topographic 3d model

"Create a 3D topographic model from the attached image. Interpret the blue areas as the highest and outermost surface layer of an organic, interconnected network. All red and reddish-toned areas within the blue network represent varying depths and cavities, with darker reds indicating deeper areas. The model should have a distinct multi-layered, carved-out appearance, mimicking a detailed topographical map or a luffa's internal structure. Maintain smooth transitions between layers and emphasize the volumetric depth suggested by the color gradients, creating a sculptural, intricate object with clear internal cavities. The overall thickness of the resulting 3D object should be approximately 5 centimeters."
