Gmsh is described as '3D finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities' and is an app in the Photos & Graphics category. There are more than 25 alternatives to Gmsh for a variety of platforms, including Windows, Linux, Mac, Android and Windows Phone. The best alternative is Blender, which is both free and Open Source. Other great apps like Gmsh are Wings 3D (Free, Open Source), Autodesk Maya (Paid), Autodesk 3ds Max (Paid) and Rhinoceros (Paid).
Wings 3D is a subdivision modeler inspired by Nendo and Mirai from Izware. It is possible to assign materials, vertex color, UV coordinates and textures, but there will be improvements in those features before Wings goes 1.0.
Rhino can create, edit, analyze, document, render, animate, and translate NURBS* curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size beyond those of your hardware.
ZModeler (or Zanoza Modeler) is a 3D modeling application. It is aimed at modelers who model for computer games such as 18 Wheels of Steel, Grand Theft Auto, Need for Speed, Midtown Madness or similar video games.
AC3D is one of the longest established 3D design software programs available today. In development from 1994 and commercially available since 1996, AC3D has grown to become a highly regarded and popular program.
