| Abstract: | It is proved that affine deformation can be summarized as affine transformation; The 2 dimensional and 3 dimensional affine deformations are studied again on the basis of affine transformation. A set of precise formulas which can be applied to both large deformation and small deformation are derived . From the geometric point of view this paper can be generatized as the further study of ellipse and ellipsoid. |
