QTetraMesher 0.8.5

available at https://github.com/dennis2society/qtetramesher/releases/tag/0.8.5

Changelog

• New tetrahedralization methods:
  • Custom GenericIsoSurfaceStuffing implementation with optional graded tetrahedra (results vary with mesh size and selected cell size) with no external dependencies
  • Improved Tetgen integration
  • GMSH integration (this one is sensitive to surface mesh quality…
  • ftetwild integration
• Surface mesh quality check (basic test for usage with Tetgen and GMSH)
• libQGLViewer replaced by the new lightweight QtmGLViewer (QOpenGLWidget, OpenGL 3.3 core profile, shaders and GPU buffers). Works natively in Wayland.
• Two lights (headlight and a softer light from above) for better shape perception
• Visualization options (colors, wireframe/solid options, surface mode, axis/grid/bbox) are saved and restored between sessions
  • Now with different surface/inside colors for tetra meshes
• Fixed: bounding box was not updated when the surface mesh was moved to the origin
• Robustness: failed or corrupt mesh files (surface, GMSH, Tetgen) are rejected with a message and keep the current mesh instead of crashing; Generate without a loaded surface no longer crashes; failed tetrahedralization keeps the surface visible
• Fixed memory leaks (octree, file stream in the GMSH loader, Tetgen parameters)
• GMSH files must be ASCII MSH version 2 (version 4 files are now detected and reported)
• Tetrahedralization no longer blocks the UI: each method runs in a separate worker process and can be canceled (also when a method hangs); a crash in a method no longer takes down the program.
  Octree generation and the surface check run in background threads. A progress indicator is shown in the viewer
• Fixed a bug in the cutplane rendering (initial slider values were not at 0 cutting off parts of the tetrahedra mesh)
• Improved surface mesh loading including optional basic mesh repair on load
• Better about and help dialog
• Added an application icon
