Description |
|---|---|---|---|
|
hrPrev |
|
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipPointSet |
|
Source point set (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL; The elements of this container are the individual points.) | |
|
ipConvexHull |
|
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 |
false |
Selects the sorting direction of the hull points, assuming cartesian coordinates. |
