This class is a helper calling PxMeshQuery::findOverlapTriangleMesh or PxMeshQuery::findOverlapHeightField under the hood, while taking care of necessary memory management issues.
PxMeshQuery::findOverlapTriangleMesh and PxMeshQuery::findOverlapHeightField are the "raw" functions operating on user-provided fixed-size buffers. These functions abort with an error code in case of buffer overflow. PxMeshOverlapUtil is a convenient helper function checking this error code, and resizing buffers appropriately, until the desired call succeeds.
Returned triangle indices are stored within the class, and can be used with PxMeshQuery::getTriangle() to retrieve the triangle properties.
