502. BILD85: Multicolor Plots of Manifolds Which May
Penetrate Each Other
by Heinrich R. Karfunkel, Lehrstuhl fO(,ü)r Theoretische Chemie, Universität Tübingen, D-7400 Tübingen, Germany 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.
