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.

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/PostProcessing     The post-processing steps
code/AssetLib/<FormatName>  Implementation for import and export for the format
