This is the approach I would take.
%preallocate
m = zeros(100,100,100);
m(1,21:80,21:80) = ones(60);
angle = 0.25:0.25:360;
for i = 1:1440
new = imrotate(squeeze(m(1,:,:)),i/4);
win1 = centerCropWindow2d(size(new),size(squeeze(m(1,:,:))));
m(i,:,:) = imcrop(new ,win1);
end
figure
isosurface(m)
view(0,90)
