Code Sample

// Neural Network Visualization Class
class NeuralNetworkVisualizer {
  constructor(container, networkConfig) {
    this.scene = new THREE.Scene();
    this.renderer = new THREE.WebGLRenderer({ antialias: true });
    this.camera = new THREE.PerspectiveCamera(75, 1, 0.1, 1000);
    
    this.initRenderer(container);
    this.createNetwork(networkConfig);
    this.animate();
  }

  createNetwork(config) {
    const layers = config.layers;
    const nodeGeometry = new THREE.SphereGeometry(0.1, 16, 16);
    
    layers.forEach((layerSize, layerIndex) => {
      const layer = new THREE.Group();
      
      for (let i = 0; i < layerSize; i++) {
        const node = new THREE.Mesh(nodeGeometry, this.getNodeMaterial(i));
        node.position.set(
          layerIndex * 2,
          (i - layerSize / 2) * 0.5,
          0
        );
        layer.add(node);
      }
