libfive
Open-source framework for solid modeling using functional representations and signed distance fields, particularly suited for parametric and procedural CAD design. Libfive represents geometry as mathematical functions rather than boundary meshes, enabling infinite resolution, clean boolean operations, and smooth blending between shapes impossible with traditional mesh-based CAD. The framework includes Studio, a GUI application where users write Scheme or Python scripts to define geometry with real-time 3D preview and automatic meshing for export to STL or other manufacturing formats. Its functional approach makes it naturally parametric — changing any variable instantly regenerates the entire model without the topology failures common in history-based CAD systems. Computational designers and engineers use it for generative design, lattice structures, and complex organic forms that would be impractical to model manually.
