A problem with 3d visualization on MATLAB

[Luckybuilding]

Hi,
I wanna create a 3d surface for my data representing an object.

I have obtained the data for borders of each slice.

However, I can't create any surface!


Used code is:

for a=1:length(D(1,1,:))
    X=D(:,:,a);
    BW = im2bw(X,mp,0.75);
    CC = bwconncomp(BW);
    for b=1:CC.NumObjects
        clear TMP;
        TMP=cell2mat(CC.PixelIdxList(b));
        if isempty(find(TMP==fix(p_f)))
            BW(CC.PixelIdxList{b}) = 0;
        end
    end
    O(:,:,a)=imfill(BW,'holes');
end
figure;
phandles = contourslice(O,[],[],[20:57],1);
view(3); axis tight
set(phandles,'LineWidth',2)

Os = smooth3(O);
hiso = patch(isosurface(Os,1),...
    'FaceColor',[1,.75,.65],...
    'EdgeColor','none');

The output image is shown below:





How can I create the surface out of these borders?


Thanks

I believe you need a more sophisticated rendering engine. It will connect neighboring data points to create a surface.

It will have features such as shading, hidden surface hiding, etc.

Thanks for your reply.
However, can you be specific and suggest an engine for this?

If MATLAB has a 3D rendering module available somewhere, then you're all set.

Otherwise you'll need to use a different programming package.

List of various 3D software rendering engines:

Also look into modules such as OpenGL, TBGL, and DirectX. These go with certain programming languages.

Or for a simple surface drawing method...
Draw vertical lines between a data point on one level, to a related data point on another level. Do this several times and it won't be too hard to visualize a solid object.
