Poncho - 3D Model Display

• Scene Setup: Initializes the scene, camera, and renderer.

• Lighting: Adds ambient, directional, and hemisphere lights to illuminate the model.

• Model Loading: Uses THREE.GLTFLoader to load the GLB file (source/Porsche.glb). The loader will automatically handle the textures embedded in the GLB.

• Animation Loop: Continuously renders the scene using requestAnimationFrame.

• Responsive Design: Adjusts the renderer size when the window is resized.

• Bounding Box Calculation: After loading the model, a bounding box is calculated using THREE.Box3().setFromObject(model).

• Position Adjustment: The model's position is adjusted based on the bounding box's center and size to ensure its base aligns with the grid. The Y position of the model is set to ensure its bottom aligns with Y=0 (ground level).
