Name

Type

Description

ipSrcPoints

ITcVnContainer

Source points (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_LREAL)

ipDestPoints

Reference To ITcVnContainer

Returns the transformed points (same type ID as ipSrcPoints; Non-zero interface pointers are reused.)

hrPrev
