Collections vs. Arrays

Both arrays and collections are used to hold more than one value or object. With Softimage, collections are normally used to hold several objects, while arrays are normally used to hold data, such as point coordinate values.

Both arrays and collections identify their members by an index number, which starts at 0. So the item at index 0 in a collection or array is the first member, the item at index 1 is the second member, and so on.
