How can I assign a light source that only shines on one specific 3D object in a figure in MATLAB 7.9 (R2009b)?

I would like to plot 3D objects in a figure and apply a light source that only shines on one of the objects.

To assign a light source directly to a single 3D object, use different axes objects and assign the light source to the axes containing the object that should be lighted as shown in the following example:

close all

ax(1)=axes;

h = surf(peaks);

set(h,'FaceLighting','phong','FaceColor','interp',...

        'AmbientStrength',0.5)

light('Position',[1 0 0],'Style','infinite');

ax(2)=axes;

[X,Y,Z] = sphere(20);

surf(ax(2),3*X+10,3*Y+40,3*Z+5)

set(ax(2),'color','none', ...

      'Position',get(ax(1),'Position'), ...

      'Xlim',get(ax(1),'Xlim'), ...

      'Ylim',get(ax(1),'Ylim'), ...

      'Zlim',get(ax(1),'Zlim'), ...

      'XTick',[], ...

      'YTick',[], ...

      'ZTick',[] );

linkprop(ax,'view')
