupler for forming a leaf polygon data defining the vertices of the polygon subdivision level of the first by combining the values of the second plurality of, and an output device for outputting the leaf polygon data .
