virtual void PxBatchQuery::execute ( )

pure virtual

Executes batched queries.

virtual const void* PxBatchQuery::getFilterShaderData ( ) const

pure virtual

Gets the shared global filter data in use for this scene query.

Returns: Shared filter data for filter shader.

See Also: getFilterShaderDataSize() PxBatchQueryDesc.filterShaderData PxBatchQueryPreFilterShader, PxBatchQueryPostFilterShader

virtual PxU32 PxBatchQuery::getFilterShaderDataSize ( ) const

See Also: getFilterShaderData() PxBatchQueryDesc.filterShaderDataSize PxBatchQueryPreFilterShader, PxBatchQueryPostFilterShader

virtual PxClientID PxBatchQuery::getOwnerClient ( ) const

pure virtual

It is not possible to change this value after creating the scene query.

See Also: PxBatchQueryDesc::ownerClient

virtual PxBatchQueryPostFilterShader PxBatchQuery::getPostFilterShader ( ) const

pure virtual

Gets the postfilter shader in use for this scene query.

Returns: Postfilter shader.

See Also: PxBatchQueryDesc.preFilterShade PxBatchQueryPostFilterShader

virtual PxBatchQueryPreFilterShader PxBatchQuery::getPreFilterShader ( ) const

pure virtual

Gets the prefilter shader in use for this scene query.

Returns: Prefilter shader.

See Also: PxBatchQueryDesc.preFilterShade PxBatchQueryPreFilterShader

virtual bool PxBatchQuery::getRunOnSpu ( )

pure virtual

PS3 only. Returns true if this query should run on SPU.

See Also: PxBatchQueryDesc

virtual const PxBatchQueryMemory& PxBatchQuery::getUserMemory ( )

pure virtual

Gets the user memory pointers.

See Also: PxBatchQueryDesc

virtual void PxBatchQuery::overlap	(	const PxGeometry &	geometry,
		const PxTransform &	pose,
		PxU16	maxTouchHits = `0`,
		const PxQueryFilterData &	filterData = `PxQueryFilterData()`,
		void *	userData = `NULL`,
		const PxQueryCache *	cache = `NULL`
	)

pure virtual

Performs an overlap test of a given geometry against objects in the scene, returns results in PxBatchQueryMemory::userOverlapResultBuffer specified at PxBatchQuery creation time or via PxBatchQuery::setUserMemory call.

Note: Filtering: returning eBLOCK from user filter for overlap queries will cause a warning (see PxQueryHitType).

Parameters

[in]	geometry	Geometry of object to check for overlap (supported types are: box, sphere, capsule, convex).
[in]	pose	Pose of the object.
[in]	maxTouchHits	Maximum number of hits to record in the touch buffer for this query. Default=0 reports a single blocking hit. If maxTouchHits is set to 0 all hits are treated as blocking by default.
[in]	filterData	Filtering data and simple logic. See PxQueryFilterData PxBatchQueryPreFilterShader, PxBatchQueryPostFilterShader
[in]	userData	User can pass any value in this argument, usually to identify this particular query
[in]	cache	Cached hit shape (optional). Query is tested against cached shape first. If no hit is found the ray gets queried against the scene. Note: Filtering is not executed for a cached shape if supplied; instead, if a hit is found, it is assumed to be a blocking hit. Note: Using past touching hits as cache will produce incorrect behavior since the cached hit will always be treated as blocking.

Note: eBLOCK should not be returned from user filters for overlap(). Doing so will result in undefined behavior, and a warning will be issued.; If the PxQueryFlag::eNO_BLOCK flag is set, the eBLOCK will instead be automatically converted to an eTOUCH and the warning suppressed.; This query call writes to a list associated with the query object and is NOT thread safe (for performance reasons there is no lock and overlapping writes from different threads may result in undefined behavior).

virtual void PxBatchQuery::raycast	(	const PxVec3 &	origin,
		const PxVec3 &	unitDir,
		PxReal	distance = `PX_MAX_F32`,
		PxU16	maxTouchHits = `0`,
		PxHitFlags	hitFlags = `PxHitFlag::ePOSITION\|PxHitFlag::eNORMAL\|PxHitFlag::eDISTANCE`,
		const PxQueryFilterData &	filterData = `PxQueryFilterData()`,
		void *	userData = `NULL`,
		const PxQueryCache *	cache = `NULL`
	)

pure virtual

Performs a raycast against objects in the scene, returns results in PxBatchQueryMemory::userRaycastResultBuffer specified at PxBatchQuery creation time or via PxBatchQuery::setUserMemory call.

Note: Touching hits are not ordered.; Shooting a ray from within an object leads to different results depending on the shape type. Please check the details in article SceneQuery. User can ignore such objects by using one of the provided filter mechanisms.

Parameters

[in]	origin	Origin of the ray.
[in]	unitDir	Normalized direction of the ray.
[in]	distance	Length of the ray. Needs to be larger than 0.
[in]	maxTouchHits	Maximum number of hits to record in the touch buffer for this query. Default=0 reports a single blocking hit. If maxTouchHits is set to 0 all hits are treated as blocking by default.
[in]	hitFlags	Specifies which properties per hit should be computed and returned in hit array and blocking hit.
[in]	filterData	Filtering data passed to the filer shader. See PxQueryFilterData PxBatchQueryPreFilterShader, PxBatchQueryPostFilterShader
[in]	userData	User can pass any value in this argument, usually to identify this particular query
[in]	cache	Cached hit shape (optional). Query is tested against cached shape first. If no hit is found the ray gets queried against the scene. Note: Filtering is not executed for a cached shape if supplied; instead, if a hit is found, it is assumed to be a blocking hit. Note: Using past touching hits as cache will produce incorrect behavior since the cached hit will always be treated as blocking.

Note: This query call writes to a list associated with the query object and is NOT thread safe (for performance reasons there is no lock and overlapping writes from different threads may result in undefined behavior).

virtual void PxBatchQuery::release ( )

pure virtual

Releases PxBatchQuery from PxScene.

See Also: PxScene, PxScene.createBatchQuery

virtual void PxBatchQuery::setRunOnSpu ( bool runOnSpu )

pure virtual

PS3 only. Enables or disables SPU execution for this query.

See Also: PxBatchQueryDesc

virtual void PxBatchQuery::setUserMemory ( const PxBatchQueryMemory & )

pure virtual

Sets new user memory pointers.

It is not possible to change the memory during query execute.

virtual void PxBatchQuery::sweep	(	const PxGeometry &	geometry,
		const PxTransform &	pose,
		const PxVec3 &	unitDir,
		const PxReal	distance,
		PxU16	maxTouchHits = `0`,
		PxHitFlags	hitFlags = `PxHitFlag::ePOSITION\|PxHitFlag::eNORMAL\|PxHitFlag::eDISTANCE`,
		const PxQueryFilterData &	filterData = `PxQueryFilterData()`,
		void *	userData = `NULL`,
		const PxQueryCache *	cache = `NULL`,
		const PxReal	inflation = `0.f`
	)

pure virtual

Performs a sweep test against objects in the scene, returns results in PxBatchQueryMemory::userSweepResultBuffer specified at PxBatchQuery creation time or via PxBatchQuery::setUserMemory call.

Note: Touching hits are not ordered.; If a shape from the scene is already overlapping with the query shape in its starting position, the hit is returned unless eASSUME_NO_INITIAL_OVERLAP was specified.

Parameters

[in]	geometry	Geometry of object to sweep (supported types are: box, sphere, capsule, convex).
[in]	pose	Pose of the sweep object.
[in]	unitDir	Normalized direction of the sweep.
[in]	distance	Sweep distance. Needs to be larger than 0. Will be clamped to PX_MAX_SWEEP_DISTANCE.
[in]	maxTouchHits	Maximum number of hits to record in the touch buffer for this query. Default=0 reports a single blocking hit. If maxTouchHits is set to 0 all hits are treated as blocking by default.
[in]	hitFlags	Specifies which properties per hit should be computed and returned in hit array and blocking hit.
[in]	filterData	Filtering data and simple logic. See PxQueryFilterData PxBatchQueryPreFilterShader, PxBatchQueryPostFilterShader
[in]	userData	User can pass any value in this argument, usually to identify this particular query
[in]	cache	Cached hit shape (optional). Query is tested against cached shape first. If no hit is found the ray gets queried against the scene. Note: Filtering is not executed for a cached shape if supplied; instead, if a hit is found, it is assumed to be a blocking hit. Note: Using past touching hits as cache will produce incorrect behavior since the cached hit will always be treated as blocking.
[in]	inflation	This parameter creates a skin around the swept geometry which increases its extents for sweeping. The sweep will register a hit as soon as the skin touches a shape, and will return the corresponding distance and normal. Note: ePRECISE_SWEEP doesn't support inflation. Therefore the sweep will be performed with zero inflation.

Note: This query call writes to a list associated with the query object and is NOT thread safe (for performance reasons there is no lock and overlapping writes from different threads may result in undefined behavior).
