Create a massing model of a 1000-meter-tall residential tower with a sleek, modern architectural form. The model should emphasize clean, functional design without site context or decorative elements. Focus on the verticality and proportions of the tower, with subtle references to traditional Chinese forms like pagoda tiering, but keeping the overall design contemporary and feasible. The tower should have structured divisions for residential use, using elegant and minimalistic geometry. The model should be all white on an all-white background. --ar 9:16
