Detailed Description

template<typename T>
struct blender::GroupedSpan< T >

References many separate spans in a larger contiguous array. This gives a more efficient way to store many grouped arrays, without requiring many small allocations, giving the general benefits of using contiguous memory.

Note

If the offsets are shared between many GroupedSpan objects, it will be more efficient to retrieve the IndexRange only once and slice each span.
