Package plwf (in plwf.i) -
Index of documented functions or symbols:
DOCUMENT lightwf, cmax Sets the cmax= parameter interactively, assuming the current 3D display list contains the result of a previous plwf call. This changes the color of the brightest surface in the picture. The darkest surface color can be controlled using the ambient= keyword to light3.
DOCUMENT plwf, z or plwf, z, y,x plots a 3-D wire frame of the given Z array, which must have the same dimensions as the mesh (X, Y). If X and Y are not given, they default to the first and second indices of Z, respectively. The drawing order of the zones is determined by a simple "painter's algorithm", which works fairly well if the mesh is reasonably near rectilinear, but can fail even then if the viewpoint is chosen to produce extreme fisheye perspective effects. Look at the resulting plot carefully to be sure the algorithm has correctly rendered the model in each case. KEYWORDS: fill -- optional colors to use (default is to make zones have background color), same dimension options as for z argument to plf function shade -- set non-zero to compute shading from current 3D lighting sources edges -- default is 1 (draw edges), but if you provide fill colors, you may set to 0 to supress the edges ecolor, ewidth -- color and width of edges cull -- default is 1 (cull back surfaces), but if you want to see the "underside" of the model, set to 0 scale -- by default, Z is scaled to "reasonable" maximum and minimum values related to the scale of (X,Y). This keyword alters the default scaling factor, in the sense that scale=2.0 will produce twice the Z-relief of the default scale=1.0. cmax -- the ambient= keyword in light3 can be used to control how dark the darkest surface is; use this to control how light the lightest surface is the lightwf routine can change this parameter interactively
