Free mesh software for mac

Mesh 1.13 is a simple to use, yet sophisticated tool that measures distortion between two discrete surfaces (triangular meshes). M.E.S.H. : Measuring Error between Surfaces using the Hausdorff distance. It uses the Hausdorff distance to compute a maximum, mean and root-mean-square errors between two given surfaces. Besides providing figures, MESH can also display the error values on the surface itself. Reads PYL, IV, SMF and raw data files.

Requirements:

• MacOSX 10.3 (or higher) Trolltech Qt framework

Enhancements:

• Added color-per-vertex and color-per-face support to U3D and IDTF file formats
• Added Convex Hull, Alpha shape, Voronoi Filtering, and Visible points filters
• Added Decoration filter to show camera position - Added Reflection Lines Shader to simply evaluate the mesh curvature. Notable bug corrections (since 1.2.0)
• Avoided crash in all filters based on marching cubes algorithm
• Substituted old IDTFConverter for Leopard with the new one provided by Michael Vidiassov (THANKS!)
• Added missing IDTFConverters dll file to Windows Installer.
• Cameras parameters check box in SaveMaskExporter dialog is only visible when you can actually save the parameters values. Improvements
• Now U3D plugin has its autogenerated form, like others io filters
• Added Help option in SaveMaskExporter dialog to visualize the IO parameters help info.

Requirements: Mac OS X 10.4 or later.

Gmsh - three-dimensional finite element mesh generator with built-in pre- and post-processing facilities.
Gmsh is an automatic 3D finite element grid generator (primarily Delaunay) with a build-in CAD engine and post-processor. Its design goal is to provide a simple meshing tool for academic problems with parametric input and advanced visualization capabilities.
Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmshs own scripting language.
Enhancements:
- added support for second order (curved) elements in
- post-processor;
- new version (1.4) of post-processing file formats;
- new stippling options for 2D plots;
- removed limit on allowed number of files on command line;
- all "Combine" operations are now available in the parser;
- changed View.ArrowLocation into View.GlyphLocation;
- optimized memory usage when loading many (>1000) views;
- optimized loading and drawing of line meshes and 2D iso views;
- optimized handling of meshes with large number of physical entities;
- optimized vertex array creation for large post-processing views on
- Windows/Cygwin;
- removed Discrete Line and Discrete Surface commands (the same functionality can now be obtained by simply loading a mesh in .msh format);
- fixed coloring by mesh partition; added option to light wireframe meshes and views;
- new "mesh statistics" export format;
- new full-quad recombine option;
- new Plugin(ModulusPhase);
- hexas and prisms are now always saved with positive volume;
- improved interactive entity selection;
- new experimental Tetgen integration;
- new experimental STL remeshing algorithm;
- various small bug fixes and improvements.

3DMF Workshop is able to import 3D models in OBJ or 3DS format and to export 3DMF files suitable for use with Rb3D. Features various mesh optimizing techniques plus a texture & surface attribute editor.

3DMF Workshop converts 3D models in OBJ or 3DS format to 3DMF. It also contains a material editor for applying textures and colors to individual meshes within a model.

Celestia is a free real-time space simulation that lets you experience our universe in three dimensions. Unlike most planetarium software, Celestia doesnt confine you to the surface of the Earth.
You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All travel in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across.
A point-and-goto interface makes it simple to navigate through the universe to the object you want to visit.
Enhancements:
- Windows: Added time zone selection to set time dialog
- Windows: Fixed hard to read text in set time dialog (bug was only present for certain Windows shell appearance settings.)
- Changed maximum number of eclipse shadows in OpenGL 2.0 path from two to three; if max is exceeded, clamp to three rather than not rendering the shadows at all.
- Corrected a bad calculation in ring shadow shaders that caused ring shadows to be drawn in the wrong place.
- Windows: Fixed the minimum feature size slider in the locations dialog so it updates in response to all the standard controls.
- Added a correct InfoURL for the Moon
- Windows: added splash screen with a progress indicator
- KDE: fixed some AMD64 bugs
- GTK: added splash screen with a progress indicator
- GTK: Added configure options to enable or disable Cairo support for splash
- Corrected a local flashing of the Milky Way brightness.
- Now the distance to the galaxy center is displayed, if the observer is located inside the galaxy (Milky Way...).
- Eliminated various incorrect Hubble type acronyms in deepsky.dsc that had penetrated the PERL filter.
- Add the corrected PERL script deepsky.pl.
- Mac: Universal binary - runs natively on Intel and PPC
- Mac: OpenGL 2.0 render path should now work on many configurations (requires OS X 10.4.3 or later)
- Mac: Offer option to disable vertex programs automatically when ATI Radeon 9200 renderer is detected (avoids hard crash)
- Mac: Progress message and version number displayed on splash screen
- Mac: Couple of French translation fixes
- Mac: Changed wording of "Subtract Light Travel Delay" menu item to "Add/Subtract Light Travel Delay" to more accurately reflect its function

- Removed several files from installation on Linux and MacOS, saving ~5M compressed.

Planet Discordia is generated entirely for scratch by first tesselating a sphere into triangles, then perturbing it with fractal noise and smoothing.

Finally, the mesh is colored based on altitude relative to sea level.

C++ source code using OpenGL / GLUT is included.
