Abstract:The mobile phone 3D animation automatic generation system sends and outputs a 3D animation to the SMS receiver according to the SMS content, through semantic analysis, information extraction, and plot planning. The material of the scene in the animation is the most intuitive way to show the animation, this work starts with qualitative planning and quantitative calculation, and studies the automatic planning of scene material in mobile phone 3D animation automatic generation system. The main task of qualitative planning is to use semantic Web technology to depict all kinds of attributes related to material through ontology database and to associate with relevant themes and templates to get a qualitative description sentence about model material. The main work of quantitative calculation is to depict the qualitative planning results into the specific animation scenes, and to change the material quality of the animation scenes. In the 314 open short messages test, 86.9% of the short messages successfully completed the material planning, among which 71.43% of the text messages planned the material of the original scene in the animation scene library. Experiments show that this method can effectively carry out animation material planning.
