About:
Assimp (Open Asset Import Library) is a portable library that imports 3D models from dozens of file formats into a unified, in-memory data structure. It normalizes data for easy consumption by rendering engines and tools, handling animations, materials, and geometries. Its primary value is providing a single, stable API to support a wide variety of legacy and modern 3D assets.

Key Features:

Supports over 40 3D file formats for import and export
Unified scene structure (aiScene) simplifies data access
Post-processing steps for geometry optimization and data cleanup
Written in C++ with bindings for C, C#, Python, and other languages

Use Cases:

Loading diverse 3D assets in game engines and editors
Building asset pipelines for conversion and optimization
Scientific visualization and CAD data interoperability

Alternatives:

OpenSceneGraph – Full 3D graphics toolkit; Assimp is focused solely on asset import
FBX SDK – Autodesk's SDK for FBX; Assimp is open-source and supports many more formats
tinygltf – Lightweight glTF loader; Assimp is broader in scope and supports many non-glTF formats
