Sculpture exists in the world we ourselves occupy. However sculptors have
a variety of formats to follow. There are three types of spatial
experiences: relief, in-the-round, and installation. Sculpture in relief
is only three-dimensional with real hills and valleys on one side; the
back is flat. Relief sculpture is akin to a “bumpy” framed painting.
Sculpture in-the-round is self-supporting, standing on its own “feet.” It
must employ ponderation, have an adequate balance of weight to prevent
toppling. Sculpture in-the-round must be finished on all sides so the
viewer can walk around it. Installation sculpture is also free standing
but the viewer can actually enter into it and totally experience it.
