Sets a point equal to the ray's origin.
[Visual Basic .NET] Public Sub QueryOrigin ( _ ByVal vectorOrigin As IPoint _ )
[C#] public void QueryOrigin ( IPoint vectorOrigin );
[C++]
HRESULT QueryOrigin(
IPoint* vectorOrigin
);
[C++]
Parameters vectorOrigin
vectorOrigin is a parameter of type IPoint
Returns the Origin of the Ray into the input Point.
Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.
