Open Asset Import Library (assimp) 
========

Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a shared, in-memory format__. It supports more than __30 file formats__ for import and a growing selection of file formats for export. Additionally, assimp features various __post processing tools__ to refine the imported data: _normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials_ and many more.

This is the development trunk of assimp containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [assimp.sf.net](http://assimp.sf.net) or from *nix package repositories. According to [Travis-CI] (https://travis-ci.org/), the current build status of the trunk is [![Build Status](https://travis-ci.org/assimp/assimp.png)](https://travis-ci.org/assimp/assimp)

[open3mod](https://github.com/acgessler/open3mod) is an Open Source 3D model viewer based off Assimp's import and export abilities.

#### Repository structure ####


Open Asset Import Library is implemented in C++ (but provides both a C and a 
C++ish interface). The directory structure is:

	/bin		Folder for binaries, only used on Windows
	/code		Source code
	/contrib	Third-party libraries
	/doc		Documentation (doxysource and pre-compiled docs)
	/include	Public header C and C++ header files
	/lib		Static library location for Windows
	/obj		Object file location for Windows
	/scripts 	Scripts used to generate the loading code for some formats
	/port		Ports to other languages and scripts to maintain those.
	/test		Unit- and regression tests, test suite of models
	/tools		Tools (old assimp viewer, command line `assimp`)
	/samples	A small number of samples to illustrate possible 
                        use cases for Assimp
	/workspaces	Build enviroments for vc,xcode,... (deprecated,
			CMake has superseeded all legacy build options!)



### Building ###


Take a look into the `INSTALL` file. Our build system is CMake, if you already used CMake before there is a good chance you know what to do.


### Where to get help ###


For more information, visit [our website](http://assimp.sourceforge.net/). Or check out the `./doc`- folder, which contains the official documentation in HTML format.
(CHMs for Windows are included in some release packages and should be located right here in the root folder).

If the documentation doesn't solve your problems, 
[try our forums at SF.net](http://sourceforge.net/p/assimp/discussion/817654) or ask on
[StackOverflow](http://stackoverflow.com/questions/tagged/assimp?sort=newest).

For development discussions, there is also a mailing list, _assimp-discussions_
