NAME

       plsurf3d - Plot shaded 3-d surface plot

SYNOPSIS

       plsurf3d(x, y, z, nx, ny, opt, clevel, nlevel)

DESCRIPTION

       Plots  a  three  dimensional  shaded  surface  plot within the environment set up by plw3d(3plplot).  The
       surface is defined by the two-dimensional array z[nx][ny], the point  z[i][j]  being  the  value  of  the
       function  at  (x[i], y[j]).  Note that the points in arrays x and y do not need to be equally spaced, but
       must be stored in ascending order. For further details see the PLplot documentation.

       Redacted form: plsurf3d(x, y, z, opt, clevel)

       This function is not used in any examples.

ARGUMENTS

       x (const PLFLT *, input)
              Pointer to set of x coordinate values at which the function is evaluated.

       y (const PLFLT *, input)
              Pointer to set of y coordinate values at which the function is evaluated.

       z (const PLFLT * const *, input)
              Pointer to a vectored two-dimensional array with set of function values.

       nx (PLINT, input)
              Number of x values at which function is evaluated.

       ny (PLINT, input)
              Number of y values at which function is evaluated.

       opt (PLINT, input)
              Determines the way in which the surface is represented. To specify more than one option  just  add
              the  options, e.g. FACETED + SURF_CONT opt=FACETED: Network of lines is drawn connecting points at
              which function is defined.  opt=BASE_CONT: A contour plot is drawn at  the  base  XY  plane  using
              parameters  nlevel  and clevel.  opt=SURF_CONT: A contour plot is drawn at the surface plane using
              parameters nlevel and clevel.  opt=DRAW_SIDES: draws a curtain between the base XY plane  and  the
              borders  of the plotted function.  opt=MAG_COLOR: the surface is colored according to the value of
              Z; if MAG_COLOR is not used, then the default the surface is colored according to the intensity of
              the  reflected  light  in  the  surface  from  a  light  source  whose  position  is   set   using
              pllightsource(3plplot).

       clevel (const PLFLT *, input)
              Pointer to the array that defines the contour level spacing.

       nlevel (PLINT, input)
              Number of elements in the clevel array.
