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 recently added  native support for Microsoft Surface Dial.   The combination of   pen, touch and wheel gives you a new way to interact with Expresii.

Two custom menu items,   Rotate & Brush , are added specific for Expresii: 

When Expresii's main window is in focus, a press-and-hold on the Dial takes you to the above radial menu.  When Brush is selected, you can press the Dial to invoke our own Brush Control Menu, which has  four items, namely Brush Size, Loading, Wetness and Scratchiness:

For instance, you can use the Dial to adjust Brush Wetness while you stroke:

All of these controls, except brush size, can be adjusted as you stroke.  Yes,  as you stroke, instead of between strokes. Things  happen in real time.   You can rotate the paper with the Dial as you paint. By adjusting your pen tilt angle at the same time, thanks to the tilt-sensitivity of the pen, you can create  interesting patterns!    

When you enable gravity  in Expresii, your rotation actually  directs the ink flow. Expresii's advanced paint engine  give the most natural simulation of brush and ink hands down. You won't believe what your Surface device can do!

And of course the Dial is also handy for undo and redo. See it in action for yourself:

We had a lot of fun playing with   Expresii   &   the dial.   We hope you do too! ​As always, stay creative!    └(°ᴥ°)┘​

Lunar new year day was  16th of Feb, 2018.   We wish you all the best for the new year  of the dog!

Now it's being a tradition we play with the Chinese character for the year.  This year, we play with the character 狗, which means dog:

Recently, ambigram  is popular around East Asia, so we make one that reads dog and shows a dog 90-deg turned.  

​And notice how we use pen tilt to make organic marks.

Chinese characters give you so much room for imagination!  We can't stop playing with them!
​大家快來寫數位書法，漢字給你太多想像了！

Only Expresii gives you this level of expression with brush and ink! 

Soon after the Nintendo Switch was released in March 2017, digital artists have been using the controllers, called Joycons, as a hand-held controller for digital painting.  In contrast with all previous low-cost single-hand game controllers we tried before, the joycons ($80 a pair ) are equipped with gyroscopes, accelerometers and even IR motion camera.   ​

The joycons works on Windows even without installing a driver  but the analog thumb-stick only works as digital buttons.  Thanks to  this   Joycon driver for Windows   by Matthew Fosse, we can now also use the analog joystick (and maybe later the gyroscope too).

After installing vJoy and Joycon driver as instructed by the Joycon driver page, we are able to use Joycon for quick controls for Expresii. We had to connect the Left joycon instead of having left and right combined, since the mapping of the combined controls is different from what Expresii currently accepts. We tried  x360ce  to remap the controls but  we didn't figure out how yet. :)   Currently, Joycon driver outputs gyroscope data as rotational impulses rather than tilt angles so we can't really make use of the gyroscope  for brush tilt yet.   Anyway, here is a short video of using Joycon with Expresii:

We thank Mandy Ng of   Rooftop Animation    for providing the Joycons. ​

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 - which could make the animation look like Chinese 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 《斑鹿飛渡》 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✧

This is mainly    for those from China only.  If you're from other parts of the world please just buy directly from Gumroad or Win10 Store.

好消息，现在Expresii已经开始支持微信支付，支付宝，银联等购买方式。想買的可以直接這個鏈接購買Expresii 的 Win32版，但先請確定你能用且用的開心才好買啊，因為退款比較麻煩  :P    謝謝支持！

進入Avangate 的畫面是這樣的，下面有可選 微信支付，支付宝，银联等的：

買完之後，會發給你一個License Key，之後也是要用‘防火牆模式’註冊的啊。
​
如果您的機器，有較好的GPU，跑Expresii 是通常都有100+FPS（在視窗頂的title bar 可以看到FPS），那就應該會用的挺爽的（intel 的 GPU現在比較多會出些error）。

其實不用註冊也可試用，只是不能存儲而已。如果您有用Win10，也可到 Windows 10 Store (应用商店) 试用（30天，能存儲）或购买Expresii 的Store 版。

p.s. 以後不用怕淘寶代購會刷黑卡了。

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. 

Second, 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 pirate. 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 by creators.

Previously we've been trying   cheap bluetooth VR controllers    but they either don't really support Windows, or they don't offer analog joystick input (joystick only act as buttons): 

Thanks to Shuen Leung, recently   we discovered a couple of Keysco   branded  bluetooth controllers that could act as analog joysticks under Windows.   However, they could only be seen as DirectX devices so we also added support for DirectX (DX) game controllers in Expresii. These should be the cheapest single-hand controllers that offer analog input for Windows on the market now.  And they are more comfortable to hold than then R1 shown in the youtube video shown above.  If you can communicate in Chinese,  you can get one from Taobao for RMB35 (=$5.3).   Otherwise, you can buy one from   Amazon    currently at $9.8 or   Ebay  at $6.95.

Below is a process walk-through video for connecting the controller and using it in Expresii.  You can press WIN and type 'joy.cpl'  and press enter to get to the control panel  item  for game controller shown in the video.   And FYI, those Keysco controllers we tested only give 4 buttons - those shoulder buttons actually maps to one of those A B C  D buttons!  Also, the analog sticks are not very sensitive as some of the more professional ones like XBox or Plasystation controllers.

Such a controller is useful for quick access  if you don't want to use a keyboard.   In particular, if your stylus doesn't sense tilt yet, you can also use the analog stick for pen tilt, or even for painting surface tilt.

Let us know if you need more function assignment  for game controller and we will consider adding them.   ^_^

The white one on the left doesn't even connect to a Windows machine via bluetooth,  although the description says it supports PC.   The Mocute on the  right connects to Windows device, but those buttons and  thumbsticks map to number keys - not working as a game controller as expected. :(

The New Surface Pro was announced back in May this year.  Today we will show you how Expresii runs on it.

The outlook of the New Surface Pro is mostly the same as that of the Surface Pro 4, except that the more rounded edges now feels more inviting.  ​ The top model (CPU: i7 7660U; GPU: Iris Plus Graphics 640; RAM: 16GB) is capable of getting 100+ FPS. I'm very pleased with the performance given  the sleek package of the Surface Pro.   See a demo video   below - which include spontaneous painting  of some eggplants:    ​(ﾉ･д･)ﾉ

Highlights of the new Surface pen over the last generation:

1. Tilt sensitivity
2. Much lighter activation force
3. Much reduced lag,  especially near device   edges

The only downside  is that it doesn't support tilt sensing while hovering, something we normally would get  with Wacom's EMR pen   on their Intuos Pro or Cintiq lines.  Disappointingly, those new 2017-released  tablets equipped with Wacom's EMR pen technology (namely Samsung Galaxy Book &   Acer Switch 7 Black Edition) do not support tilt sensing during hover as well.      (๑◕︵◕๑)

Without hover   tilt sensing, you don't see your virtual brush in the right orientation right before you stroke.   That'd be awkward  because you need to know how the brush is touching the paper to make a mark.   Fortunately,   brush orientation   left from the previous stroke doesn't affect the correct rendering   of a new   stroke  with an initial tilt angle   quite different from   the final tilt angle of the previous stroke.  

In most advertisements by both Apple and Microsoft, they would say 'tilt to shade'.   Here, we show you that tilt is  not just for shading, but also for making   organic marks using the side of the   brush   as well.   In Expresii,  your ink and   brush  really interact with the paper. 

A lot of people  think the new pen is more sensitive because of the pressure level increase.   To me, pressure level doesn't really make a noticeable difference (given >= 1024).  It is mainly the improved   activation force   that makes the new pen feels more sensitive.  Those who are not sure about this   can try    toggling the   '1024-level'   option    on your Wacom device and see if you notice any difference.  ​

Yes, you're covered.  ​According to Microsoft representative:​

"The new Surface Pen works with these generations of Surface Devices: Surface 3, Surface Pro 3, Surface Pro 4, Surface Book, Surface Studio and Surface Laptop.  The new Surface Pro is the first Surface to enable 4096 levels  of   Pressure Sensitivity  and  Pen Tilt.  These features will be updated on Surface Book and Surface Studio with updates in early 2018.  All devices benefit from the 9g-low activation force."

To make sure you get the best performance,   you can opt to use Game  Mode for Expresii.  What the Game Mode does is to    minimize background activities to give way for the foreground program.

The Game Mode is available if you have the Windows 10 Creator's Update. Press WIN+G   to bring up the Game Bar  UI. Read more about the   Game Mode   here .

I'm impressed by what Microsoft has achieved over the years for the Surface Pro Family.   I wish in the near future they are able to support hover tilt sensing as well. Expresii really shows off the sleek new Surface Pro for its powerful GPU and its new pen.   Users can make vastly different organic marks  simply by varying pen pressure and tilt angle, as well as the wetness of the virtual brush.  This allows spontaneous painting  not possible in any other app.
