mmABC
收藏资源简介:
mmABC是一个大规模多模态CAD数据集,包含超过130万个基于边界表示(B-Rep)的模型,并带有包括点云、文本描述和多视图图像的多模态注释。该数据集由ABC数据集扩展而来,通过去除相似和多体模型并添加多模态描述构建而成。mmABC旨在促进CAD生成研究,特别是基于B-Rep的生成。该数据集适用于无条件生成和条件生成任务,支持用户根据文本、点云和多视图图像等多种模态输入生成复杂的CAD模型。
mmABC is a large-scale multimodal CAD dataset comprising over 1.3 million boundary representation (B-Rep) based models, paired with multimodal annotations including point clouds, text descriptions, and multi-view images. This dataset is derived from the ABC dataset, constructed by removing similar and multi-body models and adding multimodal descriptions. mmABC aims to advance CAD generation research, particularly B-Rep-based generation. It supports both unconditional and conditional generation tasks, enabling users to generate complex CAD models from multimodal inputs such as text, point clouds, and multi-view images.
