Save 3D figure with rotational view

Question

Oscar Hartogensis 2011-3-10

Is it possible to save a Matlab 3D plot to an external image format (not *.fig) where the viewer can control the rotation of the image?

On the web you see these examples all the time (using flash or java?); eg: http://www.yofla.com/flash/3d-rotate/flexi/

I am using Matlab 2009a

Perhaps save it as VRML.

It appears there is a coordinate adjustment that would have to be made for VRML; see this previous discussion

Thanks Walter for this suggestion. I tried it out, but unfortunately it did not work for me. This is what I did:

[x,y] = meshgrid(-2:.2:2,-1:.15:1);

z = x .* exp(-x.^2 - y.^2);

[u,v,w] = surfnorm(x,y,z);

quiver3(x,y,z,u,v,w);

set(gca,'xtick',[],'ytick',[],'ztick',[])

vrml(gca,'test')

To view the output I installed the following browser plugin:
