  \class SoMFVec4f SoMFVec4f.h Inventor/fields/SoMFVec4f.h
  \brief The SoMFVec4f class is a container for SbVec4f vectors.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store an array of vectors with four elements.

  This field supports application data sharing through a
  setValuesPointer() method. See SoMField documentation for
  information on how to use this function.
