Typedef Documentation

typedef PxSceneQueryHitType::Enum(* PxBatchQueryPostFilterShader)(PxFilterData filterData0, PxFilterData filterData1, const void *constantBlock, PxU32 constantBlockSize, const PxSceneQueryHit &hit)

Batched query postfiltering shader.

Custom filtering logic for batched query intersection candidates. If an intersection candidate object passes the data based filter (see PxSceneQueryFilterData), the filtering shader run on request (see PxSceneQueryFilterData.flags)

If the PxSceneQueryFilterFlag::ePOSTFILTER flag is set, the PxBatchQueryPostFilterShader function is called for each intersection point to determine touch/block status. This overrides any touch/block status returned from the PxBatchQueryPreFilterShader for this shape.

Filtering shaders are not in order along the query direction, rather they are processed in the order in which candidate shapes for testing are found by PhysX' scene traversal algorithms.

Parameters:

`[in]`	filterData0	The custom filter data of the query
`[in]`	filterData1	The custom filter data of the shape
`[in]`	constantBlock	The constant global filter data (see PxBatchQuery)
`[in]`	constantBlockSize	Size of the global filter data (see PxBatchQuery)
`[in]`	hit	declaration.

typedef PxSceneQueryHitType::Enum(* PxBatchQueryPreFilterShader)(PxFilterData filterData0, PxFilterData filterData1, const void *constantBlock, PxU32 constantBlockSize, PxSceneQueryFilterFlags &filterFlags)

Batched query prefiltering shader.

Custom filtering logic for batched query intersection candidates. If an intersection candidate object passes the data based filter (see PxSceneQueryFilterData), the filtering shader run on request (see PxSceneQueryFilterData.flags)

If PxSceneQueryFilterFlag::ePREFILTER is set, the PxBatchQueryPreFilterShader runs before precise intersection testing. If this function returns PxSceneQueryHitType::eTOUCH or PxSceneQueryHitType::eBLOCK, precise testing is performed to determine intersection point(s).

The PxBatchQueryPreFilterShader may overwrite the copy of filterFlags passed in, in order to specify PxSceneQueryFilterFlag::eBACKFACE and PxSceneQueryFilterFlag::eMESH_MULTIPLE on a per-shap basis. Changes apply only to the shape being filtered, and changes to other flags are ignored.

If PxSceneQueryFilterFlag::ePREFILTER is not set, precise intersection testing is performed with the PxSceneQueryFilterFlag::eBACKFACE and PxSceneQueryFilterFlag::eMESH_MULTIPLE flags from the filterFlags field.

Filtering shaders are not in order along the query direction, rather they are processed in the order in which candidate shapes for testing are found by PhysX' scene traversal algorithms.

Parameters:

`[in]`	filterData0	The custom filter data of the query
`[in]`	filterData1	The custom filter data of the second object
`[in]`	constantBlock	The constant global filter data (see PxBatchQuery)
`[in]`	constantBlockSize	Size of the global filter data (see PxBatchQuery)
`[out]`	filterFlags	Flags giving additional information on how an accepted pair should get processed
