## Описание

As there is a lot of progress in simulating the motion of fluids, and paint is a fluid, then why not simulate the process of painting on a canvas? The simulations with this technique are so detailed that even the bristle interactions are taken into consideration, therefore one can capture artistic brush stroke effects like stabbing. Traditional techniques cannot even come close to simulating such sophisticated effects.

### Segment 1 (00:00 - 02:00) []

Dear Fellow Scholars, this is Two Minute Papers with Károly Zsolnai-Fehér. Some people say that the most boring thing is watching paint dry. They have clearly not seen this amazing research work, that makes it possible to simulate the entire process of painting on a canvas. We have covered plenty of papers in fluid simulations, and this is no exception - I admit that I am completely addicted and just can't help it. Maybe I should seek professional assistance. So, as there is a lot of progress in simulating the motion of fluids, and paint is a fluid, then why not simulate the process of painting on a canvas? The simulations with this technique are so detailed that even the bristle interactions are taken into consideration, therefore one can capture artistic brush stroke effects like stabbing. Stabbing, despite the horrifying name, basically means shoving the brush into the canvas and rotating it around to get cool effect. The fluid simulation part includes paint adhesion and is so detailed that it can capture the well-known impasto style where paint is applied to the canvas in such large chunks, they are so thick that one can see all the strokes that have been made. And all this is done in real-time. Amazing results. Traditional techniques cannot even come close to simulating such sophisticated effects. As it happened many times before in computer graphics: just put such a powerful algorithm into the hands of great artists and enjoy the majestic creations they give birth to. Thanks for watching and for your generous support, and I'll see you next time!
