Fidget (mattkeeter.com)

Article summary

Fidget is a library for representing, compiling, and evaluating large-scale math expressions, particularly implicit surfaces. It is designed as a backend for implicit surfaces and is written in Rust, allowing for easy cross-compilation to WebAssembly. The library uses a combination of interval arithmetic and tape simplification to optimize evaluation. Fidget has potential applications in computer-aided design, 3D printing, and other fields.
