This 3D model of Zilker Rock was generated using Photoscan Pro photogrammetry software 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).
If you’ve been in Austin a while and like to visit our parks, you probably know this rock.
