CUBE_GRID is a C library which generates a grid of points over the interior of a cube in 3D.
The 3D cube is the set of points (X(1),X(2),X(3)) such that:
A(I) <= X(I) <= B(I)
For each dimension I, a set of parameters is input:
The centering options allow the user to control the centering of the equally spaced points. This is easiest to illustrate if we look at a 1 dimensional case and assume A = 0 and B = 1. Then, using NS = 4, the centering options will produce 4 equally spaced points as follows:
