this file you can find a simple but very effective algorithm for Nearest Neighbour Search which I megalomaniacly called the GLTree.
You want more? go to the Professional version of GLTree
It has been designed for uniformly random data, where is the fastest I ever used, but works fine even on sparse ones. If points are too sparse, for example logspace data, search is still performed correctly but speed can degenerate to a...

For those who wants more, a free-ware toolbox for surface recon is available here:
C++ source is now available.

InPolyedron detects points inside a manifold closed surface (even non convex ones). The normal orientation is assumed to be outwards. Warning there is no check for closed surface or normal orientation, open surfaces will give nonsense results.
Here you can find a simple tool to draw basic 3D spur gears feature. This tool is under development and collaboration is greatly appreciated. Several estention and improvements are possible. This can even be a basic brick for other graphical...
Gets the Volume enclosed by the surface defined by p,t,tnorm. The surface must be closed and manifold, there is no check for this.
The algorithm compute the volume of 3 tetraedrons for each triangle. The normals orientation define the sign of...
STL_Import is a tool designed to import into MATLAB both binary and ASCII STL files.
This script is mainly a collage between file exchange file id 22409 and 3642, plus some other features that can be considered new.
Even if totally m-coded, this routine is particularly fast in computing convex hull of 2D points. In many cases seems to be much faster than the matlab library routine. The main reason is that, differently from convhull, this algorithm jumps the...
Purpose of this program is studying a not standard section subject to torsional stress. Not standard means the section is not included in engineering Handbooks. It can be studied with FEM analysis with commercial softwares, but sometimes this can...
StructTriMesh is a tool to build structured triangular mesh on rectangle dataset. This is useful in avoiding delaunay 2D in
order to improve speed performances.
It can be used for graphical purposes, fem analysis, sedata structuresd-deTZ
