Patent ID: 7088362

Claim:
A graphic computing method comprising: dividing a unit shape of a surface of an object present in a three-dimensional space into a plurality of subpolygons two-dimensionally arranged in terms of their neighboring relationship and having an arbitrary size, to generate a subpolygon mesh; executing at least one of arithmetic operations of vertex displacement, coordinate conversion, coloring, and shading using various programs in units of vertexes of subpolygons of the subpolygon mesh to obtain parameters required for drawing; computing drawing data in units of pixels on the basis of the parameters and picture data for texture mapping; storing in a frame memory the drawing data as picture data together with at least data for texture mapping required for computing the drawing data; reading out at least the picture data for texture mapping from the frame memory via a frame memory readout route; reading at least the picture data for texture mapping corresponding to each vertex of the subpolygon mesh from the frame memory via the frame memory readout route; and computing the parameters required for drawing in units of pixels of the subpolygons for each vertex of the subpolygon meshes using the read data.
