Hayden StainsbyFinal talk at @rustlab is a bittersweet moment.
#RaphLevien is explaining Vello, 2D rendering with #rust. Lots of great demos!
Pierre HuyghebaertJust updated our collection of blurbs about #vector curves with the new spline proposed by #Spiro author #RaphLevien on http://drawingcurved.osp.kitchen/r/spiro.md
In multiple links pointed by online discussions, I read about #KochanekBartels spline on https://en.wikipedia.org/wiki/Kochanek%E2%80%93Bartels_spline
Amazing to discover one after the other so many proposals to draw curves digitally, after #Euler, #Bezier, #Hobby (Metapost), Spiro, #κCurves and probably lots of others?

After a long sleep, a new post on OSP blog! The report of the Libre Graphics Meeting by @manetta http://blog.osp.kitchen/news/lgm-2019.html with the question of the word "open" by @aiscarvalho and @rlafuente, #education, #vectors, #RaphLevien and new curves for #typography, and #pagedjs inside. @lgm #lgm19
#RaphLevien is back on #vector #curves years after #spiro release

In the background, somewhere, #kcurves from #adobe

"κ-curve system was implemented as a tool in a commercial
illustration package, Adobe Illustrator. Adobe Illustrator is instrumented to report the amount of time users spend using each of the available tools. The new tool, called the “curvature” tool, is a direct competitor for the much older “pen” tool that uses cardinal splines. Even though there are experienced and exacting artists with many
years invested in the the pen tool, six months after the release of
the curvature tool 35% of the combined use of the two tools was with the newer curvature tool on desktop devices. On devices with touch screens, the curvature tool captured 66% of the combined use of the two tools. While more studies are needed to fully understand artists preferences, this usage data strongly suggests that our model
is a welcome addition to professional work–flows." #surveillance
Secrets of smooth Béziers revealed
I haven’t posted here much lately, and I admit, it’s because I’ve gotten sidetracked thinking about curves again. I did my PhD thesis on curves, so spent years thinking about them, then put that on hold for a while, aside from some work in crunching font file sizes down.
