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.

open3mod is a powerful 3D model viewer based on Assimp's import and export abilities. Assimp-Viewer is an experimental implementation for an Asset-Viewer based on ImGUI and Assimp (experimental).
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
