Repaint – a WebGL based website builder▲236
Hey HN! We're Ben and Izak, founders of Repaint (YC S23). Repaint is like Figma, but for creating real websites. It has panning, zooming, and dragging elements around. The settings closely follow html/css. We think an open canvas is a big improvement over other website builders. Everything is easier: styling, consistency, responsiveness… But making it work was hard! We thought HN would appreciate the tech behind it: - A custom WebGL rendering engine (w/text, shadows, blurs, gradients, & opacity groups) - A partial implementation of the css spec - A custom text editor & text shaper…

Krita RGBA Tech – Bringing Realistic Metal to Life in Open-Source Art▲271
Krita's v4.2+ RGBA brushtips let you paint with dimensionality, and it's a technology that Photoshop doesn't have (≖‿ゝ≖) It lets the creator do things like emulating light direction, making brushstrokes look 3D. I used them to make a set of metallic brushes. If there are any FOSS artists around, feel free to test them out. (p.s. Yes, I am learning Github so I probably made repository mistakes - apologies in advance lol)
