FFX_BREADCRUMBS_PRINT_NOT_STARTED_LISTS = (1<<1) – A bit indicating that command lists that haven’t started execution on GPU yet will be expanded during status printing (otherwise their entries will be collapsed).
FFX_BREADCRUMBS_PRINT_FINISHED_NODES = (1<<3) – A bit indicating that nested markers which already have finished execution will be expanded during status printing (otherwise they will merged into top level marker).
FFX_BREADCRUMBS_PRINT_NOT_STARTED_NODES = (1<<4) – A bit indicating that nested markers which haven’t started execution yet will be expanded during status printing (otherwise they will merged into top level marker).

FidelityFX Breadcrumbs library.
Global functions
ffxBreadcrumbsContextCreate
FFX_API FfxErrorCode ffxBreadcrumbsContextCreate (
FfxBreadcrumbsContext * pContext,
const FfxBreadcrumbsContextDescription * pContextDescription
)Create a FidelityFX Breadcrumbs context from the parameters programmed to the FfxBreadcrumbsContextDescription structure.
The context structure is the main object used to interact with the Breadcrumbs API, and is responsible for the management of the internal buffers used by the Breadcrumbs algorithm. For each provided queue there will be created a buffer that will hold contents of the saved markers, awaiting for retrieval per call to ffxBreadcrumbsPrintStatus()
When choosing the number of frames to save markers for, specified in the frameHistoryLength field of FfxBreadcrumbsContextDescription, typically can be set to the number of frames in flight in the application, but for longer history it can be increased.
Buffers for markers are allocated at fixed size, allowing for certain number of markers to be saved in them. The size of this buffers are determined by maxMarkersPerMemoryBlock field of FfxBreadcrumbsContextDescription. When needed new ones are created but to avoid multiple allocations you can estimate how many markers will be used in single frame.
The FfxBreadcrumbsContext should be destroyed when use of it is completed, typically when an application is unloaded. To destroy the Breadcrumbs context you should call ffxBreadcrumbsContextDestroy.
Parameters:
|
pContext |
A pointer to a |
|
pContextDescription |
A pointer to a |

ffxBreadcrumbsRegisterCommandList
FFX_API FfxErrorCode ffxBreadcrumbsRegisterCommandList (
FfxBreadcrumbsContext * pContext,
const FfxBreadcrumbsCommandListDescription * pCommandListDescription
)Register new command list for current frame FidelityFX Breadcrumbs operations.
After call to ffxBreadcrumbsStartFrame() every previously used list has to be registered again.
Parameters:
|
pContext |
A pointer to a |
|
pCommandListDescription |
A pointer to a |
Return values:
|
FFX_OK |
The operation completed successfully. |

ffxBreadcrumbsRegisterPipeline
FFX_API FfxErrorCode ffxBreadcrumbsRegisterPipeline (
FfxBreadcrumbsContext * pContext,
const FfxBreadcrumbsPipelineStateDescription * pPipelineDescription
)Register new pipeline state to associate later with FidelityFX Breadcrumbs operations.
Information about pipeline is preserved across frames so only single call after creation of pipeline is needed.
Parameters:
|
pContext |
A pointer to a |
|
pPipelineDescription |
A pointer to a |
Return values:
|
FFX_OK |
The operation completed successfully. |

FfxBreadcrumbsContext * pContext,
FfxCommandList commandList,
FfxPipeline pipeline
)Associate specific pipeline state with following FidelityFX Breadcrumbs markers.
When recorded commands use specific pipelines you can save this information, associating said pipelines with recorded markers, so later on additional information can be displayed when using ffxBreadcrumbsPrintStatus(). To reset currently used pipeline just pass NULL as pipeline param.
Parameters:
|
pContext |
A pointer to a |
|
commandList |
Previously registered command list. |
|
pipeline |
Previously registered pipeline. |

A pointer to a |
|
commandList |
Previously registered command list. |
