Implementations of both methods are currently available fordownload, respectively, atZipPack andVripPack.The second method is the surface reconstruction method invoked by theScanalyze software package used in theDigital Michelangelo Project.Another software package that might be of interest isVolfill, our diffusion-based hole filler forlarge polygon meshes. The entry for each model indicates whichmethod was used.
Finally, thealigned range images are combined to produce a single triangle mesh (a processsometimes called surface reconstruction) using eitherzippering or volumetric merging,two methods developed at Stanford. For all the Stanford models,alignment was done using a modified ICP algorithm, as described inthis paper.These alignments are stored in '.conf' files, which list each range image inthe model along with a translation and a quaternion rotation. To merge these range images, we mustfirst align them together. Each scan takes the form of a range image, described in thelocal coordinate system of the scanner. These last twomodels were acquired using Brian Curless's spacetimeanalysis.
Thetriangulation calculations all the Stanford models except the Happy Buddha andDragon were performed in hardware by the Cyberware scanner(s). The first set of models below, called 'The Stanford Models', were scanned witha Cyberware 3030 MS scanner, with theexception of Lucy, who was scanned with theStanford Large Statue Scanner, designed for theDigital Michelangelo Project.Both scanners are swept-stripe, laser triangulation range scanners.
