Detailed Description

Scene query filtering callbacks.

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

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

The prefilter may overwrite the copy of filterFlags passed in the query's PxSceneQueryFilterData, in order to specify PxSceneQueryFilterFlag::eBACKFACE and PxSceneQueryFilterFlag::eMESH_MULTIPLE on a per-shape 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.

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

Filtering calls 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.
