| 英文摘要: |
| By investigating and analyzing the deep learning based approaches in 3D shape intelligent generation in recent years, this paper summarizes the problems and challenges of this field and predict the tendency of the future work, to provide a technical reference for researchers in related fields. Firstly, the advantages and disadvantages of the commonly used 3D shape representation methods and datasets are analyzed, such as voxels, point clouds, meshes, implicit functions, etc. Secondly, from the perspective of controllability of 3D shape generation objects, holistic generative methods, structure-aware generation methods and interactive generation methods are reviewed. After that, the evaluation metrics commonly used in 3D shape intelligent generation, such as similarity, diversity and structural consistency of the generation results are summarized. Although the field of 3D shape intelligent generation has made significant development, it still faces great challenges in terms of the size of data sets, the effectiveness of generation methods and the comprehensiveness of evaluation metrics. |
