Research And Application Of Animation Post Processing Technology Based On Digital Shadow Performance

This paper is based on the research results of the early digital shadow. In order toturn segment of the animation file into a complete digital animation by processing andsplicing, further studying the animation post-processing technology based on digitalshadow performance. I use the related technologies of software-generation to developdigital shadow animation post-processing platform. And improve the related functionsof original digital shadow performance platform. Mainly includes the following threeparts:1) In addition to bring digital shadow model to completion in the early stage ofthe animation generation, make the controllable movieclip in the process of animationgeneration. Research and analysis the traditional shadow play model and controltechnique of motor performance. By use of flash bone modeling technology andbox2D physics engine to perfect the digital shadow model. Rich the control elementsin the digital shadow performance platform, perfect the digital shadow playperformance platform.2) To edit and modify the property value of a specified node in graphical andinteractive interface way for XML file.Then realize the fine-tuning of action in digitalshadow play animation. The digital shadow play animation generation is based on therecord of key frames. In general, a second records24key frames. When play back theanimation script files, through the control of time orientation changes, the time isconverted to the key frames. Then locate the specified node in the XML file by keyframes. The post-processing work such as save values, modification appears in theform of a graphical and interactive interface to realize the fine-tuning of the digitalshadow play animation action.2) Research the nonlinear splicing technology of XML script file. Put manyanimation script files generated by the program recording for post-processing, stitchedtogether, form a complete digital shadow animation. On this basis, put forward a kindof algorithm that aiming at key frames data in the animation script file for nonlinearsplicing. Combining with examples and experimental analysis, verify the algorithmresearch helps improve the fluency and effectiveness of XML animation script filenonlinear splicing.Finally apply the related technology in this paper to the digital shadow playanimation generation. Experiments prove that through post processing and seamlesssplicing technology to animation script file in this paper, can effectivelypost-processing the digital shadow play script file. Then based on the digital shadowplay performance platform, it shows a more stable and smooth digital shadow play animation. Research significance is to fill the gaps in the digital shadow playanimation files splicing, improve the efficiency of the digital shadow play animationand reduce the cost of the animation. It also provides a new idea for the traditionalanimation.
