Click above for a 700 x 700 pixel version | A computer rendering made from a 3D model of Michelangelo's David. The modelwas built by scanning the statue using a laser triangulation rangefinder andassembling the resulting range images to form a seamless polygon mesh. Themesh contains 8 million polygons, each about 2.0 mm in size. The raw data fromwhich the mesh was built contains 2 billion polygons, representing rangesamples spaced 0.25 mm apart on the statue surface. Although we also digitizedthe statue's color, the veining and reflectance shown here are artificial. Therendering includes simulated subsurface scattering, but with arbitraryparameters.

David Statue 3D model. Add to wish list Remove from wish list. Description; Comments (0) Reviews (0) David is a masterpiece of Renaissance sculpture created in marble between 1501 and 1504 by the Italian artist Michelangelo. David is a 5.17-metre marble statue of the Biblical hero David, a favoured subject in the art of Florence. Download files and build them with your 3D printer, laser cutter, or CNC.

Abstract:
David Statue 3d Model Maker
We describe a hardware and software system for digitizing the shape and colorof large fragile objects under non-laboratory conditions. Our system employslaser triangulation rangefinders, laser time-of-flight rangefinders, digitalstill cameras, and a suite of software for acquiring, aligning, merging, andviewing scanned data. As a demonstration of this system, we digitized 10statues by Michelangelo, including the well-known figure of David, two buildinginteriors, and all 1,163 extant fragments of the Forma Urbis Romae, a giantmarble map of ancient Rome. Our largest single dataset is of the David - 2billion polygons and 7,000 color images. In this paper, we discuss thechallenges we faced in building this system, the solutions we employed, and thelessons we learned. We focus in particular on the unusual design of our lasertriangulation scanner and on the algorithms and software we developed forhandling very large scanned models.
