SYSTEM AND METHOD FOR IMPROVING GRAPHIC ROTATION RENDERING

PROBLEM TO BE SOLVED: To realize a system and a method for rendering graphic rotation more easily. SOLUTION: This processor works on a matrix M through the use of a matrix operator having the quality of coincidence with rotation and of attraction to the rotation. The matrix operator is adapted plural times in order to attain larger error attenuation. The processor or a graphic accelerator calculates image graphic rendering through the use of a result matrix L which is obtained by the adaptation of the matrix operator. A first approximate rotation matrix for expressing an orientation before a graphic object is multiplied by the second approximate rotation matrix expressing the desired rotation to be added to the graphic object to obtain the matrix M expressing the updated orientation of the graphic object.
