  • Curve-generating device for visual display of symbols on a cathode-ray screen
    Patent number: 4314351
    Abstract: The curve-generating device serves in particular to produce signals relating to a circular line from simple algorithms. The device comprises means for computing a parameter .DELTA.L defined by ##EQU1## where U is an elementary vector, .theta. is the angle at the center of a polygon of side U+.DELTA.L circumscribed about the circle R, and processing logic circuits for determining the polar direction P.sub.n of the plotted line according to the relation: ##EQU2## where.DELTA..sub.n-1 =1 in respect of x.sub.n-1 .gtoreq.U andx.sub.n =x.sub.n-1 +.DELTA.L.multidot..DELTA..sub.n-1 -U.multidot..DELTA..sub.n-1.
