# 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.

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.

This research project was undertaken as part of work was supported by the UK’s Engineering and Physical Sciences Research Council [EP/K008196/1]. Sixteen undergraduate students performed sketching tasks using “Gravity Sketch 3D” (GSVR) and the HTC Vive VR system in a physical area of 2.5 by 2 metres. All VR sketches were screen recorded using a VR-capable laptop computer. A wide-angle video camera was used to record the participants’ physical actions as they moved around the room. Another video camera was positioned directly above a drawing board to capture the production of paper-based sketches. To record the participants’ utterances during the study, they wore a lapel microphone connected wirelessly to a radio receiver unit connected to the laptop. To facilitate review and analysis, the video recordings from the VR sketching sessions were edited to produce synchronized picture-in-picture videos showing the participants’ physical actions and the images they were producing with those actions (e.g. 3D sketches in VR).
