C HIDDEN SURFACE, CONTOURING AND SHADING OPTIONS, AS WELL AS SEVERAL
C MULTICOLOR TECHNIQUES. THE SURFACE EMPLOYED IS A RATHER SIMPLE
C APPROXIMATION TO THE TETRAHEDRAL BONDING FUNCTIONS, AND THEREFORE
C IS ONE WHICH HAS LARGE LOBES IN THE TETRAHEDRAL DIRECTIONS. THE
C VARIABLE L SELECTS ONE OF THE FOLLOWING OPTIONS.
C L=1 ORDINARY PERSPECTIVE AND CONTOURS
C L=2 CHECKERBOARD OF LATITUDE AND LONGITUDE
C L=3 CONTOUR BANDS

C VIEW OF FUNCTIONS DEFINED OVER A SPHERE. A GRID OF SPINES IS
C PLACED ON THE FIGURE AS AN AID TO LOCATING CONTOURS; EACH SPINE
C IS ROUNDED UP TO THE NEXT TENTH.
C [27-MAY-74]
SUBROUTINE DEM21
C [DEM21]
C DEMONSTRATION FOR THE PROGRAM PLTSV, WHICH SHOWS A PERSPECTIVE
C VIEW OF FUNCTIONS DEFINED OVER A SPHERE.
C [27-MAY-74]
SUBROUTINE DEM22
C [DEM22]
C PLANETARY COPPER MINE
C DEMONSTRATION FOR THE PROGRAM PLTSV, WHICH SHOWS A PERSPECTIVE
C VIEW OF FUNCTIONS DEFINED OVER A SPHERE. QUANTIFICATION IS USED
C TO INDICATE THE VARIOUS RADIAL CONTOUR LEVELS OF THE FUNCTION.
C [02-JUN-74]
SUBROUTINE DEM23
C [DEM23]
C CALCULATION OF THE TILT OF THE ELEMENTARY RECTANGLES
C AS A FUNCTION OF THETA AND PHI FOR USE IN CHOOSING
C THE DIAGONAL SEQUENCE TO BE FOLLOWED IN THE SPHERICAL
C SEQUENCE ROUTINES.
C [28-MAY-74]
SUBROUTINE DEM24
C [DEM24]
C [03-JUN-74]
SUBROUTINE DEM25
C [DEM25]
C [29-MAY-74]
C [DEM26]
C DEMONSTRATION OF TWO PARTICLES IN A COULOMB WELL
C [18-MAY-74]
C [DEM27]
C DEMONSTRATION OF TWO PARTICLES IN AN EXPONENTIAL WELL
C [18-MAY-74]
C [DEM28]
C DEMONSTRATION OF THE POTENTIAL FELT BY TWO PARTICLES IN A GAUSSIAN
C WELL. THE SURFACE ARISES FROM THE USE OF HYPERSPHERICAL HARMONICS
C IN QUANTUM MECHANICS. HERE IT IS USED TO ILLUSTRATE A TECHNIQUE
C OF SKETCHING OUT A COARSE SURFACE INTO WHICH IS INSERTED A DENSER
C REGION OF SPECIAL INTEREST. THE DETAIL WHICH IS DESIRED IS THE
C SHAPE OF THE BOTTOM OF THE TROUGHS CROSSING AT THE CENTER OF THE
C DRAWING.
C [06-OCT-74]
C [DEM29]
C DEMONSTRATION OF TWO PARTICLES IN A GAUSSIAN WELL
C [14-NOV-74]
C [DEM30]
C DEMONSTRATION FOR THE REPRESENTATION OF A FUNCTION OF A COMPLEX
C VARIABLE. THE COMPLEX CONTOURING PROGRAM PLTKC AUTOMATICALLY
C CONTOURS BOTH THE MODULUS AND THE ARGUMENT OF A COMPLEX FUNCTION,
C WHICH IT RECEIVES IN THE FORM OF A COMPLEX ARRAY.
C [26-MAY-75]
C [DEM31]
C DEMONSTRATION FOR THE REPRESENTATION OF A FUNCTION OF A COMPLEX
C VARIABLE. THE MODULUS OF THE FUNCTION CAN BE SHOWN AS A SURFACE IN
C THREE DIMENSIONS, BUT THE PHASE IS LOST IN THE PROCESS. BY SHOWING
C CONTOURS OF CONSTANT PHASE THE LOST INFORMATION IS REGAINED, BUT
C IT IS HARD TO SHOW CONTOURS ON A SURFACE ALREADY DENSELY POPULATED
C BY LINEAR ARCS. BY SHOWING REGIONS OF DIFFERENT PHASE IN DIFFERENT
C COLORS THE INFORMATION IS PRESENTED IN A READILY PERCEIVABLE FORM.
C [26-MAY-75]
C [DEM32]
C DEMONSTRATION FOR THE INCLINED VIEW PROGRAM PLTIV. THE SURFACE
C REPRESENTED IS THE SAME ONE USED IN DEM30 AND DEM31, WHICH IS THE
C ABSOLUTE VALUE OF A FUNCTION OF A COMPLEX VARIABLE WITH FIVE POLES
C LOCATED AT THE VERTICES OF A REGULAR HEXAGON. TWO OPTIONS SHOW
C SHOW DIFFERENT STAGES OR ROTATION ABOUT A VERTICAL AXIS (L=1) OR
C DIFFERENT DEGREES OF TILT ABOUT A HORIZONTAL AXIS (L=2).
C [30-MAY-75]
C [DEM33]
C DEMONSTRATION OF A COLOR COMPOSITE
C [18-DEC-74]
C [DEM34]
C DEMONSTRATION FOR THE ORTHOGRAPHIC RELIEF PROGRAM. THE SURFACE
C SHOWN IS RELATED TO THE SURFACE OF DEM30, DEM31, AND DEM33, BY THE
C SUBTRACTION OF THE VARIABLE Z. THE OBJECTIVE IS TO LOCATE POINTS
C WHERE THAT SURFACE EQUALS Z; ORTHOGRAPHIC RELIEF WILL SOMETIMES
C AID TO DISTINGUISH DEPRESSIONS IN A SURFACE FROM PROTRUBERANCES.
C OPTION L ALLOWS GENERATION OF AN ORTHOGRAPHIC RELIEF (L=2) OR AN
C ORDINARY CONTOUR (L=1). IF THESE ARE DONE IN TWO DIFFERENT COLORS
C AND SUPERPOSED, THEY WILL SOMETIMES ENHANCE ONE ANOTHER.
C [08-JUN-75]
C [DEM35]
C DEMONSTRATION OF BIRDSEYE VIEW
C [18-DEC-74]
C [DEM38]
C DEMONSTRATION PROGRAM FOR PLTRI. THE PRINCIPAL POINT OF INTEREST
C IN THIS DEMONSTRATION IS THE FACT THAT VIRTUALLY ANY COORDINATE
C SYSTEM MAY BE USED FOR PLOTTING A GRAPH, AND THAT THE AXIS DRAWING
C OPTION WILL FAITHFULLY DRAW THE COORDINATE AXES OF THE SYSTEM IN
C USE. BY SELECTING OPTIONS L=1,2,3,4,5, THE FIVE COORDINATE SYSTEMS
C CARTESIAN, POLAR, ELLIPTIC, SPHERICAL POLAR, OR TRIANGULAR, MAY BE
C TESTED.
