Expresii is officially launched!! (ﾉ´ヮ´)ﾉ*:･ﾟ✧
It's been a long time. When MoXi was first unveiled in 2005, I was asked how soon it could become an actual product. I answered, 'could be two years'. In 2006, MoXi was licensed to Adobe, and I was even hired to do tech transfer. I was hoping MoXi would have good future there, but the story didn't evolve as I thought.
Anyway, if they can't make it happen, we will.
I know we all love free software but sorry that we need to start charging for the tool now (introductory price US$59), since it took a lot of time and effort to create a tool with such advanced algorithms. I think this is the most direct and healthy way for Expresii to grow without going down the path of showing ads or telling you it's free but then charging you in some funny way. Your financial support would determine if small guys like us can survive or if we are left with tools coming from big companies only .
- Yibi Brush Engine - giving you power to create organic shapes like wielding a real brush
- Moxi Paint Engine - with fluid dynamics bringing water-based paint sim to a whole new level
- Youji Rendering Engine - allowing ultra-deep zoom with hybrid vector-raster representation
Expresii is a successor of MoXi developed by Nelson Chu over the past four years with improved simulation and rendering. Expresii for Windows is now offered at an introductory price of $59 with trial license key available.
Notes to Users/Reviewers
- Expresii currently focuses on mimicking Eastern ink painting/calligraphy only.
- Eastern ink is similar to but not exactly like Western watercolor. e.g. a drop of watery paint on most Eastern painting paper s would absorbed and spread out immediately; on Western watercolor paper the drop would just sit there without spreading.
- Paint with a Gradient - In contrast to traditional paint apps, picking up of colors in Expresii is pressure-sensitive. The harder you press, the color goes more into the tuft. This way, you can get a multi-color loading similar to how you do it in real-life Eastern ink painting. Expand your skill set by learning to use the side of the brush to paint with a gradient instead of one color at a time.
- Economy of Strokes - Try to reduce the number of strokes you make. More for less. In Expresii, we make it possible to appreciate even one individual stroke.
- Rhythm is Everything - in some paint apps, you may be stamping scanned bitmaps of real strokes. At an extreme, this is close to how a designer works where you position design elements to form a composition . In Expresii, we want to promote another way of painting - one that is almost a record of the movement of the brush driven by your hand. It's gestural. It's more like a serendipity where you can't create the exact same thing twice.
- Choice and Chance - You make some strokes and let the wet ink do its thing. It's not just simple put-that-color-there thing. The ink reacts to your action and could inspire your next stroke.
- Limited layers - Currently Expresii only supports two layers. We'll support for more layers in the future. In the meantime, the Snap-Down (rasterizing) to Underlay acts as a temporary solution when you run out of layers. Given only two layers, we usually do linework on one, and color/fills on the other.
We use Computational Fluid Dynamics for our ink flow simulation to give you the most natural results.
We use a novel hybrid-vector-raster representation to allow high degree of zooming in.
感謝【狐朦大叔】作者Tom 一直支持。他也剛出書了（用Expresii 畫），感覺是一起生了小孩。還有感謝一直支持的Shuen Leung, Mark Lam, 日本的 Kuroda-san ，和盧生、李生和最近認識的飯主等前輩的經驗分享和幫忙，還有Wacom 台灣總經理Martin的推介和其他高層的賞識，和其他曾經給予鼓勵支持的朋友。
2002年去北京發表虛擬毛筆的論文，時年二十五當是個交代。現在趕在四十歲前把Expresii 推出了，也算是個交代。我的青春都放在這電腦繪畫的研發了。 作為一個東方人，我覺得有責任去把我們最好的東西，承傳並發展下去。筆有千秋業！
