Current Work

Craftica is a creative sandbox game with ultra high degrees of freedom for building. It supports multiscale subvoxels so that smoother objects can be built in more realistic scales, and makes it possible to build very architectures. Craftica also provides a large number of electronic and mechanical as well as other related device items, allowing players to build sophisticated circuits and circuit-controlled electronic and mechanical devices. Players can even build vehicles, aircrafts, robots and computers etc. high-tech objects from items as basic as logical gates. Homepage: http://craftica.net |
Craftica was started as a small prototype to create a subvoxel-based virtual sandbox environment that could hopefully be useful for other projects. Though the result turned out quite positive, it took me a few months to finally decide to further develop this prototype into a actual game. The prototype was initially developed in the Dao programming language, it was then switched to use C++ for efficiency. This is my first time to develop a game, and so far I am still the sole developer for this game. To speedup development and compensate my poor skills in 2D graphic design and 3D modelling, I tried to solve most problems by programming. So, in addition to terrain generation, many things in the game (such as models, icons and placement rules etc. for the standard items) have been generated programmatically.
Craftica is now available on Steam as Early Access:

匠造奇境(Craftica) 是一款具有超高自由度的建造类沙盒游戏。它支持多尺度的亚体素，方便玩家以更真实的比例建造更平滑的物体和更优美的建筑。《匠造奇境》还提供了一系列电子和机械以及其他相关的设备器件物品，支持玩家在游戏里设计建造复杂的电路，以及由电路控制的电子与机械装置。玩家甚至可以从逻辑门等基本原件组装制造出诸如汽车、飞行器、机器人和电脑等高科技物品。 |
《匠造奇境》的最初原型来自于我的一个基于亚体素构建虚拟沙盒环境的小尝试。 尽管尝试的结果还不错，我也过了几个月才决定将原型进一步开发成一款游戏。 《匠造奇境》的原型最初是用道语言开发的，后来为了效率便改用C++开发。 这是我第一次开发游戏，而且到目前为止，这款游戏还是由我一个人开发。 由于我欠缺美工和3D建模方面的经验，同时也为了提高开发效率， 游戏除了地形完全由算法生成外，标准物品的模型和图标等也都通过编程由程序自动生成。 此游戏在2021年以前曾用《开物天工》作为中文名，后改为《匠造奇境》这个更方便记忆并有更好的识辨度的名字。
现在这款游戏可从Steam下载：

I am from the Hunan Province of China. I studied Mathematics at Fudan University (Shanghai) in 1996. Then I studied Physics in graduate school for about one year also in Fudan before going to ICTP (Trieste, Italy) to study in a multidisciplinary master program in 2001. Two years later, I went to the University of Turin (Italy) for my PhD study, and worked in a lab located in its cancer research center.
After PhD study, I worked for about one year and half at the ISI Foundation (Turin, Italy), then I moved to University of California, San Diego in 2009. Since 2015, I joined Research Center for High performance Computing as an associate professor at Shenzhen Institutes of Advanced Technology (SIAT). Then I left SIAT at the end of 2016 and founded a startup.
我来自中国湖南。 我本科就读于上海复旦大学数学系（96级）。 研究生期间在复旦读了一年物理硕士，然后去了在意大利Trieste的 ICTP（国际理论物理研究中心，下属联合国教科文组织） 参加一个跨学科的硕士课程(2001)。 两年后又去了意大利都灵大学读博士(2003)， 并在下属都灵大学的肿瘤研究治疗中心做生物信息方面的研究。
2007年底博士毕业后我在都灵ISI Foundation做一年半研究。 之后于2009年去了加州大学圣地亚哥分校做博士后研究。 从2015开始，我作为副研究员加入到了中国科学院深圳先进技术研究院(SIAT)的 高性能计算技术研究中心。 2016年年底，我离开SIAT开始创业。
Software Projects:
Programming has been an integrated part of my work (and my hobby:)) since graduate school,
so over the years, I have created a number of open source projects.
Most of them are related to Dao, but in attempt to create various
modules and bindings for Dao, I managed to expand the projects to
touch various types of libraries and applications.
Current

CD-HIT - DNA/Protein Sequence Clustering Program
CD-HIT is a popular program for clustering DNA/protein sequences originally developed by Dr. Weizhong Li. It implements a greedy algorithm to cluster sequences incrementally and efficiently. I toke over the development in 2009 and rewrote most parts, in addition, I developed a novel parallelization technique that can speedup the clustering algorithm almost linearly on multi-core machines.

软件项目:
从研究生阶段开始，我的学习和工作（以及主要爱好）就和编程密不可分。
因此，这些年来，我创建了不少开源项目。
其中最大的是Dao程序语言开发项目，其它项目也大都和Dao程序语言相关，
目标是建立一套Dao语言能使用的模块和工具。
这些项目的开发过程，使得我有机会涉猎不少不同的领域及相关的库和应用程序。
