If you've been in Austin a while and like to visit our parks, you probably know this rock.
This 3D model of Zilker Rock was generated in PhotoScan Pro from over 700 individual aerial and terrestrial photographs (20Mpixels+ each image) . The model has been decimated from over 20M triangles, down to about 5M for sake of file/download size (model is still just under 200MB so may take a few secs to load depending on your internet bandwidth).
