 Inputs
| Name | Type | Description | 
|---|---|---|
| ipPointSet | Source point set (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL; The elements of this container are the individual points.) | |
| ipConvexHull | Reference To ITcVnContainer | Returns a container which is filled with the sorted convex hull points (same type ID as ipPointSet; Non-zero interface pointers are reused.) | 
| bClockwise | BOOL | Selects the sorting direction of the hull points, assuming cartesian coordinates. | 
| hrPrev | HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
