abstract = {A new display scheme is presented in which three-dimensional
objects are represented with a much higher degree of user control
of the line-drawing format than those in conventional schemes. In
this scheme, the attribute of a line is determined not at the time
of definition but after the viewing transformation has been
applied, taking the shielding environment of the line into
consideration. The essential difference between our scheme and
conventional hidden-line removal/indication lies in the treatment
of the shielding environment. In conventional hidden-line
removal/indication, only the visible/invisible information is
available for the selection of the attribute of a line. In our
scheme, the entire set of surfaces that hide a line can be used to
determine the attribute of the line. A much higher degree of
freedom in generating pictures is achieved owing to the treatment
of the shielding environment. We also describe a system called
GRIP, which implements the new scheme.},
