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(3plplot) or plot3d(3plplot).  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)

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.
