Create a massing model of a 1000-meter-tall residential tower with a sleek, modern architectural form, optimized for depth perception. Use strong, defined layering in the structure, with staggered or tiered sections to emphasize verticality and provide clear separation between different parts of the building. Incorporate recessed and protruding elements that create shadows and highlight varying depths in the design. Focus on clean lines and modular sections that accentuate the sense of scale and depth. The model should be all white to highlight these geometric forms and depth contrasts, set against an all-white background to further enhance depth perception. No site context or unnecessary details. --ar 9:16
