3D Model: Ultra-detailed, Architecturally Accurate 3D Model Of The Oriental Pearl Tower (Dongfang Mingzhu), Shanghai — Scale In Meters, High-poly Main Geometry With Game-ready LODs And Clean Topology. Focus On Structural Accuracy, Correct Sphere Count And Principal Diameters, Realistic Material Separation, And Production-ready UVs. Geometry & Proportions: - Total Height: 468 M (use Meters As Units). - Eleven Spheres Of Varying Sizes Arranged Vertically Along A Central Shaft — Include The Two Largest Primary Spheres And Smaller Intermediary Spheres. - Two Largest Spheres: Lower Main Sphere Diameter ≈ 50 M, Upper Main Sphere Diameter ≈ 45 M. Include The Smallest Topmost Sphere ≈ 14 M Diameter. - Central Vertical Shaft: Slender Reinforced Concrete Cylinder (smooth, Slightly Tapered), Connect Spheres Via Integrated Steel Framework. - Three Main Diagonal Support Columns / Slanting Stanchions Rising From Base To Mid-level (base-to-sphere Connection) — Model Each Support As Hollow Structural Stee
