Ink and Switch Constraint System (2023)

At the beginning of phase 2, we weren’t sure what to do about constraints. Based on past exploration, constraints seemed to hold a lot of promise but were notoriously unreliable. A good constraint system could unify and power a number of key aspects of the dynamic medium we seek.

It would allow for a computational model that bridged between algebraic formulae and tangible objects, like an architectural drawing that changed in response to edits in a parameter table. This early success built on his earlier work on [ propagation of knowns] to reduce the number of variables whose values had to be determined by the solver. We hope to eventually try @Avi Bryant 's new solver which uses auto-diff (instead of numerical differentiation) and WebAssembly for added performance and stability.
