A library to import and export various 3d-model-formats including scene-post-processing to generate missing render data.
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.
Please check the latest documents at Asset-Importer-Lib-Doc.
This is the development repo containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from Github Assimp Releases.

open3mod is a powerful 3D model viewer based on Assimp's import and export abilities.
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)
/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/PostProcessing The post-processing steps
code/AssetLib/<FormatName> Implementation for import and export for the format
For more information, visit our website. 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 docs don't solve your problem, ask on StackOverflow with the assimp-tag. If you think you found a bug, please open an issue on Github.
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.
