Open Asset Import Library (Assimp) is a cross-platform 3D model import library which aims to provide a common application programming interface (API) for different 3D asset file formats. Written in C++, it offers interfaces for both C and C++. Bindings to other languages (e.g., BlitzMax, C#, Python) are developed as part of the project or are available elsewhere.[2] Given the importance and the benefits of Assimp, a pure Java (/Kotlin) port is being developed here.

The imported data is provided in a straightforward, hierarchical data structure. Configurable post processing steps (i.e., normal and tangent generation, various optimizations) augment the feature set.[3]

Assimp currently supports 57 different file formats for reading, including COLLADA (.dae), 3DS, DirectX X, Wavefront OBJ and Blender 3D (.blend).[4] As of Version 3.0 Assimp also provides export functionality for some file formats.[5]

Projects using Assimp

Several open source projects use Assimp, such as MonoGame[6] and Urho3D.[7]

Torque3D added Assimp in Torque3D 4.0.[8]

Godot added Assimp in Godot 3.2,[9] but this was replaced in Godot 3.3 and later.[10][11]
