Yosemite Valley's Cathedral Spires 3dTopo

thingiverse

A highly detailed 3D topography of Yosemite Valley's Cathedral Spires is presented here. The model is so precise that it shows even the ledge on the classic climbing route of Lower Cathedral Spire. It was derived from a LIDAR dataset, which was collected to study nitrogen export and made available at http://opentopo.sdsc.edu/. This dataset was gridded into 0.5m resolution. A tutorial video on its creation is available at https://www.youtube.com/watch?v=t4-ICkvyJv0, where it is also revealed that the print took 22 hours. It was sliced with Simplify3d at default high quality settings and printed in PLA on a FlashForge. The model used 6 shells, no infill and no bottom. If you desire a model of the entire Cathedral Rocks area, it is available on Thingiverse under http://www.thingiverse.com/thing:285886. This 3D print also made it to the 3D Printing Today podcast, accessible through iTunes, Stitcher radio or directly from its source at http://threedprintingtoday.libsyn.com/.
