I'll create a 3D viewer to render your cartoon pony car model. Let me set that up for you with controls to interact with the model.

The 3D viewer is now set up to display your cartoon pony car model. Here's what I've created:

1. A 3D viewer component using React Three Fiber and Three.js

2. Interactive controls that allow you to:

   • Rotate the model by dragging with your mouse
   • Zoom in/out with the scroll wheel
   • Pan by right-clicking and dragging
   • Toggle auto-rotation with a button

The model is displayed in a clean, modern UI with a gradient background and a white container for the 3D viewer. The car is properly lit with an environment map to show off its details.

I'll remove those elements while keeping the core 3D viewer functionality intact.

I've simplified the 3D viewer by removing:

1. The blue gradient background
2. The heading ("3D Pony Car Viewer")
3. The instruction text at the bottom
4. The auto-rotate button

The core 3D viewer functionality remains intact - the model will still auto-rotate by default, and you can still interact with it using mouse controls (rotate by dragging, zoom with scroll wheel, and pan with right-click and drag).
