摘要： PURPOSE:To obtain an easily usable image forming method matched with human's plotting sense or the like by changing the degree of determination of a shape model in accordance with the degree of change in an inputted shape model and distinguishably displaying the display format of the shape model to be displayed on a screen in accordance with the degree of determination. CONSTITUTION:When a designer inputs a shape model to be deleted from an input device 1, a control device refers the degree of determination in the 'existence' of the selected shape model from a storage device 2 and deleting processing is distinguished by the degree of determination. When the degree of determination of 'existence' is high, the control device 3 inquires of the designer about the approval of practical deletion of the shape model, and when the designer approves the deletion, deletes the shape model to be deleted from the storage device 2 and erases the shape model concerned from an output device 3. When the designer rejects the deletion, the degree of determination of the shape model in the storage device 2 is reduced by the control devices 3 and the display width of a line is thined by the output device 3. Thus, optional operation can be attained at the initial stage of design and designer's operability can be improved.

摘要： PURPOSE:To display a piercing line by dividing a triangle into three small ones with line segments connected from a dividing point to the three vertexes of the triangle when the point exists in the triangle, but dividing it into two smaller triangles when said point is present on one side of the triangle with a line segment connected from a dividing point to a vertex. CONSTITUTION:When that one end of a piercing line is brought into contact with the side of a triangle is judged as the case (a), the triangle 3 is divided into three smaller ones with the end point of piercing line existing inside the triangle 3 for the dividing point 4. Next, as shown in the figure (d), the other end of the piercing line is made as a dividing point 4, and all the triangles that include the side on which the point 4 exists are halved. Also, as shown in the figure (b), when the piercing line is included inside the triangle 3, the triangle 3 is divided into three divisions with the one end of the piercing for a dividing point inside the triangle 3 as shown in the figure (e). Then, as shown in the figure (f), the triangle is divided into three division with the other end of the piercing line as the dividing point 4.
