502. BILD85: Multicolor Plots of Manifolds Which May
Penetrate Each Other

BILD is a program for the production of multicolored
plots of two-dimensional manifolds which may penetrate
each other in three-dimensional space. Each manifold
must be representable by mathematical expressions
leading to the form:
F(x,y,z) = 0
BILD is an extension of the usual three-dimensional
plotting programs which provide plots of only one
function described by the relation z-f(x,y) = 0.
Originally, BILD was designed for theoretical chemists
who wished to represent penetrating orbitals or
electron densities by means of attractive pictures, but
it can also be applied to other areas of science.
BILD is written in FORTRAN 77 and is essentially device
and computer independent. In order to implement the
program on a given machine, six machine-dependent
statements (calls to the plotter) have to be inserted
at predetermined positions in the interfacing user
subroutine.
