Hi, I would like to ask for a projection issue in isosurface command.
More precisely, I hope to project a 3D object to the 2D plane, which can be found in the following figure.
I have made a short code to produce a simple geometric object. Hope someone could help me to visualize the object as the figure do. Thanks!

% mesh:
xx=1:20;
yy=1:20;
zz=1:20;
[X,Y,Z] = meshgrid(xx,yy,zz);
%init the test volume data test
test = zeros(size(X));
%small cube at lower
test(5:8,5:8,5:7)=50;
%large cube at higher
test(7:11,7:11,8:11)=60;
%isosurface
p= patch(isosurface(X,Y,Z,test,1));
isonormals(X,Y,Z,test,p)
set(p,'FaceColor','red','EdgeColor','none');
daspect([1 1 1])
view(3); axis([1,20,1,20,1,20])

When we run this code, we don't get the results shown above!!

The sample code does not attempt to work with the teapot. It works with some artificial data which is two cubes stuck together.
