摘要
A value of a parameter t corresponding to the adjacent next plot point on a bit map memory in an x or y direction is calculated, one of the x or y coordinate values of a current plot point is changed by 1 to calculate a coordinate in the same direction of the next plot point, and the other coordinate of the next plot point is calculated on the basis of an approximated parameter t and cubic curve, thereby plotting the next plot point on the bit map memory.
