The Princeton Shape Benchmark
TLDR
It is concluded that no single descriptor is best for all classifications, and thus the main contribution of this paper is to provide a framework to determine the conditions under which each descriptor performs best. Expand
Poisson surface reconstruction
TLDR
A spatially adaptive multiscale algorithm whose time and space complexities are proportional to the size of the reconstructed model, and which reduces to a well conditioned sparse linear system. Expand
Rotation Invariant Spherical Harmonic Representation of 3D Shape Descriptors
TLDR
The limitations of canonical alignment are described and an alternate method, based on spherical harmonics, for obtaining rotation invariant representations is discussed, which reduces the dimensionality of the descriptor, providing a more compact representation, which in turn makes comparing two models more efficient. Expand
Screened poisson surface reconstruction
TLDR
This work extends Poisson surface reconstruction to explicitly incorporate the points as interpolation constraints and presents several algorithmic improvements that together reduce the time complexity of the solver to linear in the number of points, thereby enabling faster, higher-quality surface reconstructions. Expand
A search engine for 3D models
TLDR
A new matching algorithm is developed that uses spherical harmonics to compute discriminating similarity measures without requiring repair of model degeneracies or alignment of orientations and provides 46 to 245% better performance than related shape-matching methods during precision--recall experiments. Expand
Modeling by example
TLDR
This paper provides methods with which a user can search a large database of 3D meshes to find parts of interest, cut the desired parts out of the meshes with intelligent scissoring, and composite them together in different ways to form new objects. Expand
Reconstruction of solid models from oriented point sets
TLDR
A novel approach to the surface reconstruction problem that takes as its input an oriented point set and returns a solid, water-tight model by using Stokes' Theorem to compute the characteristic function of the solid model. Expand
A Complete Electron Microscopy Volume of the Brain of Adult Drosophila melanogaster
TLDR
Recon reconstructions of the entire brain of an adult female fly show that this freely available EM volume supports mapping of brain-spanning circuits, which will significantly accelerate Drosophila neuroscience. Expand
Modeling by example
TLDR
This paper provides methods with which a user can search a large database of 3D meshes to find parts of interest, cut the desired parts out of the meshes with intelligent scissoring, and composite them together in different ways to form new objects. Expand
Symmetry descriptors and 3D shape matching
TLDR
The empirical value of Symmetry Descriptors is demonstrated by showing that they improve matching performance in a variety of shape retrieval experiments, and it is shown that they can be computed efficiently using fast signal processing techniques. Expand
