摘　　要：人工智能技术应用于三维建模中,可以简化三维建模的操作,快速生成大量三维模型。若将电影故事板绘画与这类技术相结合,能够让创作者参与到电影预演制作中。近年来,基于草绘的三维建模技术逐渐被应用于数字资产快速生成。我们提出一种基于草绘建模和图像引擎的电影预演制作流程,采用基于草绘的三维建模方法制作电影预演动画所需的数字资产,并设计几何体类建模实验、人物及动物建模实验、用户体验实验。通过邀请50位被试者参与半结构化访谈用户研究,分析其制作效果和使用体验以评估流程的有效性。实验结果表明,我们提出的预演制作流程符合用户制作习惯,能够得到令用户基本满意的动画效果。本文基于草绘的三维建模方法,评估其在电影虚拟预演制作中的生成能力,探讨人工智能生成内容(AIGC)在数字电影制作中的应用潜力。Applying artificial intelligence technology in 3D modeling can simplify the operation of 3D modeling and generate many 3D models in a rapid way.If combining storyboard with 3D modeling,artists can participate in Pre⁃Visualization,also known as PreViz,production.In recent years,sketch⁃based 3D modeling has been gradually applied to the rapid genera⁃tion of digital assets.The authors propose a PreViz production process based on sketch⁃based modeling and game engine,and the sketch⁃based 3D modeling method is used to produce the digital assets.The geometric modeling experiment,hu⁃man and animal modeling experiments,and user experience experiments were designed to analyse the outcomes.This re⁃search invited 50 participants to conduct a semi⁃structured interview study for evaluating the process.The results showed that the process met the requirements of users'habits,and PreViz satisfied its co⁃creators.This research evaluates the generation capability of sketch⁃based modeling for PreViz production,and explores the potential of artificial intelligence gen⁃erated content,which is usually named as AIGC,in digital film production.
