    • PURPOSE:To provide a method for inputting especially conventional shape definition data and distinctively adding an outline, an opening side and a ridgeline for three-dimensional surface display which is gray-level-displayed. CONSTITUTION:In a display device 1, a formula space processing part 6 which executes the display processing of a prestage in terms of formula is provided with an outline detection part 11 checking the number of appearing times of the matched side by the comparison of the both end coordinate values of the respective sides and detecting the sides becoming the outline, the opening side and the ridgeline as against polygonal data. A picture space processing part 8 executing the display processing of a poststage in terms of the picture erases a hidden line and executes an overlap processing to a surface picture. Thus, the outline, the opening side and the ridgeline can securely be separated and detected, and they can be displayed in accordance with respective attributes. Thus, the easily understandable display picture can be obtained. At that time, shape definition data can be set to conventional one as it is.

    • PROBLEM TO BE SOLVED: To provide a system for identifying each paper, and for reusing the digitized information by using paper in an electronic pen system for digitizing characters or graphics handwritten on paper by reading dot patterns printed on paper with an electronic pen. SOLUTION: A plurality of dot pattern information printed on paper is stored in a computer system, and unused dot pattern information is assigned when a form is printed, and the dot patterns and form information are linked, and the dot patterns and the form are printed on sheets so that paper can be prepared. As for contents filled in the paper, the task information is digitized by using a conventional technology. The digitized task information and the form information are linked to each other and stored. Furthermore, when the form whose reuse is necessary is printed, unused dot patterns and the task information linked to the form information are extracted, and the form is printed according to a form format.
