手机短信3D动画中光照规划的自动生成

摘要

手机短信3D动画自动生成系统是根据发送方短信的内容,经过信息抽取、语义分析等一系列步骤,最终生成一段与短信内容匹配的三维动画并发送给接收方.动画中光照不仅能照明整个场景,还能起到烘托主题、表现氛围等作用.本文重点研究面向手机短信3D动画自动生成系统中光照的自动生成,主要从定性规划和定量计算两方面着手.定性规划的主要任务是通过本体库刻画与光照相关的主题、模板,利用规则库将主题、模板、场景、光照属性等以规则的方式关联起来.定量计算的主要工作是结合具体场景,将定性规划的信息转化为具体数据,然后调用Maya API,将定性规划的结果在Maya场景中实现.%In accordance with the sender's message,through a series of steps such as information extraction and semantic analysis,the SMS automatic 3D animation generating system can generate a 3D animation and eventually send it back to the sender.The animation light cannot only light the whole scene,but can also foil themes,atmosphere,etc.This paper mainly focuses on automatic generation of light in SMS automatic 3D animation generating system,including qualitative planning and quantitative calculation.The qualitative planning describes themes and templates which are about light by ontology.The rule base is used to combine the subject,templates,scene,and illumination properties by rules.The quantitative calculation is combined with the specific scene,the qualitative planning information into specific data,and then calls the Maya API,and the results of qualitative planning in the Maya scene.
