class PxMeshOverlapUtil
Utility class to find mesh triangles touched by a specified geometry object.
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.

- Parameters
geom – [in] The geometry object to test for mesh triangle overlaps. Supported geometries are PxSphereGeometry, PxCapsuleGeometry and PxBoxGeometry
geomPose – [in] Pose of the geometry object
meshGeom – [in] The triangle mesh geometry to check overlap against
meshPose – [in] Pose of the triangle mesh
- Returns
Number of overlaps found. Triangle indices can then be accessed through the getResults() function.

PxU32 findOverlap(const PxGeometry &geom, const PxTransform &geomPose, const PxHeightFieldGeometry &hfGeom, const PxTransform &hfPose)
Find the height field triangles which touch the specified geometry object.

- Parameters
geom – [in] The geometry object to test for height field overlaps. Supported geometries are PxSphereGeometry, PxCapsuleGeometry and PxBoxGeometry. The sphere and capsule queries are currently conservative estimates.
geomPose – [in] Pose of the geometry object
hfGeom – [in] The height field geometry to check overlap against
hfPose – [in] Pose of the height field
- Returns
Number of overlaps found. Triangle indices can then be accessed through the getResults() function.
