TriMesh2: C++ library and set of utilities for input, output, and basic manipulation of 3D triangle meshes

This is a fork of the trimesh2 library (originally by Szymon Rusinkiewicz), which I use a lot in my other graphics projects. I'm staying close to the original, and adding my fixes for MSVC compilation. See further down for details.

• For the Trimesh2 project, see the original Trimesh2 homepage.
• Original MSVC 2012 project by Bengt Rosenberger.

Features:

• Support for reading/writing PLY, OFF, OBJ files. Read-only: 3DS, SM, RAY.
• Vec: a templated C++ class for constant-length vectors, with support for the usual arithmetic operations
• XForm: a class for rigid-body transformations.
• An OpenGL trackball/arcball implementation, with automatic selection of rotation center.
• Algorithms for subdivision, smoothing, curvature estimation, triangle stripping, and various other simple mesh manipulations.

The following utility programs are included:

• mesh_view: a simple 3D mesh viewer
• mesh_make: create arbitrarily-tessellated meshes of various simple shapes
• mesh_filter: applies a variety of simple transformations to a mesh, such as converting formats, flipping faces, subdivision, smoothing, rigid-body transformations, etc.
• mesh_cc: list and/or extract connected components from a mesh
• mesh_cat: combine several meshes into a single file
• mesh_align: align 2 meshes using ICP
• mesh_shade: a few procedural shaders for adding per-vertex color
• mesh_check: check for some kinds of topological oddities (e.g., more than 2 faces at an edge) in a mesh file.
• mesh_crunch: quick-n-dirty mesh decimation using the Rossignac-Borrel method of vertex collapse
• mesh_info: print out some information about a mesh
• xf: create or compose transformations in .xf files

Notable changes/additions to vanilla trimesh2

• Fixes for MSVC 12.0 / 14.0 compilation
• MSVC project for Visual Studio 2013 professional
• MSVC project for Visual Studio Community Edition 2015
• Fixes for OpenMP compilation in VS 2015
• Fixes for FreeGlut / Gluit compilation in VS 2015
• Added (experimental) 64-bit MSVC compilation support

Todo

• Build trimesh2 tools (mesh_view, etc.) using MSVC project
