PLOT3D(3plplot) PLplot API PLOT3D(3plplot) NAME
plot3d - Plot 3-d surface plot SYNOPSIS
plot3d(x, y, z, nx, ny, opt, side) DESCRIPTION
Plots a three dimensional 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. The parameter opt controls the way in which the surface is displayed. For fur- ther details see the PLplot documentation. The only difference between plmesh(3plplot) and plot3d(3plplot) is that plmesh(3plplot) draws the bottom side of the surface, while plot3d(3plplot) only draws the surface as viewed from the top. Redacted form: plot3d(x, y, z, opt, side) This function is used in examples 11,21. 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: 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. side (PLBOOL, input) Flag to indicate whether or not ``sides'' should be draw on the figure. If side is true sides are drawn, otherwise no sides are drawn. AUTHORS

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-dimen- sional 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 (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. 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.
