1. assimp(Open Asset Import Library)简介

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.

Open Asset Import Library是一个将各种三维文件格式加载到共享内存格式中的库。它支持40多种文件格式的导入和越来越多的文件格式的导出选择。

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.

为C和C++提供了API。有各种与其他语言（C#、Java、Python、Delphi、D）的bindings。Assimp也运行在Android和iOS上。此外，assimp还提供了各种网格后处理工具：法线和切线空间生成、三角测量、顶点缓存位置优化、删除退化基本体和重复顶点、按基本体类型排序、合并冗余材质等等。

8.其它工具(Other tools)

open3mod is a powerful 3D model viewer based on Assimp's import and export abilities.

9.仓库结构(Repository structure)

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

/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 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 for the format
