We  were lucky enough to have a chance to present a gift to Dr. Jensen Huang while he was in Hong Kong.  The gift is a piece of calligraphy hand-written with Expresii by our Dr. Nelson Chu.   The text written is a poem made with the help of ChatGPT AI. The following is a video documenting its making.

On 23 November 2024, Jensen Huang received an honorary doctorate   in engineering from the Hong Kong University of Science and Technology (HKUST). Dr. Chu  was honored to    present the gift to Dr. Huang on the same day.   Both Dr. Huang and Dr. Chu are now fellow HKUST alumni.​   ^_^    

The first characters of each verse are from the Chinese names of Jensen Huang (仁勲) and Nvidia (輝達). Here is a  short  English   explanation of the text:

仁芯拓算力: Jensen’s chips (pun ‘kind heart’) expands computing power.
勲業領風流: Nvidia (‘distinguished work’) leading the way.
輝影繪千變: Computer imagery transforms. 
達智創新猷: Reaching intelligence, creating new strategies.

The stamp ‘墨戲’ (MoXi) on the upper right of the piece  was from a physical seal and is the name of the software prototype Dr. Chu made at HKUST.   The  sundial on the lower left was painted by Dr. Chu digitally while he was at HKUST around 2006 using the MoXi prototype. 

Calligraphy is a highly regarded art form in East-Asian cultures.   In late 90's, Dr. Chu set off to create a virtual brush system for digital calligraphy  & painting.  That was also the dawn of modern GPU computing - in early 2000's, Nvidia made the first GPU with programmable shading, together with  software components like the Cg language,   that can be used for general purposes including fluid simulation.  With the help of the latest GPU technology, Dr. Chu was able to unveil a software   prototype   featuring a virtual brush   in 2002 and present the MoXi prototype  featuring both virtual brush and virtual ink at SIGGRAPH 2005.   You can say it was Dr. Huang's company that made Dr. Chu's dream come true!   Dr. Chu's   MoXi research paper   was also the first all-local-effort SIGGRAPH paper attributed to HKUST and Hong Kong.  

We thank the HKUST management for allowing such a gift presentation to happen. The smile on Jensen's face was priceless! We also thank Helen, Vv, Wilson Yuen and Tiffany Tang for their support!

We took part in the Hong Kong Illustration and Creative Show 2024 Spring, giving  some talk or demonstrattion at the CGLive booth.  During his talk, our Dr. Nelson Chu showed a little sneak peak of what he's working on for simulating Western watercolor. 

​​We are lucky to have Sensei Shuen to give a demonstration at the booth.  You can learn a lot from her on ink painting and the use of Expresii:

This piece "劔舞乾坤" (sword dance) is spirited.  The subject's pose, the composition, the linework, the contrast all contributed to the energetic look of it. Find out how it's done in the above video!

And here's the calligraphy our Dr. Nelson Chu did  as inscription for the painting:

The all new WACOM Movink was on pre-oder at the show. It's among the few places  where you can try the new hardware first hand. Pretty good price at HKD5889 there (compared to the offcial price in another region next to Hong Kong)! It's really thin and light.

We have invited  Sensei Shuen  to demo ink painting  at the Hong Kong Illustration and Creative Show on 26 June 2023. Listen to Sensei   Shuen  (in Cantonese, with English subtitle) as she paints, with tips in using Expresii and WACOM hardware:

Thanks for visiting!  Hopefully more people are aware of our invention and effort in digital painting development.

The spec of Windows machine used for the demo:

Basically, you need a good GPU  (graphics card) to run Expresii smoothly.  e.g. an nvidia 1060 with 6GB vRAM is good for running Expresii smoothly on a 4K monitor. If you're only using a full-HD monitor, you can go by with modern integrated  GPU like Intel Iris Xe. For example, the Microsoft Surface Pro 7 (i7) or 8 (i5) can already run Expresii smoothly on their own 2.5k monitor.

We thank CGLive and Wacom Hong Kong for their support!

I was told that recently Japanese calligraphy, or just Japanese culture in general, is much appreciated in Germany   and Wacom has been showing Expresii for calligraphy in their German Experience Center in the past few months in events like "Night of Museums", or "Japan Day":

Wacom official artist Miki Amano is also showing the public the use of Expresii with Wacom tablets for digital calligraphy, with   sample works   including their official tagline written in Chinese. 

In China, calligraphy has been the basic training for painting - it lets the artist acquire the dexterity for controlling the brush.   Also, calligraphy is inherently an abstract art form.  Arguably, cursive calligraphy is considered the highest form of art in China. No wonder why Pablo Picasso said "Had I Been Born Chinese, I Would Have Been A Calligrapher, Not A Painter."

Earlier this month we were invited to visit NTU, Singapore.   Our Dr. Nelson Chu gave a talk titled "The Quest for Digital Ink: developing tools for Painting, Calligraphy & Animation"  (Abstract & Bio) on 20th Sept 2019, jointly organised by the School of Computer Science & Engineering, the   Alibaba-NTU Joint Research Institute, and the  NTU-UBC LILY Center. Dr. Chu shared his journey developing digital brush and paint dating back to 1999.  We also met with folks from Cacani the animation system.

We also took the chance to visit the Singapore Zoo,  and  used Expresii on a 2017 Surface Pro  to do some sketch  there:

We miss the food there already.  （*´▽｀*） We look forward to visiting Singapore again!

Expresii is being used for producing the animated feature film  Red Squirrel Mai 紅松鼠米高. Do check out    the teaser above (those from China can see it  here)!  This film uses Expresii extensively - both animation background and foreground  are drawn with Expresii.   The teaser video is shown at Hong Kong Filmart 2019 earlier this month.   We thank   Ink Culture Ltd and Rooftop Animation for producing such a meaningful work - this animation is the first one made in Hongkong/China that has a distinct style different from all previous works.   It's been only less than two years from the setting up studios in Hong Kong and GuangZhou.   

Ink wash animation  is a  proud product of China from the 60's to the 80's. Nowadays,   many attempts have been made to modernize ink wash animation.   Our Expresii does provide a refreshing visual style that couldn't be achieved before.

One of the film Directors of Red Squirrel Mai   Angela Wong draw Mai the squirrel, the movie  protagonist,    on the spot:

Our Nelson demonstrates calligraphy in the show:

And also some doodles (after the  famous comic artist 草日 from Hong Kong):

An inkjet printer was also setup there to print artwork done with Expresii on the spot:

We're lucky to encounter Kumamon as our Mai just stepped out of our booth: ^_^

 P.S. Now you know why we have to put up a notice forbidding new users to use Expresii for making feature films till later in 2019.   ^_^

 Hong Kong-based artist Shuen Leung   tries out Microsoft Surface Studio and Surface Book 2:

Shuen does artwork in both traditional and digital media.  She specially likes Expresii for its ability to undo.   "Expresii 是可以undo 的 水墨!"     (ﾉ´ヮ´)ﾉ*:･ﾟ✧

Check out her website and Facebook page for  works, art tips and more.

We ended last year with SIGGRAPH Asia 2016 held in Macau.  Little did we know it was a great start of an amazing year ahead.   For Expresii, there are mainly two major themes  in 2017: 1. Animation. 2. Microsoft.

Soon after SIGGRAPH Asia,  Angela Wong  took Expresii for a spin and made some simple yet impressive animations like  the Red squirrel  and the  Swallows ​. I think the Red squirrel  now becomes a classic sample for modern ink animation. A Japanese anime studio has been using Expresii for background paintings for some TV series but now Expresii is used even for foreground animation!       o͡͡͡͡͡͡͡͡͡͡͡͡͡͡╮(^ ਊ ^)╭o͡͡͡͡͡͡͡͡͡͡͡͡͡͡​

   'Ink Animation' (or 'Brush Painting Animation' or 水墨動畫 in Chinese)  was a proud product of China from the 60's-80's but there  wasn't much new development since then.  There have been attempts to do ink animation  using existing fluid simulation in 3D CG software packages but they mostly created something that look like fume (e.g. this) instead of Eastern ink painting.  Another popular way was to map captured real brush strokes textures and map them onto 2D or 3D geometry (e.g. those made with LivingCels) - which could make the animation look like  shadow play  where you see fixed textures shifting around. In 2017 summer,    Shanghai Animation Film Studio     (上海美影廠)   unveiled  a new title 《斑​羚飛渡》(youtube)    and gave a talk on the their new development on ink animation. However, what they claimed to be breakthroughs (building a library of stroke forms and combining 2D with 3D) aren't really breakthroughs.  

Now with Expresii we hope to develop a truly modern way of doing ink animation.   We are still experimenting and will unveil what we come up with when ready. 

We started to get attention from Microsoft near the end of last year. Once we got in contact with the right personnel  things happened pretty quickly. In April we secretly flew to Redmond to meet with Microsoft technical folks and management including Corporate Vice President of Microsoft Devices, Panos Panay, who was impressed by our Expresii. ​​Our saying 'every stroke has its own personality' struck him. He specifically asked to have our app ported to their App Store and we did . Panos asked why don't they  hire this guy (i.e. our tech guru Nelson Chu). And he was told  that Nelson did join Microsoft several years back and he was actually a key contributor to   Project Gustav, which later became Fresh Paint   - which Panos himself still uses to show their hardware. ​Within our short trip,   we were filmed in Seattle for a Microsoft partner video (by Watts, see their page  for a longer version of the video):

All these were in preparation for the then-top-secret global launch of the New Surface Pro in May.  It's our honor that Panos decided to talk about Expresii on stage himself.  We were also invited to local launches in Hong Kong  and Taiwan.  Later Microsoft also features Expresii on their Surface Pen page  as well as their 'Apps for Windows Ink' collection.  

We are especially proud to be the only team from Asia to be featured in Microsoft's 2017   app partner collage video.  In fact, when we cut out the parts, we are surprised that Expresii bits  total 30 seconds, or 1/4 of the  2-min. collage's length!  And notice that the other app partners include giants like Adobe, Autodesk & Corel.   

In Expresii, not only are we able to develop advanced software technology that even giant competitors can't make, we are also promoting the good side of our culture through technology. Expresii is not a me-too app. We have our own visions and we try our best to implement them even given limited resources.

Expresii  is being developed as a painting app and we didn't expect it to be used more and more  in animation.   ​It was even  used in this 2017 TED-ed  Animation .  We may be a bit quiet lately but we are far from being lazy. We just can't wait to show you new stuffs when they are ready. We are really grateful to our partners and friends for making things happen. We  look forward to more industry   collaboration and new possibilities in 2018!           (ﾉ´ヮ´)ﾉ*:･ﾟ✧

We thank Mark Lam of CGVisual.com  for introducing us in the session 'CG in China' at  SIGGRAPH ASIA 2017, held last month in Bangkok, Thailand.

Our new  ink pusher tool was shown to public  for the first time during   the session.   Here is the video again:

As you can see, you  get  just-right amount of control and things stay like water-based paint with details. 

We can't wait to try it on big devices like the Surface Studio.   ​Ψ( ﾟ∀ﾟ)Ψ

Earlier this month, our Dr. Nelson Chu, along with  two more  alumni ​, was invited to speak in an alumni sharing session by HKUST.   You can review the whole sharing  here.   Nelson showed our  ground-breaking app Expresii on a tablet computer to the audience.   

During the Q&A section, Nelson was asked   to comment on how to deal with people saying digital art is not real art. To answer  this, let's first assume people don't regard digital art as real art because they think operations like undo and redo   mean   cheating. Let's here what Nelson has to say:

'Long time ago when the Western fountain pen got introduced to the East, people might say "pen calligraphy" is not calligraphy. Only brush calligraphy is. But now people accept that pen calligraphy is also calligraphy' said Nelson.

Nelson is a firm believer of digital calligraphy.  See how he does digital calligraphy with his own tool Expresii: 

From the above videos, you see how undo's and redo's allowed more flexibility and save time  to create the perfect design without wasting paper.    ​(^(エ)^)

In deed, if you look at the history of writing tools in East Asia, you will see we keep adding new tools to our arsenal over the years.  If we insist that a new tool has to act exactly like what came before it, there wouldn't have been brush calligraphy in the first place because we would still be using carving knifes to write. 

​​We should really   embrace new technology   and   explore what we can do with it.

Another possible reason why people don't consider digital art real  is that they can't sell it to galleries or collectors like they do with works done in physical media.  People are concerned that artists  (along with a whole ecosystem of art dealers) can not make a living if there are no   originals  (vs. digital copies) to sell.   

To respond to this, firstly, we'd like to emphasis that artistic value is NOT market value. If we stick to the question of  whether something is real art we should  really judge it by its artistic value.   Whether it sells or not is a completely different story.   For a painting, we judge its artistic value by e.g. the use of colors or  composition, which you can also find in digital art. 

Secondly, business models can adapt to changes.  A century ago, musicians made a living by performing live. With the invention of sound recorder, musicians don't lose their job simply   because there is  a way to playback their music. Instead, a whole ecosystem of record companies & distributors came into existence. And then came the digital age, when people don't buy CD's as often.  Record companies could blame digital music making it easy to be pirated. Then Apple fights the problem by providing a way to get legit music easier than looking for pirated copies.   And if you think those big companies are paying artists  too little royalty ,  now independent   artists can sell their music, art or tutorials via sites like Gumroad with a much bigger cut,  effectively  democratizing  art selling for creators.
