Rotation of orthogonal projection

I have a depth image (x,y,z = pixel value). I project the image into top and side views:

for i = 1:rows
  for j = 1:cols
   if front(i,j)~=0
    side(i, front(i,j)) = j;
    top(front(i,j), j) = i;
   end
  end
end

If I use imrotate() to rotate the front view, how can I process the side and top view in order to get the rotation projection? I know it's easy to rotate first then project into side and top views but I want to know how to do rotation of the two views given angle and center of rotation.
