PicoGK
PicoGK is a compact and robust geometry kernel
...The library uses a deliberately reduced but powerful instruction set for building computational geometry. It supports geometry generation through voxel fields, lattices, implicit shapes, meshes, and robust Boolean operations. It can be used as the foundation for advanced engineered parts such as heat exchangers, electric motors, bio-inspired structures, and rocket engine components. Overall, PicoGK is meant for developers and engineers who want programmable, repeatable, and highly expressive geometry creation for real-world manufacturing.
