setstereo

Create a rotatable stereoscopic view of 3D data with two side-by-side subplots.

SETSTEREO yokes the camera positions in two axes to provide a rotatable stereoscopic view of points and surfaces plotted in 3 dimensions. The relationship between the axes is maintained with a callback, UPDATESTEREO.

For example, to plot a stereoscopic view of the Matlab logo surface:

% Create the surface
L = 160*membrane(1,100);

% Create a figure with two identical subplots
figure
ax1 = subplot(1,2,1);
s1 = surface(L);
view(3)
axis equal vis3d off
ax2 = subplot(1,2,2);
s2 = surface(L);
view(3)
axis equal vis3d off
set([s1 s2],'EdgeColor','none');
set([ax1 ax2],'clipping','off')

% Lock the position of the cameras to maintain a fixed separation; positive separation for divergent viewing and negative for crossed.
setstereo(ax1,ax2,.075)
rotate3d on

Now you can manipulate either axis while viewing the result in stereo by diverging your eyes or using a handheld stereoscope.
