Software Listing: Triangulation

TRIANGULATION performs triangulation of a set of 3D points width compulsory interconnections between the points. The outcome is represented by 3DFACE entities. ISOLINES determines the curves of intersection of a set of 3DFACE entities width a set of plane equidistances horizontally or vertically. The outcome is made up of POLYLINE entities optionally interpolated. VOLUME determines volume and center of gravity of a body limited by 3DMESH and 3DFACE entities. 3DINTERSECTION determines the intersection curves between 2 sets consisting of 3DFACE or 3DMESH entities. The outcome is represented by 3DPOLY entities.

An add-on for AUTOCAD 2002-2018, which makes the triangulation of a set of POINT entities, the intersection curves (isolines) between a set of 3DFACE entities and a set of equidistance plans, horizontally or vertically and the volume and center of gravity of a set of bodies or between surfaces composed of 3DFACE entities. You can also load and draw a file of points having the format: Number X Y Z Code. The drawing of the XYZ files is made with POINT, 3DPOLY, SPLINE or BLOCK entities, according to a modifiable library of codes. The triangulation is performed on a convex hull of a set of points.

The program runs on Autocad 2007/2008/2009 32bits, Autocad 2010 32bits, Autocad 2009 64bits, Autocad 2010 64bits, and BricsCAD v10.
Geographical information.- You can draw the DTM of all the world, because the program is compatible with SRTM format and it download the files by you and draws the result.
Professional.- It's not only a program to calculate a delaunay triangulation but you can insert break-lines to get a representation of the real terrain.
History.- The first version of this program came onto the market in 1992 and there are more of 3000 professionals working with it, civil engineers, architects, foreman builders, surveyors, mathematics, etc.

This program uses the Delaunay triangulation of a set of 2d points to generate a set of triangles that will make for a good terrain. Notice how there are more triangles on the bottom than at the top. This means it can offer more terrain detail close to the viewer and less further away once the terrain is lifted into 3d. This program requires CGAL from http://www.cgal.org/ to compile..

Trying to visualize a huge triangulation with trisurf or triplot is often very slow and frustrating. Solution : use Paraview, a very powerful and free 3D data viewer. But it could be complicated to generate the input file specially with binary format. The function proposed takes a 2.5D unrestricted triangulation and generates the ASCII VTK file for Paraview. function exportTriangulation2VTK(file,XYZ,tri,dir) Input : "dir" is the path of the directory where the file is saved (string). (Optional) "file" is the name without extension of the file (string). "XYZ" is the coordinate of the vertex of the triangulation (nx3 matrix).

This is a handy and reliable application designed to generate (constrained) Delaunay triangulations and quality meshes of point sets or planar straight line graphs.

Delaunay Triangulation also features a mesh statistics utility that displays an angle histogram.

Simple, powerful and inexpensive CAD software for surveying. You can do triangulation, isolines, color-filled contour maps, sections, intersections, volume and much more. You can process hundreds of thousands of points or triangles, even on less powerful PCs. Through its own CAD system (called RCAD), specialized for 3D and for a large number of entities, you can: -load and draw a file of points having the format: Number X Y Z Code; the drawing is made by POINT,3DPOLY,SPLINE or BLOCK entities, according to a modifiable library of codes -edit interactively the XYZ files of points; you can modify the coordinates, the code and the position (in 3DPOLY or SPLINE) -triangulate the points on a convex hull or between an external contour and possibly more interior contours -do isolines (contour lines) and color-filled contour map -do...

This submission is for Matlab beginners. After I post my tools on surface recostruction I received many e-mails of people asking what is the best way to get a surface from 3D scatter. Most of them (about 90%), show to me surfaces in the z=f(x,y) form. File exchange offers many alternative in this case, one of them is John D'Errico's gridfit that returns very smooth and good looking surfaces. My tools for surface recostruction are designed for the more general, and of course complicate, case when the surface is not in the z=f(x,y). Unfortunatly they are not reliable as gridfit or the method I am going to show.

In the past several years compact radio navigation receivers have proliferated in the civilian market place, generally under the name of GPS or Global Positioning System. Appearing as handheld units or built into cars, mobile phones, and airplanes, these commercial applications originated from a Cold War military application. GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites, each in its own orbit 11,000 nautical miles above the Earth, and five ground stations that make sure the satellites are working properly. The GPS satellites each take 12 hours to orbit the Earth.

StructTetraMesh is a tool to build structured tetreaedral mesh on cuboid dataset. This is usefull in avoiding delaunay 3D triangulation that for this kind of dataset are particularly slow and numerically unstable. This tool allows a huge speed improvement against delaunayn for 3D points, the output triangulation will also be 'slivers-less', this is particularly important for programs that need a conform triangulation like fem analysis and search structure algorithms. INPUT: x,y,z must be vectors, they represent the axis of the cuboid. It is also very important they need to be sorted. To improve performances there is no check for sorted vectors so you have to check yourself.
