This is very cool. One thing that I think could be improved: It looks like the model is treating the white background as if it is also paint. This leads to some weird results when painting over existing strokes.

Really awesome work though.

20 seconds of drawing with default parameters and laptop temperature went from 40 to 70 °C. Not bad :D.

Nice work though, very beautiful and realistic.

Holy moly! Awesome work. It looks very realistic. Congrats!

His other work is cool too: http://david.li/

the green Vortex Spheres maxed out my gtx 1070 what the heck

It appears to be some sort of fluid simulation.

Tried to open it on my Chromebook. Ouch.

Outright crashed my firefox :) Seems to be very demanding.

I have a 1080 and didn't even turn on the fans. Something is wrong.

This is a great share. The Fourier example is a great way teach about Fourier series and decomposition. Very cool!

Amazing how well it handles painting on top of previous strokes.

Amazing. It seems like it'd be really useful to be able to zoom in and out as well.

Doesn't have dark colors. The darkest paint is brown.

the box in the middle of the color picker is saturation and lightness, drag towards the left on the top of the box to reduce the brightness downward.

The darkest color comes out as brown for all colors though.

You're right... I hadn't tried black.

This seems obvious but somehow I never considered that you need three dimensions to replicate the feel of most paints.

If you are accustomed to seeing prints and photos and computer scans, it's easy to overlook how oil paint is like a sculpture. Watercolor, not so much.

Pretty cool. Next step is mixing colors and different thicknesses like real oil :)

This reminds me of Bob Ross and his "Happy Little Trees". I think I could paint some on here if the canvas were bigger, and there was an area off to the side to mix the paint.

Fantastic. One criticism. On click please make the paint "dip" and paint, and the paint on the brush should wear out. Then it'll really feel like painting. Click again is to re-dip in the color of choosing.

This will even let for mixing of colors like on a painter's palette.

:) Very nice tool.

To "really feel like painting" for me it would have to simulate spending hours with blue tape, spilling on my shoes, making multiple trips to home depot... sounds like a job for VR... ;)

You can compare this to what I believe is the state of the art system, "Wetbrush":

Of commercial applications, Corel Painter remains the professional natural media paint tool:

It's been around for about 25 years and some of the UI is a bit creaky, but on the upside, it's pretty fast on modern desktops and it still gets regular updates. Brush strokes with 3D depth ("impasto") were introduced a long time ago, maybe late '90s.

This is too slow to use on my MacBook... I like the idea though, and it seems really cool.

My MacBook Pro sounds like it's taking off a runway :P

This is great for calligraphy with surface pen - can't find the black ink though.
Jordrok
Very cool!

Man, does it peg the hell out of the CPU though! :P

It was hogging about 60% of one CPU core (Skylake i7) on my PC. Seems like it's re-drawing the screen at 60 fps even though nothing is happening. Should be an easy fix.

so cool, consider adding an option to remove paint from the brush so you can scumble the fluid to blend.
