| Abstract: | The problem of measuring the size of unstandard geometric form in computer graphics software is studied. Firstly, the method of pretreating unstandard geometric form is described. Then on the basis of the features of the geometric forms and the interpolation theory, the points selecting method is presented which can measure the size of unstandard geometric form in graphics software. The proposed method is applied to three geometric forms in computer graphics software. The results prove that the simulation is creditable. |
