Eastern Ink Painting on a Computer
Roland Piquepaille writes "Traditional Oriental ink painting is more easily done with real brushes than with a computer program because you need to model how the ink is flowing into an absorbent surface such as paper. In this brief article, Technology Research News writes that "researchers from the Hong Kong University of Science and Technology have developed a brush-and-ink-style paint program, dubbed MoXi, that uses a model of pigment particles in water flowing into paper." These virtual Chinese brushes simulate in real time the ink dispersion and could be available on your PC within two years. This longer overview contains more details and references. It also includes pictures generated with MoXi. Finally, it looks at a potential trademark problem over the name MoXi."
Try Corel Painter. Unsurpassed natural media painting program... lots of great Photoshop & Painter graphics here. Painter supports brush plugins, I wonder if MoXi will be released as one...
No encryption can withstand the power of the Lucky Guess.
Almost forgot Artrage, a free natural media painting program for Windows and Mac OS X. Definately worth a look.

Atleast its better than his "brain-not-like-computers" story from a couple of days ago.
Ill advertise this cool greasemonkey script again for those who always feel dirty after they land on primidi.com : De-Piquepaille Slashdot
How about a passive-agressive protest, where this script is extended to not only ignore the story, but automatically post an "I've boycotted this Roland Piquepaille advert"
Sorry, no, thats being a tad stupid. Its just been SUCH a boring news day...
prostoalex leads the /. hall of fame.
prostoalex has the higher number of posts and owns a blog. If you just here for whinning go elsewhere.
I thought its been a part of Photoshop since version 6, IIRC? Here is just a quote from a SAM's PHOTOSHOP guide on the Sumi-e filter. There is also a filter in GIMP. My camcorder also had a Sumi-e filter built into it, but it tends to smear the image too much resulting in loss of texture quality and improved image compression storage.
without prejudice
Besides Fractal Design, there are a whole lot of other patents which they'll have to dodge such as " 6,906,70 Electronic module for sensing pen motion" (Microsoft 2001), " 6,801,211 Computer painting system with passive paint brush stylus" (Forsline et al 2001), " Brush stroke palette feedback method for automatic digital \"painting\" effects" ( Silverbrook 1998), "5,432,896 Watercolor simulation in computer graphics " (AXA 1991), and "5,155,813 Computer apparatus for brush styled writing" (Wang Labs 1991).
Input devices and lots of other hardware projects are a pain to produce independently because of all these patents. So despite the low cost of actual materials (transducers, chips, etc), it's hard to start a small, creative hardware business because of licensing costs and other legal overhead.
Here is some general information about MoXi provided by Technology Research News.
Below are two images generated with MoXi, the first one being called "Lotus leaves" and the second one "Planet" (Credit: Hong Kong University of Science & Technology)
Here are two links to larger versions of these images, the "Lotus leaves" (1.30 MB) and the "Planet" (1.47 MB).
The researchers behind the MoXi project are Chiew-Lan Tai, Associate Professor at the Department of Computer Science, and Nelson Siu-Hang Chu, her Research Assistant.
For more information about their projects, you can read these two pages about the Virtual Chinese Brush and about MoXi. On this page, you'll have access to several videos and images. The two pictures above come from this page.
The MoXi project will be presented at SIGGRAPH 2005 under the name "MoXi: Real-Time Ink Dispersion in Absorbent Paper." Here is a link to the paper submitted by the researchers (PDF format, 1 page, 145 KB). Here are an excerpt from the introduction.
According to the researchers, this technique "could be used practically in one or two years." But is this possible that this technology can be sold under the name MoXi? There already is a Digeo service named Moxi which offers High Definition TV (HDTV). And Digeo claims in its press releases (check this one for example) that Moxi is one of its registered trademarks.
Just to amend your post a little...
Fractal Design's Painter and Expression were later marketed under the MetaCreations brand. They dissolved and put their products up for sale.
Expression was bought up by Creature House, which Microsoft bought.
Painter, however, was bought up by Corel; http://www.corel.com/painterix/home/index.html
Painter has the tech that's much more like what's being referred to in the article.
Expression is much more a vector brush strokes/etc. thingy which is quite cool.. and v3 is available from MS for free.
And please quite perpetuating that Expression is trying to 'be like Photoshop'. It's not. It's an entirely different piece of software.
There is a freely available thesis on the simulation of Chinese brushes titled The Parametric Hairy Brush.
There's some guy named "Roland de Pipuequaville" or something. I can't spell his name. Apparently the slashdot editors have been linking his website a lot for some months. There's this bizarrely large clique of users who are so absolutely blinded with hate and envy as a result that they apparently just absolutely can't stand to talk about anything else.
Thats a great explanation, except for no. People do not like Roland for the following reasons :
A) his website
B) his website
C) his website
Check the article he submitted.. particularly, the "This longer overview" link. Guess where it goes? Why, his own website/blog chock full of hit ads, ads, and even more ads to generate "hit" revenue from slashdot. You even going to his site just made that douchebag some money, and the guy is capitalizing off of submitting stories to slashdot.
What if you ran a small news site that came up with a steady stream of stories, and some guy plagerises 100% of it, mirrors it on his own site and collects all of the advertisement revenue that supposed to keep YOUR site alive? Wouldn't you be a little pissed off? Yeah, I would too. Welcome to what he's been doing on slashdot for quite some time.
Get your facts straight before you come to these conclusions about all the "roland haters", k? Thanks.
There's about two decades of prior work in this field. I've always found the non-photorealistic rendering papers at Siggraph to be particularly interesting and creative. Chinese and Japanese painting are a rich area of study since they are well suited for physical simulation and offer a significant challenge.
The paper that started things off was "Hairy Brushes" by Steve Strassmann at Siggraph '86. I haven't seen this paper in a long time and I can't find it online.
One oft cited work, perhaps the first to look specifically at Japanese painting in computer graphics, is Guo and Kunii, "Modeling the diffuse paintings of 'sumie'", 1991. I can't find a copy of this either.
A more recent paper is "Two Methods for Creating Chinese Painting" by Chan, Akleman and Chen. Available online here. In addition, this paper has a good summary of previous research in the field.
One of my favorites is Barbara Meier, "Painterly Rendering for Animation", from Siggraph '96. It's devoted more to European painting styles but it is a great paper. Found here.
