d3 rat point random d3 rat point in unit cube(int D = 16383)
returns a point whose coordinates are random rationals
of the form i/D where i is a random integer in the range
[0 .. D]. The default value of D is 2 14 − 1.
void random d3 rat points in unit cube(int n, int D, list& L)
returns a list L of n points . . . .
void random d3 rat points in unit cube(int n, list& L)
d3 rat point random d3 rat point in ball(int R)
as above, but the default value of D is used.
returns a random point with integer coordinates in the
ball with radius R centered at the origin.
Precondition: R ≤ 2 14 .
void random d3 rat points in ball(int n, int R, list& L)
returns a list L of n points . . . .
d3 rat point random d3 rat point in unit ball(int D = 16383)
returns a point in the unit ball whose coordinates are
random rationals of the form i/D where i is a random
integer in the range [0 .. D]. The default value of D is
2 14 − 1.
void random d3 rat points in unit ball(int n, int D, list& L)
returns a list L of n points . . . .
void random d3 rat points in unit ball(int n, list& L)
d3 rat point random d3 rat point in disc(int R)
returns a list L of n points . . . . 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. In 2d this is the same
as the function random rat point in ball.
Precondition: R ≤ 2 14 .
void random d3 rat points in disc(int n, int R, list& L)
d3 rat point random d3 rat point on circle(int R)
returns a list L of n points . . . .
returns a random point with integer coordinates that
lies close to the circle with radius R centered at the
origin.
void random d3 rat points on circle(int m, int R, list& L)
returns a list L of n points . . . .
