NAME
       plw3d - Set up window for 3-d plotting

SYNOPSIS
       plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt,
       az)

DESCRIPTION
       Sets up a window for a three-dimensional surface plot within the
       currently defined two-dimensional window.  The enclosing box for the
       surface plot defined by xmin, xmax, ymin, ymax, zmin and zmax in user-
       coordinate space is mapped into a box of world coordinate size basex by
       basey by height so that xmin maps to -basex/2, xmax maps to basex/2,
       ymin maps to -basey/2, ymax maps to basey/2, zmin maps to 0 and zmax
       maps to height.  The resulting world-coordinate box is then viewed by
       an observer at altitude alt and azimuth az.  This routine must be
       called before plbox3(3) or plot3d(3).  For a more complete description
       of three-dimensional plotting see the PLplot documentation.

       Redacted form: plw3d(basex, basey, height, xmin, xmax, ymin, ymax,
       zmin, zmax, alt, az)

       This function is examples 8,11,18,21.

ARGUMENTS
       basex (PLFLT, input)
              The x coordinate size of the world-coordinate box.

       basey (PLFLT, input)
              The y coordinate size of the world-coordinate box.

       height (PLFLT, input)
              The z coordinate size of the world-coordinate box.

       xmin (PLFLT, input)
              The minimum user x coordinate value.

       xmax (PLFLT, input)
              The maximum user x coordinate value.

       ymin (PLFLT, input)
              The minimum user y coordinate value.

       ymax (PLFLT, input)
              The maximum user y coordinate value.

       zmin (PLFLT, input)
              The minimum user z coordinate value.

       zmax (PLFLT, input)
              The maximum user z coordinate value.

       alt (PLFLT, input)
              The viewing altitude in degrees above the XY plane.

       az (PLFLT, input)
              The viewing azimuth in degrees.  When az=0, the observer is
              looking face onto the ZX plane, and as az is increased, the
              observer moves clockwise around the box when viewed from above
              the XY plane.
