The algorithm, which enables high-quality on-GPU rendering of fonts and GUIs using Bézier curves, had been patented since 2019 with expiration set for 2038. After a decade of commercial use, Lengyel decided the patent was no longer necessary. A GitHub repository with reference shader implementations and inline comments is available for developers to implement their own versions. This opens the door for open source game engines and other rendering projects to adopt the technique. ## Full article daily.dev links to this article rather than hosting it.
