61// Class: SoArray
62//
63// Array group node: creates an IxJxK array. Each element in the
64// array is drawn by traversing all of the children of this node,
65// saving and restoring state before and after each element. I, J,
66// and K are given by the numElements1, numElements2, and
67// numElements3 fields. The 3D vector separating the centers of
68// adjacent elements in each of the three directions is given by
69// separation1, separation2, and separation3. The origin field
70// indicates whether the array is positioned with the current
71// object-space origin at the center of the first element, the last
72// element, or at the center of all elements.
