Using
Rotate 3D
only rotates the 3D plot, not the colorbar. h e function
surfc
combines both a surface and a 2D contour plot in one graph.
surfc(XI,YI,ZI)
h e function
surfl
can be used to illustrate an advanced application for 3D
visualization, generating a 3D colored surface with interpolated shading
and lighting. h e axis labeling, ticks, and background can be turned of by
typing
axis off
. In addition, black 3D contours can be added to the surface,
as above. h e grid resolution is increased prior to data plotting in order to
obtain smooth surfaces (Fig. 7.7).
