Returns the control points and the quantity of control points in both u and v directions. 

Returns eOk if control point were successfully returned, or an appropriate error code in other case.

The control points will be allocated in the passed-in OdGePoint3d array. The column indexes are for the v direction, and row indexes are for the u direction. For example, if the surface has n control points in the u direction and m control points in the v direction, the array looks like [0,0], [0,1], ...[0,vCount-1], ..., [uCount-1,0], [uCount-1,1], ...[uCount-1,vCount-1].
