Open Asset Import Library (Assimp) is a C/C++ library that imports 40+ 3D model file formats (FBX, glTF, Collada, OBJ, STL, and more) into a unified in-memory data structure, with export support for a growing set of formats. It also provides mesh post-processing tools such as normal/tangent generation, triangulation, and vertex cache optimization, with bindings for Python, C#, Java, and D.

Use cases

• load fbx models in c++
• import gltf files into a game engine
• convert 3d model formats
• parse collada dae files
• generate normals and tangents for meshes
• load 3d assets on android or ios
• read stl files programmatically

When to choose

• you need to support many 3D file formats through a single API
• you are building a game engine, viewer, or asset pipeline in C/C++
• you want mesh post-processing like triangulation or normal generation built in
• you need cross-platform 3D asset loading including mobile

When to avoid

• you only need one specific format with a dedicated lightweight loader
• you need GPU-ready rendering rather than CPU-side scene data
• you require a permissively simple license review - the license is listed as NOASSERTION on GitHub despite the BSD claim on the homepage
