An array is a method of storing data and then later using that stored date
within a function or operation. For example I could predefine a string of
numbers that I want to pass to a pigment statment. I could use an array
to store those string and then later use them in the following way:
#declare Dnum = 6;
#declare Data = array [Dnum][5]
{ {0.60, 0.50, 0.3, 0.1, 0.66},
{0.70, 0.13, 0.4, 0.3, 0.55},
{0.60, 0.17, 0.5, 0.2, 0.44},
{0.70, 0.25, 0.6, 0.4, 0.33},
{0.60, 0.31, 0.7, 0.6, 0.22},
{0.70, 0.50, 0.8, 0.5, 0.11}}
#declare I=0;
#while (I < Dnum)
#declare Acid_Trip =
pigment {
rgbft < Data[I][0], Data[I][1], Data[I][3], Data[I][4], Data[I][5] >
}
#declare I =I + 1;
#end
I could also use similar data to translate an object to a fixed number
of points in space like so:
#declare Dnum = 6;
#declare Data = array [Dnum][3]
{ { 10.60, -10.50, 10.3},
{ -10.70, 10.13, -10.4},
{ 10.60, -10.17, 10.5},
{ -10.70, 10.25, -10.6},
{ 10.60, -10.31, 10.7},
{ -10.70, 10.50, -10.8}}
#declare I = 0;
#while (I < Dnum)
sphere { < Data[I][0], Data[I][1], Data[I][3] >, 1
}
#declare I = I + 1;
#end
The above example should produce six spheres located in space corrosponding
to the numbers stored in the array.
There are many other possibilities with this function and I have only
just begun to explore them myself. In fact it is quite possible that my
syntax is wrong but the basic idea is correct.

How it works depends upon what you are going to do with it. An
array, like a vector is simply an ordered set of numbers. So is
the image POV produces for that matter.
But, once implemented as standard math vectors, Standard array
manipuation functions can be used. In fact, it is the
implementaion of the manipulation functions, the is most
important.
