Detailed Description

utility functions for use with PxScene, related to scene queries.

Some of these functions have been deprecated (removed) in PhysX 3.4. We re-implement them here for easy migration from 3.3 to 3.4.

static bool PxSceneQueryExt::overlapAny ( const PxScene &  scene,
const PxGeometry &  geometry,
const PxTransform &  pose,
PxOverlapHit &  hit,
const PxSceneQueryFilterData &  filterData = PxSceneQueryFilterData(),
PxSceneQueryFilterCallback *  filterCall = NULL,
PX_DEPRECATED PxClientID  queryClient = PX_DEFAULT_CLIENT 
) [static]

Test returning, for a given geometry, any overlapping object in the scene.

Note:
Filtering: Overlap tests do not distinguish between touching and blocking hit types. Both trigger a hit.

PxHitFlag::eMESH_MULTIPLE and PxHitFlag::eMESH_BOTH_SIDES have no effect in this case

Parameters:
[in] scene The scene
[in] geometry Geometry of object to check for overlap (supported types are: box, sphere, capsule, convex).
[in] pose Pose of the object.
[out] hit Pointer to store the overlapping object to.
[in] filterData Filtering data and simple logic.
[in] filterCall Custom filtering logic (optional). Only used if the corresponding PxHitFlag flags are set. If NULL, all hits are assumed to overlap.
[in] queryClient ID of the client doing the query
Returns:
True if an overlap was found.
Deprecated:
PxActorClientBehaviorFlag feature has been deprecated in PhysX version 3.4

PX_DEPRECATED PxClientID  queryClient = PX_DEFAULT_CLIENT 
) [static]

Test overlap between a geometry and objects in the scene.

Note:
Filtering: Overlap tests do not distinguish between touching and blocking hit types. Both get written to the hit buffer.

PxHitFlag::eMESH_MULTIPLE and PxHitFlag::eMESH_BOTH_SIDES have no effect in this case

Parameters:
[in] scene The scene
[in] geometry Geometry of object to check for overlap (supported types are: box, sphere, capsule, convex).
[in] pose Pose of the object.
[out] hitBuffer Buffer to store the overlapping objects to. If the buffer overflows, an arbitrary subset of overlapping objects is stored (typically the query should be restarted with a larger buffer).
[in] hitBufferSize Size of the hit buffer.
[in] filterData Filtering data and simple logic.
[in] filterCall Custom filtering logic (optional). Only used if the corresponding PxHitFlag flags are set. If NULL, all hits are assumed to overlap.
[in] queryClient ID of the client doing the query
Returns:
Number of hits in the buffer, or -1 if the buffer overflowed.

PxSceneQueryFilterCallback *  filterCall = NULL,
const PxSceneQueryCache *  cache = NULL,
PX_DEPRECATED PxClientID  queryClient = PX_DEFAULT_CLIENT 
) [static]

Raycast returning any blocking hit, not necessarily the closest.

Returns whether any rigid actor is hit along the ray.

Note:
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] scene The scene
[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.
[out] hit Raycast hit information.
[in] filterData Filtering data and simple logic.
[in] filterCall Custom filtering logic (optional). Only used if the corresponding PxHitFlag flags are set. If NULL, all hits are assumed to be blocking.
[in] cache Cached hit shape (optional). Ray 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] queryClient ID of the client doing the query
Returns:
True if a blocking hit was found.

Raycast returning multiple results.

Find all rigid actors that get hit along the ray. Each result contains data as specified by the outputFlags field.

Note:

[in] distance Length of the ray. Needs to be larger than 0.

[in] hitBufferSize Size of the hit buffer.
[out] blockingHit True if a blocking hit was found. If found, it is the last in the buffer, preceded by any touching hits which are closer. Otherwise the touching hits are listed.
[in] filterData Filtering data and simple logic.
[in] filterCall Custom filtering logic (optional). Only used if the corresponding PxHitFlag flags are set. If NULL, all hits are assumed to be touching.
[in] cache Cached hit shape (optional). Ray is tested against cached shape first then against the scene.
