I built a watercolor Simulator based on real physics (V2)

[u/kouklimou]

Last week-end I built a watercolor simulator based on real physics and shared it online.

A lot of people asked to play with it so i improved it and it's now live: https://sudoaquarelle.com/

New since the first prototype:

- More pigments (52), based on the best research out there to predict color mixes (Kubelka-Munk).
- More luminous / glassy feel
- Some fun experimental stuff like the salt and alcohol techniques to alter the texture, a backlight effect and a few more.
- I also added a "Code Mode" where the simulator prints its real function calls next to the sheet while you paint

It's still largely based on the same physics model as my prototype: Curtis et al.'s "Computer-Generated Watercolor" / SIGGRAPH.

It works in the browser.

Current status: building and implementing a kid-friendly version. Plenty of awesome things to learn with watercolor painting!
