  \class SoMFVec3i32 SoMFVec3i32.h Inventor/fields/SoMFVec3i32.h
  \brief The SoMFVec3i32 class is a container for SbVec3i32 vectors.
  \ingroup fields

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

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