void
random point on paraboloid(POINT & p, int maxc)
returns a point (x, y, z) with x and y random integers
in the range [−maxc .. maxc], and z = 0.004 ∗ (x ∗ x +
y ∗y)−1.25∗maxc. The function does not make sense
in 2d.
void random points on paraboloid(int n, int maxc, list& L)
returns a list L of n points . . . .
void lattice points(int n, int maxc, list& L)
returns a list L of approximately n points. The points
have integer coordinates id/maxc for an appropriately
chosen d and −maxc/d ≤ i ≤ maxc/d.
void random points on diagonal(int n, int maxc, list& L)
generates n points on the diagonal whose coordinates
are random integer in the range from −maxc to maxc.
