\class SoMFVec3b SoMFVec3b.h Inventor/fields/SoMFVec3b.h
\brief The SoMFVec3b class is a container for SbVec3b 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.
