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.) |
