LottieAnimation-660K
收藏资源简介:
LottieAnimation-660K是由清华大学团队联合多家机构构建的全球最大规模矢量动画数据集,包含66万条经过严格清洗的Lottie格式动画数据。该数据集源自互联网公开的After Effects工程文件,通过Bodymovin插件转换为标准化JSON格式,并经过冗余字段删除等优化处理,文件体积平均减少34%。数据内容涵盖UI动效、卡通插画、多图层场景动画等丰富类型,配套15M静态矢量图形辅助训练。该数据集的建立突破了传统像素视频生成模型的局限,为分辨率无关、可编辑的矢量动画生成研究提供了关键基础设施,主要应用于数字内容创作、交互设计等领域。
LottieAnimation-660K, the world's largest-scale vector animation dataset, was developed by a team from Tsinghua University in collaboration with multiple institutions, containing 660,000 rigorously cleaned Lottie-format animation entries. Derived from publicly available After Effects project files on the internet, this dataset was converted into standardized JSON format via the Bodymovin plugin, and optimized through redundant field removal and other processing steps, leading to an average 34% reduction in file size. The dataset covers a diverse range of content including UI animations, cartoon illustrations, multi-layered scene animations and more, and is paired with 15M static vector graphics to facilitate model training. The establishment of this dataset breaks through the limitations of traditional pixel-based video generation models, providing a key infrastructure for research on resolution-agnostic and editable vector animation generation, and is primarily applied in fields such as digital content creation and interaction design.
