Importing and exporting mesh data between MATLAB and MeshLab

Given a 2D surface embedded in 3D, I generate its Delaunay triangulation using MATLAB's delaunay and delaunayTriangulation methods. However, they do not produce good watertight results.

I save the triangulation mesh saved as list of vertices x in 3D and list of triangles T (each row is a triangle, in which there are 3 indices, refering to the vertices in x (e.g. T(i) = [3 7 15] is the triangle with vertices x(3), x(7) and x(15)).

I want to export this data to MeshLab, edit and fix it there, and then import the result from MeshLab back to MATLAB. Is it possible? Does MeshLab support in MATLAB? If so, how to import and export the data?

Hello, were you able to solve it in any way? 

[stefano Chiappini]

hI, i have the same problem. I want to export the output by mesh algorthim from Matlab to CloudCompare.

Did you solve the problem? if yes, can you show me the code?

Thank you so much.

Using stlwrite one can write MATLAB triangulations into a STL file.

Using stlread one can read an STL file into a MATLAB triangulation.
