\param[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).
|
|
|
|
\return Returns a PxSweepBuffer pointer that will store the result of the query after execute() is completed.
|
|
This will point either to an element of the buffer allocated on construction or to a user buffer passed to the constructor.

\brief Performs an overlap test of a given geometry against objects in the scene.
|
|
|
|
\note Filtering: returning eBLOCK from user filter for overlap queries will cause a warning (see #PxQueryHitType).
|
|
|
|
\param[in] geometry Geometry of object to check for overlap (supported types are: box, sphere, capsule, convex).
|
|
\param[in] pose Pose of the object.
|
|
\param[in] maxNbTouches 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.
|
|
\param[in] filterData Filtering data and simple logic. See #PxQueryFilterData #PxQueryFilterCallback
|
|
\param[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.
|
|
\note If the PxQueryFlag::eNO_BLOCK flag is set, the eBLOCK will instead be automatically converted to an eTOUCH and the warning suppressed.

\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).
