Detailed Description

Maps a single subresource region of tiles for a source resource to individual tiles of a destination heap. Used for cases where tiles are pool allocated from the heap and assigned individually to tiles of the source resource.

This was written specifically to enable mip streaming, which is the only system currently designed to utilize it.

The request can either map tiles from the source resource to tiles in the destination resource, or it can clear the existing mappings on the source resource to null.

  • To map against the heap, specify a destination heap and the tile association map.
  • To clear existing mappings, leave the destination parts null / empty.
