plsurf3d: Plot shaded 3-d surface plot
Declaration
public void surf3d(Double[] x, Double[] y, Double[, ] z, Surf opt, Double[] clevel)Parameters
| Type | Name | Description |
|---|---|---|
| Double[] | x | A vector containing the x coordinates at which the function is evaluated. |
| Double[] | y | A vector containing the y coordinates at which the function is evaluated. |
| Double[,] | z | A matrix containing function values to plot. Should have dimensions of nx by ny. |
| Surf | opt | 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 surface is colored according to the intensity of the reflected light in the surface from a light source whose position is set using pllightsource. |
| Double[] | clevel | A vector containing the contour levels. |
Remarks
Plots a three-dimensional shaded surface plot within the environment set up by plw3d. The surface is defined by the two-dimensional matrix z[nx][ny], the point z[i][j] being the value of the function at (x[i],y[j]). Note that the points in vectors x and y do not need to be equally spaced, but must be stored in ascending order. For further details see .
