Capture

  • Resource ID : nothing else. It is the active ID and serialised ID.

Replay

  • Resource ID : can be a original ID (serialised ID) or a live ID or the active ID of a created resource.

Replay IDs start from 1000000000000000000.

  • LiveID : go from a serialised ID to active replay ID : original -> live ie. GetLiveID(originalID).
  • OriginalID : go from a live replay ID to a serialised ID : live -> original ie. GetOriginalID(liveID).
  • ReplacedID : replaces the resource of an original ID with a new replay ID : replacement -> original.
    • Used for Shader Editiing.
    • Does not affect GetOriginalID() use GetUnreplacedOriginalID() instead.
    • Does affect GetLiveID().
  • GetUnreplacedOriginalID() : get the original ID for a real ID that may be a replacement. i.e.
    • original ID 123 is live ID 10000000000000000005
    • live ID 10000000000000000005 is replaced with 10000000000000000039
    • calling GetUnreplacedOriginalID with 10000000000000000005 or 10000000000000000039 will return ID 123.
  • In theory could have multiple replacements for the same original ID
    • No asserts if trying to replace an original ID which already has a replacement.
    • Not defined which replacement ID would get used.

TODO

Questions

  • Are replacements usually temporary ie. to support custom replay rendering?
  • When should ReplaceResource() be used during replay or serialised APIs?
  • How to work with replay resources which are recreated during replay ie. RenderPass's?

Thoughts

  • Could add asserts and perhaps parameter/variable name changes in replacement methods to prevent accidental misuse or misunderstanding of the methods.
