# The 2D shape structure dataset: A user annotated open access database #### A Carlier, K Leonard, S Hahmann, G Morin, M Collins This code was tested on Matlab R2015a, on Ubuntu 14.04 and on Mac OS 10.9.5.

Extrinsic - Zhiyang Huang (2016) ------------------------------------ This code implements the algorithm described in Huang Z, Ju T. Extrinsically smooth direction fields. Comput Graph(2016), http://dx.doi.org/10.1016/j.cag.2016.05.015i The basic function of this program is to compute extrinsically smooth direction fields “g” upon a curve, surface or volume while giving a references field “f”, such that “g” is orthogonal to “f”. In particular, the default setting of “f” for curve and surface are tangent field of the curve and normal field of the surface, respectively. The parameter-free initialization method based on least eigenvector problem and the Gauss–Seidel iterations, as described in the above paper, are implemented in this code and subjected to use. Currently the code is only tested on Mac OS X 10.10 or above, it should work at other platforms with minor modification.

# PinMesh PinMesh is an exact and efficient parallel algorithm for preprocess a polyhedral triangular mesh and, then, query a cloud of points against the mesh. PinMesh is described in the following paper: Magalhães SVG, et al. PinMesh - Fast and exact 3D point location queries using a uniform grid.
