Compute volume and area of triangulation using divergence theorem of gauss in matlab

The following Matlab project contains the source code and Matlab examples used for compute volume and area of triangulation using divergence theorem of gauss . Computes the VOLUME and AREA of a closed surface defined by the triangulation in indices TRI and coordinates X, Y and Z, using the divergence theorem of Gauss (volume/surface integral).

Exports triangulations and triangulated surfaces to vtk file format. in matlab

The following Matlab project contains the source code and Matlab examples used for exports triangulations and triangulated surfaces to vtk file format. . Creates vtk files from triangulations/tetrahedralizations in standard format (delaunayn.m output). Additionally vertex or cell data can be added. This is useful for visualizing and postprocess triangulations/tetrahedralizations and/or related functions with the help of paraview.

Calculates the volume under a surface defined by scattered points in matlab

The following Matlab project contains the source code and Matlab examples used for calculates the volume under a surface defined by scattered points . scatterquad2(X,Y,Z) finds the volume under the surface defined by the points (X(i),Y(i),Z(i)) with linear interpolation on the Delaunay triangulation of (X,Y) and Z=0 outside the convex hull of (X,Y).

Alpha shapes in matlab

The following Matlab project contains the source code and Matlab examples used for alpha shapes. Computes the basic Alpha shape of a 2D/3D point set by Delaunay triangulation. OUTPUT: - Area/Volume - Triangulation of Alpha shape - Boundary of Alpha shape - Plot

Hyperbolyc triangulations in matlab

The following Matlab project contains the source code and Matlab examples used for hyperbolyc triangulations. A tool to generate an evolve and visualize triangulations on surfaces with arbitrary genera by using four elementary moves: T1 - switch neighbors T2 - add a vertex aT2 - remove a vertex g1 - add an handle increasing the genus of the surface by one The triangulation can be generated with desired degree distribution.

Intriangulation which points are inside a 3d watertight triangulation? in matlab

The following Matlab project contains the source code and Matlab examples used for intriangulation which points are inside a 3d watertight triangulation?. How often does this happen: You have a nice mesh in 3d, which is described by an np by 3 array of vertices and an nt by 3 array of indices into this array, which describe the faces.

A fast image segmentation using delaunay triangulation (revisited) in matlab

The following Matlab project contains the source code and Matlab examples used for a fast image segmentation using delaunay triangulation (revisited). This is a tuned version of the old post on Delaunay-based image segmentation. http://www.mathworks.nl/matlabcentral/fileexchange/28330-a-fast-image-segmentation-using-delaunay-triangulation
