Title: Generating method for circle
Inventor: YAJIMA AKIO
IPC: G06T11/20
Filed: 1985-10-25
Abstract: PURPOSE:To generate at a high speed an approximate circle having high accuracy, which scarcely causes an error, by providing a mechanism for using a polynomial approximation of a square root calculation with respect to a divided serration angle of a center angle, when generating and displaying a circle by a recurrence formula for using repeatedly an adder/subtracter and a shift register. CONSTITUTION:Information from the outside consists of a center point O, both end points P1, P2 of a circular arc, and a rotating direction omega, and in case when omega is clockwise, processing is always executed counterclockwise by changing P1 and P2.Subsequently, a radius R for calculating a serration angle by an absolute error is calculated, and a center angle alphais calculated by a reverse tangent function. Square of the center angle theta is proportional to the radius R and an approximate error 6 becomes large, but if theta is minute, it coincides with a serration angle (c), therefore, an optimum value (shift number) is selected by the radium R. A repeating number of a recurrence formula is a positive integer value which has discarded a value obtained by dividing the center angle ' by the serration angle (c), a square root is made approximate by a polynomial, a relative coordinate value to the center O of a start point being an initial value of the recurrence formula is set, and a control operation is executed repeatedly. Next, an absolute coordinate to the center point O is derived, and linear picture drawing is executed.
