Show HN: SDFY: Fast 2D Vector Shapes and Shadows with Signed Distance Functions

2 elcritch 0 6/9/2025, 10:04:05 AM github.com ↗

SDFY is weekend project I made using signed distance functions and some SIMD to quickly rasterize vector shapes and shadows for GUIs. Rendering drop and inset shadows is a relatively slow process using a standard 2D gaussian blur. Not being happy with the performance of existing renderers I made my own way.
