3D Model: "Generate A Highly Realistic 3D Model Of A Large Concrete Gravity Dam Located In A Mountainous Area. The Dam Should Include Visible Structural Elements Like The Spillway, Intake Towers, Service Bridge, And Downstream River Flow. Add Water In The Reservoir Behind The Dam And Rocky Terrain With Vegetation Around It. Use Realistic Lighting And Textures To Make The Concrete Look Weathered And The Water Reflective. The Scene Should Look Like A Real-world Hydroelectric Facility Viewed From A Drone Perspective.
