PV-WAVE BASIC FUNCTIONS DEMONSTRATION

-----------------------------------------------------------------
SECTION 3.   (3-D DATA DISPLAY)
-----------------------------------------------------------------
In this section of the demo, a "Binary Unformatted" data
file is used containing a 60x60 grid of floating point
Z values.

The PV-WAVE code to read this data file into a PV-WAVE
variable is as follows :

   ;*************************************************************
   surface_dat = Fltarr(60, 60)
   Openr, 1, !!Data_Dir + 'bsc_surf.dat', /Xdr
   Readu, 1, surface_dat
   Close, 1
   ;*************************************************************

The following PV-WAVE command can be used to display this data as
a mesh surface with hidden lines removed :

   ;*************************************************************
   Surface, surface_dat, Ax=30.0, Az=30.0, Color=127, Bottom=100
   ;*************************************************************
