QTetraMesher 0.8.3

ScreenShot ScreenShot

This is a Qt-based program for Windows and Linux to generate tetrahedral meshes for finite element simulation from various surface mesh formats. It also offers a fast and easy-to-use mesh viewer based on QGLViewer and allows basic mesh manipulations (currently only scaling is possible). Two different methods for tetrahedralization are possible: Delaunay Triangulation and two variants of Johnathan Shewchuk's Isosurface Stuffing algorithm.

As I am using lots of 3rd-party open-source C/C++ libraries, this work is released as GPL software. This includes all self-written code. 3rd-party code remains under its own license.

Changelog

0.8.3 - 2023-12-16

Updated Windows binary build (Visual Studio 2019 Community, x64)

Functional updates:

  • Full CMake build! All projects can now be built with CMake. (Pretty easy on Linux, but a PITA on Windows...)
  • Significantly improved mesh surface mesh loading + speed:
  • Replaced old trimesh2 C library with Assimp library
  • New mesh formats available for import
  • Fixed surface normal generation (damn.. the old one was so slow...)
  • libQGLViewer is now included in the repo and not required as an external dependency anymore

0.8.2 - 2018-05-27

0.8.1 (Source only) - 2015-12-06

  • Migration to Github due to cancellation of Google Code

0.8.1 - sometimes in 2014... (Googlecode's history is lost)

  • Drag & Drop supported mesh files on the main window to open files.
  • Octree generation and visualization as a preparation for own Isosurface Stuffing implementation.

Features

  • As of 2024-06-01 this project can now be built with Qt6 (at least on Linux)
  • Runs on Windows and Linux (tested on Win7 (32/64 bit), WinXP (32 bit) and Ubuntu 12.04/12.10/.../22.04, Arch based Manjaro 2024-05, Fedora 40).
  • Integration of QGLViewer for easy mesh preview.
  • Surface mesh import and export for *.obj, *.ply, *.off, *.stl (using assimp).
  • Import and export of tetrahedral meshes in (a simplified subset of the) GMSH format *.msh (compatible with the SOFA Framework).
  • Two different methods for tetrahedralization: Delaunay Triangulation (CGAL implementation) and Johnathan Shewchuk's Isosurface Stuffing: Fast Tetrahedral Meshes with Good Dihedral Angles (implementation taken from the SOFA Framework, non-graded variant only).
  • Wireframe and solid/shaded drawing.
  • Cutplane view for tetrahedral meshes.
  • Export the surface of a tetrahedral mesh.
  • Automatic parameter guessing for tetrahedralization.
  • Reversible scale mechanism for CGAL performance optimization.
