Here is a 3D scan of a pumpkin. The pumpkin was captured with 16 photographs at 16 megapixel resolution and then reconstructed using photogrammetry techniques, producing a high resolution 3D mesh model and a diffuse texture map. The mesh was then simplified to a low polygon mesh and a normal map was baked based on the high polygon mesh.
Here is the pumpkin rendered in realtime. Below is the original photo.
