The app was selected for 2012 ACM SIGGRAPH. SIGGRAPH Conference on August 8 for the app made a special Damo display, is the first Chinese local creative team and development team to use mobile platform combined with three-dimensional animation, information technology to promote the traditional Chinese kungfu culture success.</p></p><p><p></p></p><p><p></p></p><p><p>Team</p></p><p><p></p></p><p><p><strong>Selected Topic lock Kung Fu Collection Taiji Master action data</strong></p></p><p><p></p></p><p><p>With the increasing popularity of smartphones and tablets, more and more people want to get information through mobile devices, and mobile device-specific Touch-style Interaction also brings people a more intuitive operation Experience. The emergence of many interactive teaching apps, for example, reflects this trend. In Kung Fu culture, the most Chinese characteristics, while the most widely spread in the overseas when it is taijiquan, Taijiquan and Chen Taiji is the most ancient and authoritative, so the production of Chen Taiji's Mobile application has become the first choice of project Topics.</p></p><p><p></p></p><p><p></p></p><p><p>Siggraphasia Show Video</p></p><p><p></p></p><p><p>This app will capture the three-dimensional motion captured by the Tai Chi Master of the accurate data, through three-dimensional animation in the form of mobile platform, with the latest interactive technology to enhance the Learner's learning experience to compensate for the shortcomings of traditional teaching, while increasing the fun of learning and sharing, but also in the subtle transmission of traditional Chinese culture.</p></p><p><p></p></p><p><p></p></p><p><p>Chishiyuan, The teacher is collecting Movements.</p></p><p><p></p></p><p><p></p></p><p><p>Tanaki, The teacher is collecting Movements.</p></p><p><p></p></p><p><p>In order to ensure the quality of Taijiquan teaching, the project team contacted the 70-year-old "chinese Chen Taiji first person" Taiji master Tanaki teacher, The idea of the project got the strong support of Tian teacher, he personally involved in the data collection work, for you to show the Chen's Taiji flowing several complete routines. Tian Teacher's gaotu Chishiyuan teacher (now Chinese martial arts Duan seven, The national level coach, State-level social instructor), for everyone to carry out the move decomposition action Collection. With the support of two teachers, the project team collected expert action data from Chen's Taiji road, two-way, 13-style and Footwork.</p></p><p><p>Then the project team began to work on the data collation of Chen's Taijiquan. Considering the future production, the data volume will be more and more large, the project team set up an expert action database for data Management. At the same time, the three-dimensional model, material lighting, three-dimensional special effects, three-dimensional animation construction began simultaneously. According to Chen's Taiji moves, The master designer has carefully designed and produced 160 Taiji action icons, incorporating traditional cultural elements such as Chinese hieroglyphics, Taiji Yin and yang, into modern logo design, and incorporating the art design with Chinese characteristics for the digital Presentation.</p></p><p><p></p></p><p><p></p></p><p><p>Motioncap</p></p><p><p></p></p><p><p><strong>Step-by-Step Project Flow chart disclosure</strong></p></p><p><p></p></p><p><p>Motion Data acquisition</p></p><p><p></p></p><p><p>The patch action captures the data and converts it to a c3d file.</p></p><p><p></p></p><p><p>Using Maya and other three-dimensional production software to make three-dimensional character model, texture mapping, binding.</p></p><p><p></p></p><p><p>Import c3d files and Maya character models in the MotionBuilder software to perform action Matching.</p></p><p><p></p></p><p><p>Rewind the matched animation back to maya, and see the original action video for animation adjustment and Correction.</p></p><p><p></p></p><p><p></p></p><p><p>Taiji Action icon Manuscript design</p></p><p><p></p></p><p><p></p></p><p><p>Example of Taiji action chart</p></p><p><p></p></p><p><p>Making a scene file in Maya</p></p><p><p></p></p><p><p>Application of the overall UI design made</p></p><p><p></p></p><p><p>Editing of music and sound effects</p></p><p><p></p></p><p><p>Import the various materials that have been created, interact with the three-dimensional engine, write code, and invoke native features of iOS mobile devices such as cameras and Camcorders.</p></p><p><p></p></p><p><p>The test work of the application</p></p><p><p></p></p><p><p>Publish to Apple Store</p></p><p><p></p></p><p><p>Application of publicity and promotion</p></p><p><p></p></p><p><p></p></p><p><p>83 Style Taijiquan (click to see larger Image)</p></p><p><p><strong>Analysis of three-dimensional animation difficulties in making and developing mobile platform</strong></p></p><p><p></p></p><p><p>Model Making-control surface number adapts to mobile platform</p></p><p><p></p></p><p><p>Taking into account the preferences of various groups of people, the project team produced a total of three sets of Models. Male coach role, female trainer role and Bone point coaching role. Bone Point Coaching begins with the introduction of fun, but the simplicity of the skeleton allows the learner to see the decomposition of the action more clearly, but to a certain extent strengthens the teaching Effect.</p></p><p><p></p></p><p><p>The number of model polygons cannot be too high due to limitations on the mobile platform. Too high will make the character's action become very card, and will face the lack of device memory limitations. At the very beginning, the project team was inexperienced, so the number of polygons produced was more than 10,000. later, a variety of methods, such as the character in the course of the movement is always dressed, so the body part below the clothing is not necessary to model. In addition, the use of normal mapping technology, to ensure that in the case of Low-modulus can also achieve satisfactory results.</p></p><p><p></p></p><p><p></p></p><p><p>Brush weights for character models (click to view larger Image)</p></p><p><p></p></p><p><p>Animation Patching-correct wearing help guarantee accuracy</p></p><p><p></p></p><p><p>Due to the limitations of the collection device, some of the action in the app has appeared to wear help Phenomenon.

Most of the reasons they choose Tai Chi applications are in pursuit of health and quality of Life. So how to highlight the healthy mood, improve the convenience of teaching, and how to integrate into the teaching of fun and social is the core of our Consideration.</p></p><p><p></p></p><p><p></p></p><p><p>Video comparison</p></p><p><p></p></p><p><p>first, the interface to make users feel relaxed and healthy. After repeated revisions, the designers decided to design the interface with a return to Nature's atmosphere and Hue. In the menu icon, use the combination of graphics and text to reduce the burden of user thinking. In order to improve the convenience of teaching, in addition to allowing users 360-degree real-time viewing character animation, but also provides a video comparison Function. This makes it easy for users who are not familiar with the editing of the film to pull up their own tai Chi video, in real time with the three-dimensional role of Taiji movements. At the same time, interface designers have added some interactive design elements. In addition to clicking on the three-dimensional role can be realized in real-time dynamic change, replacement of three-dimensional coach image, teaching scenes, in order to increase interest, the application added mixed reality elements, so that users can real-time to change their true face in three-dimensional role, so that even a user who will not play Tai chi, You can also look at the way you play taiji, and then share this interesting scene with friends and Family.</p></p><p><p></p></p><p><p></p></p><p><p>Face change</p></p><p><p></p></p><p><p></p></p><p><p>Face change</p></p><p><p></p></p><p><p><strong>Art-style audiovisual design embodies taiji meaning rhyme</strong></p></p><p><p></p></p><p><p>Taijiquan virile, opposing and transforming each other. therefore, in the interface design, the pursuit of the combination of icons and scenes. The opening and closing of Taijiquan is in good agreement with the rhythm of tidal wave, which may be the embodiment of Taijiquan following the law of Nature. therefore, in this set of application of the selected, dubbing, with the guqin and the tide of the waves of the sound.</p></p><p><p></p></p><p><p>In the shape design, the pursuit of round and full shape, avoid sharp shape. For example, "My Tai Chi," The application of the 150 action modeling, imitating the Han Dynasty portrait brick round and abstract shape style, it appears simple and vivid.</p></p><p><p></p></p><p><p></p></p><p><p>Icon Design Example</p></p><p><p></p></p><p><p>In color design, because the traditional Taiji figure in static only two colors, but in the rotation, black and white appears to produce a variety of colors. This color visual perception is applied in the Application.

The project team then plans to complete the digital process of Chen Taiji's other routines, and then digitize and publish other traditional Chinese martial arts projects, such as Chen Taiji and gossip boxing, to the mobile platform. Platforms also extend from a single iOS platform to others, such as Android-based Mobile devices, smart tvs, and More.</p></p><p><p></p></p><p><p>Throughout the mobile platform products, Although the number of large, but the three-dimensional class of less than 1%, this is because the three-dimensional product development needs more time and human resources, the need for a longer period of development. The success of My Tai Chi is in the original development and construction of the model, which allows the data in the laboratory to be spread more widely on this model platform, and the fruits of modern technology can be enjoyed by more people.</p></p><p><p>Debut Siggraph Taijiquan three-dimensional teaching app making secret</p></p></span>
