SURFMODL is an incredible modeling system which produces realistic
three-dimensional images on a graphics display. Surfmodl works with object
defined by a wire frame. The wire frame defines a surface consisting of
many polygons. These surfaces can be displayed with the hidden lines
removed and viewed from any angle. Light sources can be defined and the
image will reflect the appropriate shades depending upon the intensity of
the light, distance from it and the angle of incidence of the light to the
surface.
The Surfmodl package includes the Preproc program which will allow the
user to quickly generate Surfmodl data files consisting of surfaces of
revolution, extrusion and simple planes. data files to be easily combined.
Preproc makes certain classes of objects very easy to create. The Surfmodl
data file FAN. was created by running Preproc with the input file FAN.IN.
Complete documentation on the use of Preproc can be found in SURFMODL.DOC.
Upon invocation, Surfmodl will bring up the main menu from which the
object may be plotted as a wire frame, with or without hidden lines, or
using surface modelling. If an input filename was not specified, it must
be read in by selecting option 0 followed by option 1. Menu options are
selected by pressing the number corresponding to the option desired, or
pressing the function key of the same number. Option 0 always returns to
the previous menu or, in the case of the main menu, exits the program.
Surfmodl was written in Turbo Pascal and the source is included on the
third disk. The recompilation process is involved as there
are separate sequences that must take place depending on the type of
machine and display adapter for which Surfmodl is being recompiled.
Complete recompilation instructions are given in SURFMODL.DOC. Some
versions will require the Borland's Turbo Graphix Toolbox and a program by
Jim Pelley called Sgraph which contain graphics procedures necessary for
recompilation.
