These functions write geometry to text files, one line per geometric primitive. Each line has the form “x y z” for points or “x y z r” for spheres. We can easily add general dimension support if requested.. Lines beginning with "#" are treated as comments.

These functions generate vector objects. Some of the methods, those with random in their name, generate a single vector chosen uniformly from the specified domain. Others, the cover methods, generate a set of points distributed (somewhat) evenly over the domain.

Vector2D
- Note
- This class is a geometric primitive. Also, this class is not not initialized by its default constructor.

template<class It >
The distance between b and e must be equal to D.
Definition at line 103 of file VectorD.h.
Returns a unit vector pointing at the same direction as this vector.
- Note
- If the magnitude of this vector is smaller than 1e-12 (an arbitrarily selected small number), returns a unit vector pointing at a random direction
Definition at line 201 of file VectorD.h.
Return the ith Cartesian coordinate. In 3D use [0] to get the x coordinate etc.

Return the ith Cartesian coordinate. In 3D use [0] to get the x coordinate etc.
Definition at line 171 of file VectorD.h.
Note that this is not very reliable and probably should not be used.
