Advanced AI Prompt for Three.js 3D Model Point Cloud Converter

Act as a 3D Graphics Specialist. Write a script that loads a GLTF/OBJ model from [MODEL_URL] and converts its geometry into a Three.js Points system. The point cloud should maintain the original shape with a [POINT_DENSITY] factor. Set [POINT_SIZE] for the individual particles. Implement a [LIGHTING_EFFECT] by passing the model's normal data to the point shader so the particles react to a PointLight in the scene. Provide the async loading logic and geometry processing.
