Detailed Description

A tiny set of integers, which provides an indirection mapping from the conceptual space of an HdRprim's resources (topological, primvar & instancing) to the index within HdBufferArrayRangeContainer, where the resource is stored.

Each HdDrawItem contains a HdDrawingCoord, with the relevant compositional hierarchy being:

HdRprim | +–HdRepr(s) | | | +–HdDrawItem(s)-------—. | | | | +–HdDrawingCoord | | | (mapping provided by HdDrawingCoord) +–HdRprimSharedData | | | +–HdBARContainer <-----—+

Having this indirection provides a recipe for how to configure a drawing coordinate, which is a bundle of HdBufferArrayRanges, while they are shared or not shared across different representations constructed on the same prim.

HullRepr ------— Rprim ------— RefinedRepr | | | DrawItem | DrawItem | | | DrawingCoord Container DrawingCoord constant ----—> [ 0 ] <---— constant vertex ----—> [ 1 ] topology ----—> [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ] [ 7 ] [ 8 ] <---— vertex (refined) [ 9 ] <---— topology (refined) ... instance level=0 —> [ k ] instance level=1 —> [k+1] instance level=2 —> [k+2]
