Hello,
I'm trying to plot an isosurface in AppDesigner with:
load chestVolume
mask = 1800 <= V & V <= 3200;
p = patch(isosurface(mask));
p.FaceColor = 'red';
and it works fine.
Now I want to set the BackFaceLightning on 'unlit' and FaceLightning (on something, I don't know) so I can see where the inner surface and where he outer surface of the figure is. But when I set the properties nothing changes. Does anybody know why nothing changes and how I can fix it?

Okay, so the is a change. But the displayed object does not change, because there is no light() object, which could influence the lighting?

After you change properties, try with drawnow.
Wrong(FaceColor, FaceAlpha, EdgeColor, LineStyle are the only properties for patch.)

It is the ImageProcessing Toolbox that I use
