Detailed Description

The render delegate can create an object of type HdRenderParam, to pass to each prim during Sync(). Storm uses this class to house global counters amd flags that assist invalidation of draw batch caches.

HDST_API void HdStRenderParam::DecreaseMaterialTagCount

(

const TfToken &

materialTag

Unregister that there is an rprim with given materialTag.

HDST_API void HdStRenderParam::DecreaseRenderTagCount

(

const TfToken &

renderTag

Render tag tracking.

Does render index have rprims with given renderTag?

HDST_API bool HdStRenderParam::HasMaterialTag

(

const TfToken &

materialTag

)

const

Material tag tracking.

Does render index have rprims with given materialTag? Note that for performance reasons and ease of implementation (HdRprimSharedData::materialTag initializes to the default material tag), this always returns true for the default (and empty) material tag.

HDST_API void HdStRenderParam::IncreaseMaterialTagCount

(

const TfToken &

materialTag

)

Register that there is an rprim with given materialTag.

HDST_API void HdStRenderParam::IncreaseRenderTagCount

(

const TfToken &

renderTag

)

Register that there is an rprim with given renderTag.

HDST_API void HdStRenderParam::MarkDrawBatchesDirty

(

)

Draw items cache and batch invalidation.

Marks all batches dirty, meaning they need to be validated and potentially rebuilt.

HDST_API void HdStRenderParam::MarkGeomSubsetDrawItemsDirty

(

)

Marks geom subsets draw items dirty, meaning that the draw items associated with the collection of a render pass need to be re-gathered.

HDST_API void HdStRenderParam::MarkMaterialTagsDirty

(

)

Marks material tags dirty, meaning that the draw items associated with the collection of a render pass need to be re-gathered.

void HdStRenderParam::SetGarbageCollectionNeeded ( )

inline

Garbage collection tracking.
