Show HN: Inkwash, a watercolor sketching app and explanation

#1

Post by Yenrabbit »

I've made a drawing app based on my physical sketching practice, using fluid sim and some shader tricks to mimic watercolor-style ink washes. Best used on iPad or with a drawing tablet. The linked article shows how the core engine works, with plenty of little interactive demos. It was fun to make, sharing in hopes others find it fun too :)

looks beautiful! i wanted to bookmark it because sometimes i need to explain some geometry to my son, and i have to download some sketching app each time, but with this I could just open and paint. There's one problem however. When on mobile, the page does not hid the control panel (mode, ink, etc) and it takes a large portion of the screen.

Ah yeah that's not ideal, fixed. I like the menu sticking around on iPad, but it now gets out of the way on smaller phone screens. Thanks for the reminder, I'd been meaning to do this! (Also, tldraw.com is fantastic for quick+easy diagrams and works great on mobile if you want a better whiteboard that isn't so art-focused :) )

Nice visualizations - have you tried Rebelle? They have an online version that lets you play with the watercolor/brushes of the painting software so you can see the colors drying on the canvas. https://www.escapemotions.com/experiments/rebelle/index.php

Oooh yeah I forgot how incredible that was! They really put care into how the pigments mix and move. I used to love watching timelapses of people doing art in rebelle.
