Name

Type

Description

ipPointSet

ITcVnContainer

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

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
