Inputs

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

In/Outputs
