Class description This class is a union of the following tuple types, any of which can be used as the indexes slot of a render-set to select elements from a vertex-array for rendering.
•
An index-range value submits a sequential slice of a vertex array for rendering.
•
An index-elements value submits vertex array elements in an order specified by an array of indexes.
•
A multi-index-range value submits multiple sequential slices of a vertex array.
•
A multi-index-elements value submits multiple separate lists of indexed vertex array elements.

Specialized arrays of uchar, ushort, or uint elements may also be used directly as arrays of indexes.
