void random points in unit cube(int n, list& L)
void random point in disc(POINT & p, int R)
as above, but the default value of D is used.
returns a random point with integer x and y-
coordinates in the disc with radius R centered at the
origin. The z-coordinate is zero.
Precondition: R ≤ 2 30 .
void random points in disc(int n, int R, list& L)
returns a list L of n points . . . .
void random point in unit disc(POINT & p, int D = (1 ≪ 30) − 1)
returns a point in the unit disc whose coordinates are
quotients with denominator D. The default value of
D is 2 30 − 1.
void random points in unit disc(int n, int D, list& L)
returns a list L of n points . . . .
void random points in unit disc(int n, list& L)
void random point in ball(POINT & p, int R)
returns a list L of n points . . . . The default value of
D is used.
returns a random point with integer coordinates in
the ball with radius R centered at the origin. In 2d
this function is equivalent to random point in disc.
Precondition: R ≤ 2 30 .
void random points in ball(int n, int R, list& L)
returns a list L of n points . . . .
void random point in unit ball(POINT & p, int D = (1 ≪ 30) − 1)
returns a point in the unit ball whose coordinates are
quotients with denominator D. The default value of
D is 2 30 − 1.
void random points in unit ball(int n, int D, list& L)
returns a list L of n points . . . .
void random points in unit ball(int n, list& L)
void random point near circle(POINT & p, int R)
returns a list L of n points . . . . The default value of
D is used.
returns a random point with integer coordinates that
lies close to the circle with radius R centered at the
origin.
