NAME

       plmeshc - Magnitude colored plot surface mesh with contour.

SYNOPSIS

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

DESCRIPTION

       Identical  to  plmesh  but  with extra functionalities: the surface mesh can be colored accordingly to the current z value being plotted, a
       contour plot can be drawn at the base XY plane, and a curtain can be drawn between the plotted function border and the base XY plane.

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

       This function is used in example 11.

ARGUMENTS

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

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

       z (PLFLT **, 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.  DRAW_LINEXY  +
	      MAG_COLOR  opt=DRAW_LINEX:  Lines  are  drawn  showing z as a function of x for each value of y[j].  opt=DRAW_LINEY: Lines are drawn
	      showing z as a function of y for each value of x[i].  opt=DRAW_LINEXY: Network of lines is drawn connecting points at which function
	      is defined.  opt=MAG_COLOR: Each line in the mesh is colored according to the z value being plotted. The color is used from the cur-
	      rent colormap 1.	opt=BASE_CONT: A contour plot is drawn at the base XY plane using parameters nlevel and  clevel.   opt=DRAW_SIDES:
	      draws a curtain between the base XY plane and the borders of the plotted function.

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

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

NAME

       plfsurf3d - Plot shaded 3-d surface plot

SYNOPSIS

       plsurf3d(x, y, zops, zp, 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 data contained
       in the 2D  PLFLT ** matrix or the PLfGrid2 structure zp. How the data in  zp is rendered is determined by the  zops parameter.  zops  is  a
       pointer	to  a  function  that  reads the data out of the grid structure. The following functions in PLplot core will return an appropriate
       function pointer:  plf2ops_c() (use when  zp is of type	PLFLT **), plf2ops_grid_c() (use when  zp is a pointer	to  a  row-major  PLfGrid2
       structure),   plf2ops_grid_row_major()  (same  as  plf2ops_grid_c()?) and  plf2ops_grid_col_major() (use when zp is a pointer to a  column-
       major PLfGrid2 structure).  nx, nyoptclevel and nlevel are the same as in for example plsurf3d(3plplot).

       Redacted form? plfsurf3d(x, y, zops, zp, opt, clevel)

       This function is used in example 8.

ARGUMENTS

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

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

       zops (void (*) (?), input)
	      Pointer to a function for processing the data contained in zp.

       zp (PLFLT ** or PLfGrid2 *, input)
	      Pointer to the data to be plotted, either as a vectored  two-dimensional array with set of function values, or  as  PLfGrid2  struc-
	      ture.

       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  pllight-
	      source(3plplot).

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

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