\class SoMFVec3f SoMFVec3f.h Inventor/fields/SoMFVec3f.h
\brief The SoMFVec3f class is a container for SbVec3f 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.
