topographical sculpture 3d model

"3D model of an intricate, multi-layered topographical structure. The base is a dark, granular matte surface. The layers are formed by a complex network of intertwined, organic lines, inspired by a detailed loofah pattern. These lines create deep, smooth depressions and raised contours, reminiscent of a luffa's internal structure or a neural network. Each layer's edge features a vibrant, iridescent rainbow gradient, shifting colors along its height, as if illuminated by colored LEDs. The overall aesthetic is abstract, sculptural, and highly detailed, with smooth transitions between layers and a subtle interplay of light and shadow emphasizing its depth. The central design is derived from the attached 2D sketch, extruded and layered to create volume."
