surfl
produces a shaded surface plot based on a combination of diffuse, specular and ambient lighting models. View the surfaces with a grayscale or similar colormap (such as gray
, copper
, bone
, pink
) and with interpolated shading.
surfl(Z)
, surfl(x,y,Z)
, surfl(Z,s)
, and surfl(x,y,Z,s)
are used the same way as surf(...)
, but accept an optional trailing argument s
. Argument s
, if specified, is a three-element vector s = [Sx Sy Sz]
that specifies the direction of the light source. s
can also be specified in spherical coordinates, s = [azimuth,elevation]
.
h = surfl(...)
returns a handle to a surface object.
The default value for s
is 45° counterclockwise from the current view direction. s
points from the object to the light source.
peaks
function, with a light source, is
[x,y] = meshgrid(-3:1/8:3);
z = peaks(x,y);
surfl(x,y,z);
shading interp
colormap(gray);
axis([-3 3 -3 3 -8 8])
