PURPOSE:To realize smooth interpolation by simple and quick processing by successively calculating the middle point of a segment connecting between vertexes by 1st-3rd arithmetic means. CONSTITUTION:The coordinate data of 1st-3rd points successively set up on a continuous curve inputted from an input means 1 and the coordinate data of the 1st vertex to be the symmetrical point of the middle point of the segment connecting the 1st and 3rd points about the 2nd point are stored in a 1st storage means 2. The 1st arithmetic means 3 calculates a 11-th vertex to be the middle point of the segment connecting the 1st point and the 1st vertex and the 2nd arithmetic means 4 calculates a 12-th middle point functioning as the middle point of the segment connecting the 1st point and the 2nd point. The 3rd arithmetic means 5 calculates the middle point of the segment connecting the 11-th vertex and the 12-th middle point. The middle point is the interpolation point between the 1st and 2nd points. The coordinate data of the interpolation point are stored in a 2nd storage means 6 and outputted by an output means 7. |
