The Slug Algorithm has been around for a decade now, mostly quietly rendering fonts and later entire GUIs using Bézier curves directly on the GPU for games and other types of software, but due to its proprietary nature it didn’t see much adoption outside of commercial settings. This has now changed with its author, [Eric Lengyel], releasing it to the public domain without any limitations.
Originally [Eric] had received a software patent in 2019 for the algorithm that would have prevented anyone else from implementing it until the patent’s expiration in 2038. Since 2016 [Eric] and his business have however had in his eyes sufficient benefit from the patent, making it unnecessary to hold on to it any longer and retain such exclusivity.
To help anyone…
