meshoptimizer is a mesh optimization library that makes meshes smaller and faster to render.
The library addresses the challenge of preparing triangle mesh data for efficient GPU rendering. Modern graphics pipelines process vertex and index data through multiple stages, and performance depends heavily on how that data is structured. meshoptimizer provides algorithms to optimize meshes for GPU pipeline efficiency, reduce mesh complexity through simplification, and decrease storage overhead through compression. It exposes these capabilities through C and C++ interfaces, with additional language bindings available through FFI, a Rust crate, and JavaScript bindings.
The tool suits projects that need to optimize 3D mesh assets for real-time rendering, particularly those working with glTF files. A companion command-line tool called gltfpack automates optimization of glTF files directly. The library is also distributed as packages across multiple Linux distributions and through Vcpkg and Conan, making integration straightforward for most build systems. Developers can either use CMake to build it as a standalone or embedded library, or add individual source files directly to their build system depending on which algorithms they need.
Development activity shows consistent maintenance with automated testing via continuous integration and code coverage tracking. The project provides pre-built binaries for gltfpack and maintains availability through multiple package managers and distribution channels, indicating sustained attention to accessibility and usability across different platforms and workflows.
