single hit cache for scene queries.
<p>
If a cache object is supplied to a scene query, the cached actor/shape pair is checked for intersection first. <dl class="note" compact><dt><b>Note:</b></dt><dd>Filters are not executed for the cached shape. <p>
If intersection is found, the hit is treated as blocking. <p>
Typically actor and shape from the last <a class="el" href="structPxHitCallback.html#63b2851eaf99b190fc468e00e8d1e55d" title="Holds the closest blocking hit result for the query. Invalid if hasBlock is false...">PxHitCallback.block</a> query result is used as a cached actor/shape pair. <p>
Using past touching hits as cache will produce incorrect behavior since the cached hit will always be treated as blocking. <p>
Cache is only used if no touch buffer was provided, for single nearest blocking hit queries and queries using eANY_HIT flag. <p>
if non-zero touch buffer was provided, cache will be ignored<p>
It is the user's responsibility to ensure that the shape and actor are valid, so care must be taken when deleting shapes to invalidate cached references.</dd></dl>
The faceIndex field is an additional hint for a mesh or height field which is not currently used.<p>
