How to display a 3d array in 3d using texture mapping

Sir,

I am able to display 2D array as a Solid rectangle. But How to display 3d array as solid CUBE in 3d, I got vol3d.m file from the net but I am not aware of input parameter 'varargin' , whether 'a' can be input.

k=50; a = zeros(k,k,k) % Preallocate matrix for m = 1:k for n = 1:k for r = 1:k if( ( abs(m-24)+abs(n-24)+ abs(r-24)) < 24) a(m,n) = 255; end

    end
end

How to display a as cube using texture mapping ?

like 2d function f1() k=50; a = zeros(k,k) % Preallocate matrix for m = 1:k for n = 1:k if( ( abs(m-24)+abs(n-24)) < 24) a(m,n) = 255; end

    end
end

imshow(a);

return

end
