PURPOSE:To efficiently generate a curve at high speed by placing a polynomial developing means, Bezier transform means and Bezier generating means on a graphic display device side. CONSTITUTION:A polynomial developing means 1 receives information of a curve to be displayed from a host, and outputs a coefficient of a polynomial, etc. A Bezier converting means 2 receives them, calculates control points Q0-Q3 and outputs them. A Bezier generating means receives them, repeats a curve division by Bezier curve generating method, generates many straight lines and output them. |
