\class SoMFVec2s SoMFVec2s.h Inventor/fields/SoMFVec2s.h
\brief The SoMFVec2s class is a container for SbVec2s vectors.
\ingroup fields
This field is used where nodes, engines or other field containers
needs to store an array of vectors with two elements.
This field supports application data sharing through a
setValuesPointer() method. See SoMField documentation for
information on how to use this function.
