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

Open Asset Import Library is a library to load various 3d file formats into a shared, in-memory format. It supports more than __40 file formats__ for import and a growing selection of file formats for export.

APIs are provided for C and C++. There are various bindings to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.
Additionally, assimp features various __mesh post-processing tools__: 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.

### Other tools ###
[open3mod](https://github.com/acgessler/open3mod) is a powerful 3D model viewer based on Assimp's import and export abilities.
[Assimp-Viewer](https://github.com/assimp/assimp_view) is an experimental implementation for an Asset-Viewer based on ImGUI and Assimp (experimental).

#### Repository structure ####
Open Asset Import Library is implemented in C++. The directory structure looks like this:

	/code		Source code
	/contrib	Third-party libraries
	/doc		Documentation (doxysource and pre-compiled docs)
	/fuzz           Contains the test code for the Google Fuzzer project
	/include	Public header C and C++ header files
	/scripts 	Scripts are 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

The source code is organized in the following way:

	code/Common			The base implementation for importers and the infrastructure
	code/CApi                       Special implementations which are only used for the C-API
	code/Geometry                   A collection of geometry tools
	code/Material                   The material system
	code/PBR                        An exporter for physical-based models
	code/PostProcessing		The post-processing steps
	code/AssetLib/<FormatName>	Implementation for import and export of the format
