xatlas is a small C++11 library with no external dependencies that generates unique texture coordinates (UV unwrapping) for 3D meshes. It is an independent fork of thekla_atlas, used for baking lightmaps and texture painting.

Use cases

• generate UV coordinates for 3D meshes
• create texture atlases for baking lightmaps
• unwrap meshes for texture painting
• parameterize charts of a 3D model
• prepare game assets for lightmap baking
• pack mesh charts into a texture atlas

When to choose

• you need UV unwrapping in a C++ application with no external dependencies
• you are baking lightmaps or generating texture atlases for game engines
• you want a proven library descended from thekla_atlas used in The Witness
• you need a simple three-step API (create, add meshes, generate)

When to avoid

• you need interactive UV editing in a DCC tool rather than automated unwrapping
• you need a GPU-accelerated or highly parallel solution
• you need bindings for languages other than C++ or Python without writing your own
